CT hole saws are tungsten carbide tipped hole cutters. They are designed for cutting tough materials like steel, stainless steel, fiberglass, and other difficult materials. They cut faster and outlast bi-metal hole saws by up to 50 times, depending upon the application. They cut rounder, more accurate holes.
