Milwaukee Pipe Threader vs RIDGID 700: Which to Buy

Both tools thread pipe up to 2 inches and both accept RIDGID 12-R die heads, so your die sets carry over either way. Buy the Milwaukee M18 FUEL 2874 if you already run M18 batteries and thread where there is no power. Buy the corded RIDGID 700 if you thread occasionally and want the simpler tool.

These are the two hand-held power drives a plumber chooses between for black iron, galvanized pipe and rigid metal conduit. One is cordless and sits on a battery platform you may already own; the other is corded and has ridden on service trucks for decades. They are closer than the marketing suggests in what they cut, and further apart in how they handle.

What Is the Milwaukee M18 FUEL Pipe Threader?

The Milwaukee M18 FUEL Pipe Threader — catalog 2874-22HD as a kit, with Milwaukee’s page for the 2874-20 bare tool now saying it has been replaced by that kit — is a cordless hand-held power drive on the M18 battery platform with a POWERSTATE brushless motor. Milwaukee’s own product page describes it as threading up to 2-inch black iron pipe, stainless steel and rigid metal conduit, and lists a multi-speed selector that Milwaukee says optimizes thread quality across pipe sizes.

Two items on Milwaukee’s feature list matter more than the motor. The first is AUTOSTOP kickback control, which Milwaukee states prevents severe kickback. The second is a dedicated support arm that, per the same page, lets you thread without a pipe stand. Milwaukee also lists ONE-KEY for tool tracking, security and inventory, and an offset die head for threading closer to bends and against walls.

What Is the RIDGID 700 Power Drive?

The RIDGID 700 Power Drive is a corded hand-held power drive. RIDGID’s published specifications describe a single-phase universal motor, a cast aluminum body, a spur gear reduction face gear drive with spring-loaded adapter pawls, and a double-throw reversible switch. RIDGID’s ordering information for model 700, catalog number 41935, gives 26 to 30 RPM at 115 volts, 50 to 60 Hz, single phase, 13 amps.

RIDGID calls it a heavy-duty hand-held power drive designed for its Model 12-R die heads, and states that other RIDGID die heads — 00-R, 00-RB and 11-R — can be used with adapters, and that the drive also runs 258 and 258XL pipe cutters. RIDGID lists a 775 support arm instruction sheet alongside the 700’s own operator manual.

One note on sourcing: RIDGID’s website refused every request from this machine at the time of writing (September 2026), so the figures above were read from an archived copy of RIDGID’s own 700 Power Drive page dated May 2026. Confirm the current spec before ordering die heads.

Milwaukee vs RIDGID: Does the Cord Decide It?

Mostly, yes — because nearly everything else lines up. Both are hand-held power drives, both are published at 1/8-inch to 2-inch pipe capacity, and both run RIDGID 12-R die heads, which is the part buyers assume is the catch and is not. What is left is where you work and what you already own.

Die Head Compatibility

This is the question that decides whether switching brands costs you a die set, and it does not. Milwaukee’s product page states the M18 FUEL threader is compatible with RIDGID 12-R and Reed R12+ die heads. RIDGID’s specifications for the 700 list 12-R die heads, with 00-R, 00-RB and 11-R usable through adapters. A shop stocked with 12-R heads can buy either tool.

If you own no heads at all, that is a separate purchase whichever drive you pick. A RIDGID 36475 12-R ratchet threader set covers 1/2-inch to 2-inch NPT dies and adds a manual ratchet handle: the heads feed whichever power drive you buy later, and the ratchet covers the one fitting you have to thread when the tool is on somebody else’s truck.

Pipe Size Range

Milwaukee publishes 1/8 inch to 2 inches in diameter for the M18 FUEL threader, across coated PVC, black iron, stainless steel, galvanized steel and rigid metal conduit. RIDGID publishes 1/8 inch to 2 inches of pipe capacity for the 700, and adds a bolt-threading range of 1/4 inch to 1 inch when 00-RB die heads are fitted. On pipe, these are the same tool on paper.

Two inches is the working ceiling for both. Past 2 inch you are into stationary machine territory.

Corded vs Battery

The Milwaukee runs on M18 batteries, and Milwaukee publishes over 25 threads on 2-inch pipe per charge. That is a good number for a service day and a poor one for a repipe, where you end up managing batteries instead of pipe. The RIDGID needs 115 volts and draws 13 amps, so it wants a real circuit and a heavy cord — but it never stops to charge.

The honest split: cordless wins on ceilings, roofs, crawl spaces, outdoor gas meter sets, and anywhere a cord is a trip hazard. Corded wins in a shop, and on any day you are threading more than a handful of joints.

