The Bi-Metal Hole Saw features a patented tooth set design that delivers faster hole cutting. The saw?s solid cap minimizes runout and vibration for a more accurate cut. With a cutting depth of 1?15/16?, the saws are designed for general purpose use across a wide range of materials including wood, plastic, machinable metals, stainless steel alloys, and nail-embedded wood. An enhanced side slot offers increased leverage for faster and easier slug removal.
