RIDGID
The 238-P operates using a one-half-inch-square impact driver or ratchet. The tool can cut 8-inch diameter thick soil pipes when used with an impact driver or 4-inch thick pipes when used manually. The tool is 11-1/2 inches long, weighs 13-1/2 pounds, and includes a removable handle and low-profile cutter wheels to fit into tight places. The tool's facing chain hook lays on top of the pipe for easier latching, and two-directional cutting allows for a cleaner cut. The tool is protected from overloading by a torque limiter.
