A pipe threading machine is a power tool that cuts clean, tapered threads onto the ends of steel, black iron, galvanized, or conduit pipe. It clamps the pipe in a vise, spins a matching die head around it, and takes a job that would otherwise be a long session of hand cranking down to a few minutes per fitting.
That matters more than most buyers expect. Whether a gas, water, or hydraulic joint seals is decided by two things: the quality of the die, and whether cutting oil was applied. We compared the 10 machines below across motor output, die material, pipe capacity, weight, and the volume of owner feedback behind them, so you can pick the class of machine that matches the pipe you actually work with.
There are three classes, and the trade forums keep landing on the same split. A ratcheting hand threader is quiet and unbeatable for a few fittings a week. A hand-held power drive couples to a die head you already own and turns it with a motor. A full machine carries its own stand, carriage, cutter, and reamer, and handles the largest pipe. If you need a cutter that matches the threader, our guide to the best pipe cutters breaks down the options.

Top 3 Picks for Pipe Threading in 2026
RIDGID 700 Power Drive
- 120V hand-held power drive
- 1/8 to 2 inch capacity
- Uses RIDGID 12-R and 11-R die heads
The RIDGID 700 takes our top slot because it pairs the highest owner rating in this group with a solid volume of owner feedback. The Milwaukee M18 FUEL is the one to buy when there is no outlet on the job site. The VEVOR 2300W ships six die sizes covering 1/2 inch to 2 inch in one kit and has the most reviews of any machine here, though its durability split is wide.

1. RIDGID 700 Hand-Held Power Drive – Motor for Die Heads You Already Own
RIDGID 41935 Model 700 Hand-Held 120-Volt Power Drive Pipe Threader, Compatible with RIDGID 12-R, 00-R, 00-RB, and 11-R Die Heads, Silver
120V hand-held power drive
1/8 to 2 inch pipe
24.2 lb cast aluminum
Pros
- Compact enough for tight spaces
- Clean repeatable threads
- Also powers RIDGID 258 and 258XL cutters
- Runs right-hand and reverse-hand threads
- Lifetime warranty
Cons
- Die heads and adapters sold separately
- Needs a 120V outlet on site
- 24.2 lb is heavy for a hand-held tool
The 700 is not a complete machine. It is the motor half of one: a 120-volt drive that couples through an adapter to RIDGID 12-R, 00-R, 00-RB, or 11-R die heads. Owners who already own a ratcheting set usually buy this to stop cranking by hand, and the payoff shows up fast on 1-inch black iron.
It threads pipe from 1/8 inch to 2 inch and handles 1/4 inch to 1 inch bolt threads, so it covers most residential and light commercial gas and water work. The cast aluminum housing and heavy-duty switch are the parts that decide whether it survives years in a van.
Experienced owners describe it as dependable and powerful, and one contractor keeps a Model 700 permanently in the van while relying on a hand threader for smaller work. The same owners flag the two obvious costs: you need a die head, and you need power.
What you get for the money
Nothing but the drive. Plan on buying a 12-R die head for 1/2 inch to 1 inch work and an 11-R or 00-R head when you go past 1 inch, plus the adapter ring. Reviews repeatedly note the die heads are the expensive part of the setup, not the motor.
The one accessory people forget is the reaction arm above 1 inch pipe. Without it the machine tries to counter-rotate instead of turning the die, and the threads come out torn.
Where it falls short
A 24.2-pound tool held at chest height is tiring over a full day, and the 120V cord rules out remote work unless you bring a generator. If your work is all 1/2 inch and 3/4 inch, a ratcheting hand threader will be faster once the machine is unboxed.
2. Milwaukee 2874-22HD M18 FUEL Threader – Cordless Work in a Truck Bed
Milwaukee 2874-22HD M18 Fuel Pipe Threader w/ONE-Key Kit
18V M18 FUEL cordless
22.3 lb with two batteries
ONE-KEY locking
Pros
- No generator or extension cord needed
- Owners report more speed than a RIDGID 700 corded head
- Threads pipe straight from a truck bed
- Two batteries and charger included
- ONE-KEY theft protection
Cons
- One buyer reported low-speed failure above 1-1/2 inch
- One buyer reported slow warranty support
- Most expensive item here if a unit fails
Yes, Milwaukee makes a pipe threader, and it is the newest class in this group. The 2874-22HD runs on the M18 FUEL platform, so if you already own Milwaukee batteries and a charger, the whole job starts at the pack level.
