Free Returns 47/64″ Reduced Shank Drill Bit HSS 1/2″ 3-Flat Shank D/A3F47/64

This technical description covers the 1 PC 47/64″ Reduced Shank HSS Drill Bit, 1/2″ cutting diameter with a 3-Flat D/A3F shank. Designed to deliver reliable metalworking performance, it combines a standard 1/2″ hole size with a reduced shank to fit larger-bore toolholders while maintaining rigidity and control during drilling. Constructed from high-speed steel, this uncoated bit is intended for general-purpose drilling on common metals with appropriate speeds and feeds.
