Hard alloys and tool steels push drill bits to their limits. Heat-treated metals, high Rockwell hardness, and alloy compositions resist standard cutting tools, leading to burned-out bits and wasted time. That’s why you need drill bits specifically engineered for alloy and tool steel drilling.

At Drill Bit Warehouse, we supply professional-grade cobalt and carbide drill bits that cut through the toughest steels with precision. Our M42 cobalt bits provide heat resistance and durability for production environments, while our C2 carbide drill bits tackle extreme hardness where nothing else will bite. Split-point and parabolic flute designs improve penetration, reduce work hardening, and extend tool life.