Gas fitters and mechanical trades report real throughput on threaded steel and iron pipe. Reviewers say it beats the corded power head they moved away from, and one describes plenty of torque on 1-inch pipe without bogging, off a single battery charge.
That convenience is the whole pitch in a lot of service work. You clamp the pipe, thread it in a parking lot, and there is no cord to trip over and no outlet to find.
How it performs
The 22.3-pound weight is the threader plus a second battery, and it stays balanced in one hand for 1-inch work. Owners consistently describe the low-speed torque as the reason it does not stall on black iron.
ONE-KEY is the feature most service businesses notice. A locked tool can be left on a bench without walking away from your whole machine.
What to watch
The single most-cited negative review reports a new machine whose low-speed setting failed on pipe over 1-1/2 inch, plus slow response from brand support during the warranty claim. Treat that as one report, but buy from a seller with a straightforward return path.
Because this is a battery platform, confirm your existing M18 packs are the fuel generation before you commit.
3. VEVOR 2300W Electric Pipe Threader – Six Die Sizes in One Kit
VEVOR Electric Pipe Threader, 2300W Pipe Threading Machine with 6 Dies 1/2″-2″, 110V Hand-held Pipe Threader Machine with Copper Motor, Portable Electric Pipe Threading Kit with Carrying Case
2300W at 22 RPM
1/2 to 2 inch range
Six replaceable dies
Pros
- Highest review count in the roundup at 70
- Real torque for a hand-held unit
- Six die sizes cover 1/2 to 2 inch
- Fixed bar
- clamp
- oil can
- spare brushes
- Light at 16.8 lb for a hand-held unit
Cons
- Die breakage reported
- especially on 3/4 inch
- Several verified reviews report early failures
- Carbon steel dies wear faster than high-speed steel
- Replacement die service is slow
This is the highest-volume listing we reviewed, with 70 ratings behind it, and it is also the most polarised. A committed group of experienced tradespeople praises the torque for the size of the machine. Against them sits a steady stream of one-star reports from several countries.
The 2300-watt motor runs at 22 RPM with all-copper core coils and covers 1/2 inch through 2 inch using six replaceable dies. Owners doing 1-inch and 1-1/4-inch rigid conduit report running a dozen-plus pieces without trouble, provided the pipe is clamped tight and oiled generously.
At 16.8 pounds, this is among the lighter hand-held machines in the roundup, which makes it easier to hold for long stretches than the 24-pound and 28-pound units.
Best-case use
One experienced group of buyers treats this as a legitimate trade tool rather than a novelty, with two habits doing most of the work: clamp the pipe hard, and use plenty of cutting oil so chips wash away instead of packing against the die. For 1/2 inch to 1 inch black iron and galvanized work in a service van, the size and reach of the kit are hard to argue with.
Where it disappoints
Several buyers report the 3/4 inch die breaking, and multiple verified reviews describe the machine failing after only a few operations. Threads that are hard to start are reported often enough to plan for: back the die off, clear the chip, and start again.
Carbon steel dies are the root of most complaints. They dull far sooner than high-speed steel, and replacement requests are handled slowly.
4. RIDGID 15682 Model 300 Power Drive Complete – The Full Machine Package
RIDGID 15682 Model 300 Power Drive Complete, 38 RPM Pipe Threading Machine with 1/2-Inch to 3/4-Inch, 1-Inch to 2-Inch Universal Alloy Threading Die Heads, Oiler
38 RPM 115V AC machine
212 lb with stand
1/2 to 2 inch alloy dies
Pros
- Arrives complete with dies
- cutter
- reamer
- carriage
- stand
- Folding legs
- locking tray and transport wheels
- Carriage also handles roll grooving
- Full lifetime warranty on workmanship
Cons
- 212 lb means two-person handling
- One in five ratings is a single star
- 115V AC only
- so no off-grid work
The Model 300 Complete is bought for the bundle, not the motor. You get the 38 RPM power drive, a stand with folding legs, a 311 carriage, a reamer, a cutter, 1/2-to-3/4-inch and 1-to-2-inch universal alloy die sets, an 811A self-opening NPT die head, and an oiler in one package.
