- Precision measurement scale built into the integrated hex key shaft eliminates the need for a separate ruler. Easily measure distances during installation with accuracy. The built-in bearing keeps the guide disk in the correct position for smooth and precise cutting. - Designed for tight spaces. Cuts flush from within the pipe, eliminating the need to open floors. With 6 blades (22mm, 25mm, 32mm, 35mm, 44mm,50mm) and a 3" large guide disk, it accommodates a wide range of pipe sizes, offering economy and convenience. - Premium materials. Hardened stainless steel shaft and high-speed steel (HSS) saw blades ensure sharpness and durability. It cuts PVC, ABS, and soft metal materials with ease, suitable for professionals and beginners alike. - Ease of use. Secure the desired blade onto the shaft, insert the cutter into a 3/8" drill chuck and tighten. Hold the drill perpendicular to the pipe, start at a low speed, and work clockwise until the pipe is cut through. Position the engraved side of the blade upwards to ensure the arrow aligns with the clockwise rotation of the drill. - Use scenarios. In-wall piping retrofit behind floors or ceilings to avoid floor demolition; repairs under sinks or in crawl spaces with limited access; renovation projects where space is tight and flush cuts are required.
