DEWALT Impact Connect is an attachment compatible with drills and drivers, designed to quickly and efficiently cut plastic pipes. The cut is made from the inside using a small diamond-coated blade, which handles even reinforced pipe walls. The attachment fits a 1/4-inch shank. The body is made from anodized metal that is damage-resistant, long-lasting, and rust-proof. Depth markings are printed on the surface. It fits pipe diameters from 1-1/4 to 8 inches.