The reversible 1/2 HP universal motor and RIDGID speed chuck give it the feel of shop equipment rather than a hand tool. The carriage supports roll grooving as well as threading, so contractors with grooving work can justify it on that alone.
Owners value the folding legs, the locking tray, and the transport wheels, which is what makes a machine this heavy movable at all. Universal alloy dies across the 1/2-to-2-inch range mean one die set covers most of the work, and alloy steel holds an edge far longer than the carbon steel supplied with budget kits.
Moving it to a job site
Rolling it to a job site is realistic with the legs folded, which is where the two-person handling rule comes from. The carriage and 38 RPM drive do the work of a shop unit without needing a fixed bench.
Where it disappoints
One in five ratings is a single star, and for a machine at this level that signals the setup experience does not always match the cost. Budget time for alignment and oiling before the first cut.
The 115V AC requirement also rules it out for remote or off-grid sites, and the carriage is a bonus only if you actually run grooving work.
5. Steel Dragon Tools 550 – Compact Work From 1/2 Inch to 1-1/4 Inch
Steel Dragon Tools 550 1/2″ – 1 1/4″ Portable Handheld Pipe Threader Threading Machine
1800W 110V at 25 RPM
1/2 to 1-1/4 inch
28 lb with case
Pros
- Light and compact for a 1.5 HP class machine
- Four die sizes plus support arm
- spare brushes and case
- Forward and reverse release switch
- Good value for light-trade work
Cons
- Stops at 1-1/4 inch capacity
- 12 percent of reviews are 1 star
- No customer photos to judge finish
- Die condition is hard to verify visually
The 550 suits anyone who wants more than a hand ratchet but rarely touches pipe larger than 1-1/4 inches. The 1800-watt, 110-volt motor runs at 25 RPM and the machine weighs 28 pounds, so it is easy to carry and operate with one hand.
The accessory kit is the value story. You get die heads and dies for 1/2 inch, 3/4 inch, 1 inch, and 1-1/4 inch, plus a support arm, replacement brushes, and a carrying case.
Half of owners rate it five stars and describe a capable unit for that size range. The 12 percent one-star share points to some durability disappointment.
Where it fits
Repair work, small residential rough-ins, fuel-line connectors, and any job where the pipe never gets past 1-1/4 inch. The separate forward and reverse switch makes it easy to stop the cut, back off, clear the chip, and resume.
Owners running commercial kitchen suppression piping tend to reach for a compact unit like this, since the whole point is getting it to the work and threading in place.
Where it stops
There is no path past 1-1/4 inch, and plenty of gas and mechanical work sits at 1-1/2 inch and 2 inch. If that is your day, look at a machine with 1/2-to-2-inch coverage instead.
There are also no customer photos to check, so judge it on the accessory list and the return policy rather than on appearance.
6. HinLIaDa 2300W Electric Pipe Threader – Entry Six-Die Kit
HinLIaDa Electric Pipe Threader, 2300W Pipe Threading Machine Heavy-Duty Hand-Held Power Drive Kit Portable With 6 Dies 1/2-Inch to 2-Inch Pipe Threading Die Heads, Ratchet Pipe Threader Kit
2300W pure copper motor
1/2 to 2 inch, six die sizes
External brush port
Pros
- Entry-level build with 2300W claimed
- Six die sizes from 1/2 to 2 inch
- Brushes change without dismantling the tool
- Compact handle reported to reduce fatigue
- Handles galvanized
- iron and tube
Cons
- Thin listing with few published details
- 14 percent of reviews are 1 star
- No weight or dimensions published
This is the entry point of the group, and at 4.1 average it rates better than most of the machines above it. The 2300-watt pure copper motor covers 1/2 inch to 2 inch with six die sizes, and the fixed rod holds the pipe steady during the cut.
The detail that stands out is the external carbon brush port. On most hand-held threaders, a brush change means pulling the machine apart. Here it does not.
Buyers respond to the power-to-cost ratio and to the six-die package covering the full range in one box.
Who should buy it
A weekend installer or a trade apprentice who wants to cover 1/2 inch through 2 inch without a second machine. The forward, reverse, lock, and start switch layout gives you proper control of the cut.
There is also a heat dissipation window in the housing, which matters more than it sounds if you run long threads back to back.
What to accept
The evidence here is thin at 21 ratings, so read the 4.1 as indicative rather than proven. Fourteen percent are one star, so some quality and durability complaints exist.
