HCB-200 Hole Master® is a drill guide with 6 bushings to work with 1”, 1 3/16”, 1 1/4”, 1 1/2”, 1 3/4”, and 2” hole saws. Light-weight and easily portable, HCB-200 is strong enough for supporting cuts on carbon steel or stainless steel pipe yet lightweight enough to clamp onto PVC and other plastic pipe. It has a 2" - 6" nominal pipe diameter mounting range. Use the Hole Master on depressurized piping systems only. An electric or cordless standard ½” drill is needed. The versatile HCB-200 accommodates any hole saws that fit the operator’s drill and the chosen bushing. There is a thumb screw on the guide that holds the bushing in place.
