Hole Cutter Basics

Carbide tipped hole cutters feature special ultra-hard tungsten carbide teeth, a pilot drill bit and ejector spring. These industrial hole cutters cut longer and faster than hole saws and twist drills, increasing productivity on the job. They are the perfect portable tool for the professional electrician, plumber, mechanic and contractor. For cutting steel plate, iron, aluminum, copper, cast iron, stainless steel, fiberglass and plastics.

Special tungsten carbide teeth provide excellent wear and heat resistance while cutting stainless steel and tough alloys. The one-piece construction requires no assembly, while providing stable accurate drilling. A strong heat resistant ejector spring ejects the slug, saving time, while the safety collar stop prevents over penetration for safer, faster operation.