No weight or dimensions are published, and no owner photos were available to verify the build. Treat it as a light-duty machine for occasional use rather than a daily shop tool.
7. HOTYELL 2300W NPT Threader – High-Speed Steel Dies
HOTYELL Electric Pipe Threader, NPT Threading Machine, 6 HSS Dies 1/2″-2″
2300W at 26 RPM
Six HSS dies, 1/2 to 2 inch
32.9 lb
Pros
- High-speed steel dies cut cleaner threads
- Aluminum alloy die heads resist fracture
- 1/2 to 2 inch covered by six dies
- Six spare brushes included
Cons
- One buyer reported failure after seven pipes
- Another reported it would not cut 2 inch
- Cutting oil not included
- Only 14 ratings
- so durability is unproven
On paper this is among the best-specified hand-held machines in the roundup. The 110-volt, 2300-watt motor uses pure copper windings with a silicon-lamination stator rated at 26 RPM, and the six dies are high-speed steel rather than carbon steel, covering a 20.9 to 59.6 mm range.
That die material is the reason to care. High-speed steel holds its edge on black iron and galvanized pipe where carbon steel dies dull and start tearing the thread. The aluminum alloy die heads are claimed to be lighter than cast iron and less prone to fracture.
Why the die material matters
A dull die is the most common cause of a thread that will not seat cleanly and a fitting that will not stop leaking. Six spare brushes ship in the box, more than most competitors include.
Owners confirm it does the job and consider it good value, which is the right read at this specification level.
What to watch
Fourteen ratings is the smallest base here, and a quarter of them are one star. One verified buyer stopped at seven pipes, and another says the 2 inch die would not cut despite being inside the stated range.
Cutting oil is not included, and on a machine like this it is not optional. Buy a can before the first thread.
8. VEVOR 750W 3-in-1 Threading Machine – Threads, Reams, and Cuts on a Stand
VEVOR Electric Pipe Threader Machine, 750W 28RPM Threading Cutting Machine, 1/2 to 2 inch Pipes Threading Cutter Tool with Foot Pedal for Plumbing, Automotive Repairs, Metalworking
750W at 28 RPM
1/2 to 2 inch, three functions
140 lb with stand
Pros
- Heavy all-metal build
- Three-in-one threading
- reaming and cutting
- Foot pedal for hands-free control
- Quick-release chuck runs up by hand
- Runs on only 750W
Cons
- Steep learning curve on scale and depth
- Instructions lack detail
- Foot pedal is on and off only
- One reviewer reported dies would not bite 3/4 inch conduit
- Two people needed to assemble the stand
This is a bench-style machine rather than a hand-held one, and it does three jobs: threads, reams, and cuts pipe from 1/2 inch to 2 inch. The 750-watt motor runs at a stable 28 RPM in heavy cast steel on a three-legged stand.
Owners who get it working describe a heavy, stable machine that produces clean threads and handles PVC as well as metal. The foot pedal leaves both hands free for pipe positioning, and the chuck releases by hand for fast repetitive work.
It also runs on a modest 750 watts, so it can be powered from more than a standard outlet.
Best-case setup
The learning curve is real, and it sits in the scale and the thread-depth adjustment. The pipe scale is not colour-coded by die size, so mark the settings yourself once you find them.
For a shop doing steady 1/2 inch to 1 inch work, the foot pedal and quick-release chuck are what make the throughput feel good once you are set up.
Where it disappoints
One-star reviews report dies that will not bite, and one reviewer found the teeth would not grip 3/4-inch rigid conduit. Replacement dies were also reported as slow to arrive.
At 140 pounds the stand needs two people to assemble, and the legs make the machine easier to tip. The foot pedal is a simple on and off with no speed control.
Owner photos show the size honestly: this is a machine that owns a corner of a shop rather than a slot in a van. Plan the floor space before you buy.
