When a broken pipe is lodged inside a fitting, the DAYDOOR 4-inch reamer is designed to clear out the remaining pipe and solvent cement so the fitting can be reused. That can make a repair more direct than cutting out and replacing a sound fitting, particularly when working on plumbing or drainage lines.

A pilot tip helps centre the cutter in the fitting, while the shoulder guides it to the intended cutting depth. The carbide insert has four cutting edges, rotating it presents a fresh edge for continued use. Its aluminium alloy body and hardened stainless steel shaft are made for repeated work, whether the task is a home repair or part of a plumber’s regular toolkit.

Could a fitting be saved instead of removed? For a compatible Sch. 40 connection, this tool gives you a focused way to remove the old pipe material from inside the socket.

What it works with

Use the reamer with standard Sch. 40 PVC, CPVC or ABS fittings. It fits a standard 1/2-inch drill chuck, making it usable with a suitable corded or cordless drill. A high-torque, low-RPM setting is recommended: slower cutting helps reduce heat and the risk of melting the plastic. A high-power corded drill is recommended for demanding work, a light-duty cordless drill may not provide enough torque for a clean cut.

This fitting saver is designed for standard Sch. 40 pipe, not Sch. 80 or high-pressure supply systems. Old, modified or irregular-size pipe may not match standard fitting geometry. When working beside an elbow, allow enough room for the drill and reamer assembly to sit in position.

Tips for day-to-day use

Seat the shaft securely in the drill chuck, then guide the pilot into the fitting so the cutter stays centred. Work at low speed with high torque, letting the tool remove the pipe and cement rather than forcing the cut. The pilot and shoulder help keep the reamer aligned and control its depth as you clear the socket. For a fresh cutting edge, rotate the carbide insert as needed.

This approach is useful when a broken section needs to come out but the surrounding fitting can remain in place. Buyers often praise the tool’s cutting performance and usefulness for plumbing repairs, feedback on stability is mixed, so careful alignment and steady control are important during use.

Questions before you buy

Can it be used with a cordless drill? Yes, it fits a standard 1/2-inch drill chuck and can be used with a cordless drill. A high-power corded drill is recommended for demanding cuts, since a light-duty cordless drill may lack the torque needed for smooth cutting.

Will it ream Sch. 80 pipe? No. It is designed for standard Sch. 40 PVC, CPVC and ABS fittings. Sch. 80 pipe has different internal dimensions, so this reamer is not suitable for it.

Can I use it close to an elbow? There must be enough working space for the drill and reamer together between the elbow or fitting and the pipe. The tool needs room to line up with the socket.

Is it worth it?

For repairs involving a compatible Sch. 40 fitting, the DAYDOOR reamer offers a practical alternative to removing the entire fitting: it clears broken pipe and cement from inside the socket, helping you keep the repair focused. Its four-edge carbide insert, pilot-guided alignment and standard drill-chuck fit make it a useful choice for plumbers and DIYers handling PVC, CPVC or ABS plumbing and drainage work.