Weight and How It Handles

Milwaukee publishes 22.3 pounds for the M18 FUEL threader at 26.3 inches long. RIDGID publishes 25 pounds for the 700 power drive alone at 28-1/4 inches. Fit a die head and a battery to the Milwaukee and the gap narrows, so treat these as two heavy tools rather than a light one and a heavy one.

Both are two-hand tools, and on both the support arm does the real work. Milwaukee lists its support arm as removing the need for a pipe stand; RIDGID publishes the 775 arm for the 700. Buy the arm with the tool. Threading 2-inch pipe off nothing but a wrench and your own back is how people get hurt.

Kickback and Safety

This is where the two published feature lists genuinely differ. Milwaukee names AUTOSTOP kickback control and states it prevents severe kickback, plus a side grip and a die head retention lock so there is no engagement with a spinning die head. RIDGID’s published specifications for the 700 list a double-throw reversible switch and a spring-loaded pawl gear head, and name no electronic kickback control.

That is a difference in what each maker publishes, not a test result, and it does not make the RIDGID unsafe — plumbers have run them for decades. It does mean the reaction when a die grabs is yours to handle. Set the support arm and stand clear of the swing.

Where a Threading Machine Beats Both

Neither of these is a threading machine. If you thread every week, work anything over 2 inch, or want pipe cut, reamed and threaded in one setup, a stationary machine is the tool and no hand-held drive replaces it. That is a different purchase, covered in our guide to pipe threading machines.

How We Pick Threading Tools

Picks here come from field experience on real jobs plus published manufacturer specifications — capacity, weight, motor, warranty — read from the maker’s own documentation rather than guessed, and from the code realities around gas and conduit work. We weigh value over price, and name a small number of genuine winners instead of every item on the shelf. Nobody pays to be included. The full method is on our how we pick page.

Why Trust Plumbing Picks

This site is written and reviewed by a licensed Georgia plumber — journeyman license #JP507711, verifiable through the Secretary of State. There are no paid placements and no manufacturer sponsorships, and the Amazon commission disclosed at the top is identical whichever tool we point you at. More on the about page.

Which Should You Buy?

Buy the Milwaukee 2874-22HD M18 FUEL pipe threader kit if you are already on M18, thread away from power, and want the published kickback control. It is the tool for service work, gas meter sets, conduit runs and anything you have to carry up a ladder.

Buy the RIDGID 45178 700 Power Drive kit, which comes with 1/2-inch to 2-inch die heads, a support arm and a carry case, if you thread occasionally, work where power is a given, and would rather own one tool with no battery platform attached. Milwaukee publishes a 5-year limited warranty on the 2874; RIDGID’s archived 700 page from May 2026 shows a full lifetime warranty, and ridgid.com would not answer in September 2026 to confirm it is unchanged.

If you thread two or three fittings a year, buy neither. A ratchet set and an afternoon does that job, and the money is better spent on a proper pipe wrench you will reach for every week.

FAQ

Does the Milwaukee M18 pipe threader use RIDGID die heads? Yes. Milwaukee’s product page states the M18 FUEL Pipe Threader is compatible with RIDGID 12-R and Reed R12+ die heads. A shop already stocked with 12-R heads does not need to rebuy dies to move to the cordless tool.

What size pipe will the Milwaukee and RIDGID threaders handle? Both are published at 1/8 inch to 2 inches. Milwaukee lists coated PVC, black iron, stainless steel, galvanized steel and rigid metal conduit. RIDGID adds 1/4-inch to 1-inch bolt threading with 00-RB die heads fitted. Past 2 inch you want a stationary machine.

How many threads does the Milwaukee threader cut per charge? Milwaukee publishes over 25 threads on 2-inch pipe per charge. That covers a service day comfortably. On a repipe or a large fit-out you will be cycling batteries, which is the point where the corded RIDGID 700 stops looking like the inconvenient choice.

Is the RIDGID 700 still worth buying? Yes, for the right work. It is corded, 25 pounds for the power drive alone, and 26 to 30 RPM for catalog 41935, and RIDGID’s May 2026 page lists a full lifetime warranty. If you thread near power and do not want another battery platform to feed, it is the simpler tool.

Do I need a support arm? Yes. Both makers publish one — Milwaukee a dedicated support arm on the tool, RIDGID the 775 for the 700. The arm takes the reaction torque that would otherwise go through your wrists. Threading 2-inch pipe without one is how people get hurt.

Bottom Line

The die heads are the same, the published capacity is the same, and the weights are within three pounds of each other. What is left is power. Already on M18 and working away from an outlet, the Milwaukee 2874 is the buy. Threading near power, occasionally, with no interest in another battery platform, the RIDGID 700 is the buy. Either way, buy the support arm with it.
