Premium Cobalt Drill Bit Set for Hardened Steel

The HIDOTOL Cobalt Twist Drill Bit Set 115Pcs is a premium quality tool designed for drilling through a variety of tough materials. Crafted from M35 High Speed Steel with 5% Cobalt, this set offers exceptional heat and wear resistance, making it particularly well-suited for cutting through hardened metals like stainless steel, cast iron, high-temperature alloys, and titanium alloys, as well as hard plastics and woods.
