Fein Annular Cutter Set TiN, 1 In Cut D, 5 Pc 63134999012

5-Piece Cobalt TiN-Coated Annular Cutter Set, 3/4" Weldon Shank This premium 5-piece annular cutter set is engineered for high-performance drilling in the most challenging materials, including stainless steel, armor plate, and high-tensile alloys. Manufactured from M42 cobalt high-speed steel and enhanced with a Titanium Nitride (TiN) coating, these cutters provide exceptional heat resistance and surface hardness. The TiN treatment acts as a thermal barrier, reducing friction and allowing for significantly faster cutting speeds and a longer service life. Featuring a 3/4" Weldon shank, this set ensures a secure, slip-resistant connection with standard magnetic drill presses, making it an essential kit for heavy-duty industrial fabrication and precision metalworking.
