McMaster 4192A62 Long-Life Hole Saw Kit with 9 Saws

The saws in these kits have carbide-tipped teeth—the hardest in our hole saw offering—so they stay sharp up to twice as long as saws with high-speed steel teeth. They also cut through harder sheet metal, wood, and other materials. Each kit contains saws in different diameters for cutting perfectly round holes of various sizes. Often used to remove more material than drill bits, these saws are helpful for jobs such as creating cutouts for doorknobs or cables. Attach them to a drill or drill press with the included arbors.
