Fein Annular Cutter: 1 5/16 63134333041

High-speed steel (HSS) annular cutters These cutters are the industry standard for general-purpose metal drilling. Utilizing a hollow geometry, they cut only the material at the periphery of the hole, converting a minimal fraction of the material into chips. This results in smooth-walled, burr-free holes while requiring significantly less power and time than traditional twist drills. They are highly effective for a wide range of materials, including mild steel and aluminum.
