A tap and a die on one tool
Thread a plastic pipe with the drill you already own.
Cut a male thread on the end of a plain pipe, or a female thread inside a plain socket, and a threaded valve, faucet or adapter screws straight on — no solvent weld, no waiting for it to set. This is a tap and a die on one small aluminum tool: chuck the shaft in a drill, run it onto the pipe, back it off. One tool per size — 1/2 in for 20 mm pipe, 3/4 in for 25 mm pipe — or both in a set.
Read this first: these are metric pipe sizes.
The tools fit pipe that measures 20 mm (0.79 in) or 25 mm (0.98 in) across the outside — metric PP-R, PVC and similar plastic pipe. Most pipe in American homes is a different size: 1/2 and 3/4 in Schedule 40 PVC measure 0.84 and 1.05 in across, and CPVC and PEX measure 0.625 and 0.875 in. None of those is a match. Measure your pipe before you order.

What it actually does
Two threads, one tool
Outside thread. The slotted cup is a die. Line it up with a square-cut pipe end, run the drill, and it cuts a male thread on the outside of the pipe — the slots let the chips out as it goes. Inside thread. Slide the shaft in from the other end and the threaded nose becomes a tap. Run it into the bore of a pipe or a plain slip socket — an elbow, a tee, a coupling — and it cuts a female thread for a male fitting to screw into.
That is the whole job list: male threads on pipe ends, female threads in bores and sockets, in two sizes. It does not cut pipe to length or join it — a pipe cutter and the right fittings still do that.
The part nobody tells you
A good thread starts before the drill does
Nearly every bad plastic thread goes wrong at the start, not in the tool. Cut the pipe square — with a pipe cutter, not a hacksaw — and take the burr off the edge. A slanted end starts the die crooked, and the thread wanders all the way down. Clamp the work. Hold the pipe or fitting in a vise or clamp; a fitting held in one hand spins with the tool.
Run the drill slowly and keep it in line with the pipe. Plastic cuts easily, and speed melts it instead of cutting it: low gear, gentle trigger, and let the thread pull the tool on rather than pushing it. When the thread is as long as the fitting needs, stop, switch to reverse and back the tool off the way it went on. Clear the chips out of the slots before the next cut.
Then wrap the male thread with PTFE tape before the fitting goes on, and tighten it finger-tight plus one to two turns. Plastic threads strip if you keep leaning on the wrench.
Three options
Measure the pipe, then pick the size
The size is set by the outside diameter of your pipe, not by what the fitting is called. Measure straight across it with calipers — or wrap a strip of paper around it, mark where it overlaps, and divide that length by 3.14.
1/2 in — for pipe that measures about 0.79 in (20 mm) across.
3/4 in — for pipe that measures about 0.98 in (25 mm) across.
Both sizes — one of each, each with its own shaft, for less than the two bought separately. The one to get if your run steps down from 25 mm to 20 mm.
Straight answers
Three things we would rather you knew now
These are metric sizes, and US Schedule 40 PVC is bigger. The tools are built around 20 mm (0.79 in) and 25 mm (0.98 in) pipe — the PPR and PVC sizes used across most of the world. Standard US Schedule 40 PVC measures 0.84 in across at 1/2 in and 1.05 in at 3/4 in, and the maker gives no fit for it. If your pipe does not measure close to 0.79 or 0.98 in, this is not the tool for it.
Plastic pipe only. The cutter is aluminum alloy. It threads PPR, PVC and MPP; on steel, copper or brass the teeth will blunt, not cut.
A cut thread is the weakest point of a pipe. Threading takes material out of the wall, which is why pipe makers only thread thick-wall plastic pipe and rate a threaded joint well below the plain pipe. Use it for drains, irrigation, garden lines and projects; for a pressurized supply line inside a wall, use molded threaded fittings. Whatever you thread, pressure-test it before anything gets closed up.

Questions people ask
Before you order
Will it fit US Schedule 40 PVC?
Do not count on it. 1/2 in Schedule 40 measures 0.84 in (21.3 mm) across and 3/4 in measures 1.05 in (26.7 mm); these tools are built around 0.79 in (20 mm) and 0.98 in (25 mm) pipe. Measure yours before you order. Schedule 40 is also too thin-walled to thread for pressure use — pipe makers only thread the heavier Schedule 80.
Is the thread NPT or BSP?
The maker does not say. At 1/2 in and 3/4 in both standards use 14 threads per inch, so fittings of either kind will usually start, but the thread angle differs — 60° for NPT, 55° for BSP. Do not rely on the threads alone to seal: use PTFE tape and pressure-test the joint.
Can I thread metal pipe with it?
No. The tool is aluminum alloy, softer than steel, copper or brass pipe, so the teeth would blunt before they cut. It is made for plastic: PPR, PVC and MPP.
What drill do I need?
Any corded or cordless drill whose chuck closes on the 1.97 in (50 mm) shaft. What matters more is speed: use the low gear and a light trigger. Plastic melts if you rush it, and a melted thread will not hold.
How do I switch from outside to inside threads?
Move the drive shaft to the other end of the tool. From one end the cup faces the work and cuts a male thread on the pipe; from the other, the tap nose faces out and cuts a female thread in a bore or socket. The maker's step-by-step photo above shows both setups.
Can it thread the inside of a fitting?
Yes — a plain slip socket on an elbow, tee or coupling of the matching size. Clamp the fitting firmly first; it will try to spin with the tool.
How much thread should I cut?
Only as much as the fitting takes. Every extra turn is more wall taken out for no benefit. Screw the fitting on by hand as a test — when it bottoms out with thread to spare, you have cut enough.
Which option should I buy?
Measure first. About 0.79 in (20 mm) across: the 1/2 in. About 0.98 in (25 mm): the 3/4 in. Both sizes in the same system: the set, which costs less than the two bought separately and comes with a shaft for each tool.
