The Dremel 1-1/2-Inch EZ Lock Rotary Tool Cut-Off Wheels make it easy to cut through metal. These reinforced cut-off wheels last up to two times longer than typical fiberglass wheels. These wheels can be used for cutting metal conduit and PVC piping, reslotting screw heads, and removing rusty nail heads. The EZ Lock design makes changing accessories as easy as a pull, twist, and release, with no worry of losing a screw or needing a wrench. This pack includes five cut-off wheels.