9. Steel Dragon Tools 1215 – 1-1/2 Inch Capacity That Accepts RIDGID Dies
Steel Dragon Tools 1215 1-1/2″ Power Pipe Threader Threading Machine with 811A Self Oiling Die Head fits RIDGID 47770 47765 47760 Dies
1.5 HP for pipe to 1-1/2 inch
811A self-oiling die head
Fits RIDGID dies
Pros
- Accepts RIDGID 47770
- 47765 and 47760 dies
- Cuts
- reams and threads in one head
- Compact enough to transport
- Owners report it paid for itself on a first job
Cons
- Bundled dies criticised
- one report of straight bolt-like threads
- One buyer reported threads not meeting US NPT
- Rated 3.7 with a mixed 22-rating base
- 119 lb needs two people or a cart
The reason to look at the 1215 is its die head. It uses an 811A self-oiling universal head that fits RIDGID 47770, 47765, and 47760 dies, so you can drop better dies into a cheaper machine and get noticeably cleaner threads.
At 1.5 HP it handles pipe up to 1-1/2 inch, and the package includes the die head, dies, cutter, and reamer. Commercial piping contractors use it for restaurant fire systems and ventilation work.
Owners report good value against higher-priced equivalents, and one said it paid for itself on a first job.
Buy the dies separately
The most useful review on this listing is the four-star one advising you to buy RIDGID dies rather than use the bundled set. Long-term owners point to the same conclusion, and it also connects you to our pipe cutter comparisons when you rebuild the set.
The self-oiling head feeds oil to the die as it cuts, which cuts down on the chip packing that causes torn threads.
What to verify
One verified buyer reported threads that were not compatible with the US NPT standard, and another described output that looked straight, like a bolt rather than a taper. If code compliance matters, check a cut against a known-good NPT male before the pipe goes into a wall.
The oil pump and claw wear quickly according to long-term owners, and at 119 pounds most people plan to put it on a cart.
Owner photos of this machine show it running on a cart, which is the arrangement most buyers settle into within a few weeks.
10. VEVOR 900W Two-Speed Threading Machine – Pipe Up to 4 Inches
VEVOR Electric Pipe Threader Machine, 900W 2-Speed Threading Cutting Machine, 1/2 to 4 inch Pipes Threading Cutter Tool with Foot Pedal for Plumbing, Automotive Repairs, Metalworking
900W at 11 or 24 RPM
1/2 to 4 inch range
279 lb with four-leg stand
Pros
- Threads 1/2 inch to 4 inch
- more than any other machine here
- Two-speed adjustment suits mixed diameters
- Four-legged stand is more stable
- Foot pedal frees both hands
- Steel construction for heavy work
Cons
- No written customer reviews were captured
- 279 lb is the heaviest here
- Foot pedal offers only the two fixed speeds
- High cost for a 3.5-star machine
This is the largest capacity machine in the group, covering 1/2 inch through 4 inch. The 900-watt motor runs at two speeds, 11 and 24 RPM, and the kit includes dies plus a spare die head, oil can, hex keys, a screwdriver, a storage bag, and the leg screws.
Two speeds is the real advantage over the single-speed version, because large-diameter pipe needs a slower feed rate and small-diameter pipe needs momentum. The four-legged stand is more stable than the three-legged model.
It threads, deburrs, and cuts, so it covers the same three functions as the 750W machine at a much larger scale.
Who needs this size
Contractors running 2-1/2-inch to 4-inch pipe: industrial and structural steel work, mining and facilities maintenance, and large commercial mechanical systems. For ordinary 1-inch gas and water work, this is more machine than the job needs.
Steel construction and the 900-watt motor suit heavy steel-processing and automotive work as well as plumbing.
What to weigh first
No written customer reviews were captured for this listing, so the experience is largely untested. The 3.5 average is shared with the 750W version, where the split ran along durability lines.
At 279 pounds it is the heaviest machine here, and it needs a dedicated work area; the foot pedal gives you only the two fixed speeds with nothing in between.
The owner photos show the footprint rather than the finish. Measure the room before committing to a machine this size.
How to Choose a Pipe Threading Machine
Start with pipe capacity, not brand. Most mistakes come from buying for 1/2 inch work and discovering the 1-1/2 inch gas connector will not fit. Decide the largest diameter you will touch, then buy coverage above it.
Check the die material before the motor wattage. Carbon steel dies dull quickly on black iron and galvanized pipe. High-speed steel dies last far longer and cut a cleaner thread, and replacement dies are the part you will buy again and again.
Choose the power source that matches the job site. A 115V corded machine needs a dependable outlet. A cordless M18 FUEL tool works in a truck bed or a crawlspace. A bench machine needs a 110V circuit and floor space.
Budget the reaction arm. Above 1-inch pipe, a power threader needs a reaction arm to absorb torque. Without one, the tool counter-rotates and the threads come out ragged. It is the most commonly forgotten accessory on the list.
Count the accessories you still need to buy. A complete setup is a pipe vise, a pipe cutter, a reamer, a die head with dies, an oiler, a bucket, and cutting oil. Some kits above include most of that; a bare power drive includes almost none. For holding and positioning the pipe, see our best pipe clamps, and if you work overhead, our pipe locators comparison covers support setups.
Decide rental against buying on volume. If you will thread a few fittings a year, most plumbing supply stores will cut threads for you or rent a machine by the day. The buy case gets strong as soon as the pipe is on the truck more than a couple of days a week.
Thread Standards Explained: NPT, BSP, and Die Heads
NPT stands for National Pipe Taper. It is the standard in the United States for steel, black iron, and galvanized gas, water, and hydraulic lines, and the threads taper so a sealant can wedge into the flank and seal under pressure. Nearly every machine in this roundup is built for NPT, so confirm the die set is NPT before you cut.
BSP stands for British Standard Pipe. BSP threads are parallel, not tapered, and the common forms are distinguished by their thread angle. None of the ten machines here carries a BSP die set, so if you are working outside the US, check with the supplier before buying.
A die head is the carrier that holds a die and bolts to the machine or a ratcheting handle. A drop head is the same thing sized for hand threading. The reaction arm is the brace that takes the torque above 1 inch. These three terms explain most of what separates one machine from another.
On technique, the trade advice repeats itself: clamp the pipe properly, ream the inside before threading, flood the cut with cutting oil, and back the die off every turn or two to clear chips. Pushing hard without oil is what causes galling and stripped threads.
One more point on code: gas line work is the safety-critical case. Cut to the standard your local code requires, verify a test cut against a known-good NPT male, and use the right sealant. A thread that looks clean is not always a thread that conforms.
Frequently Asked Questions
Which pipe threader machine is considered the best?
For most trades, the RIDGID 700 hand-held power drive is the best overall choice, because it carries the highest owner rating in our group and turns RIDGID 12-R, 00-R, and 11-R die heads already in circulation. Choose the Milwaukee M18 FUEL if you need cordless operation, and a full machine such as the RIDGID 300 Complete if you thread pipe above 2 inches regularly.
What type of tool is best for threading pipes?
It depends on volume and pipe size. A ratcheting hand threader suits a few fittings a week. A hand-held power drive covers 1/2 inch to 2 inch pipe at speed. A bench machine with its own carriage handles cutting, reaming, and threading plus pipe up to 4 inches. Most plumbers end up owning the middle option.
Which brand of pipe threader is best?
RIDGID is the most established name, with die heads and parts available almost anywhere plumbing supplies are sold and a lifetime warranty. Milwaukee leads the newest cordless class with the M18 FUEL platform. VEVOR, Steel Dragon Tools, and HOTYELL cover the mid-range, where specification is good but review evidence on long-term durability is thin.
Does Milwaukee make a pipe threader?
Yes. The Milwaukee 2874-22HD is an 18V M18 FUEL cordless pipe threader sold as a kit with two batteries, a charger, and ONE-KEY anti-theft locking. Owners report it handles 1-inch pipe without bogging on a single charge and threads pipe straight from a truck bed.
How long do threading dies last, and what causes bad threads?
High-speed steel dies on black iron outlast carbon steel dies by a wide margin, which is why several budget kits report breakage. Bad threads usually trace to dull dies, a loose pipe clamp, or skipped cutting oil. Back the die off every turn or two to clear chips and ream the bore before you start.
Conclusion: The Best Pipe Threading Machines by Scenario
The best pipe threading machine for a working plumber is the RIDGID 700, because it turns die heads you can buy anywhere and carries the strongest owner feedback of the professional options in 2026. For job sites without power, the Milwaukee M18 FUEL is the pick, and for a complete shop package with a carriage and stand, the RIDGID 300 Complete covers cutting, reaming, and threading in one box.
Below that line, treat the mid-range machines honestly. The VEVOR 2300W and the HinLIaDa kit reach 1/2 inch to 2 inch on a modest budget, and the HOTYELL package is the strongest-specified of them thanks to high-speed steel dies. Buy extra dies and cutting oil before the first cut, and check the reaction arm requirement above 1 inch.
