HRC 70° carbide drill bits
Wholesale Custom HRC 70° Carbide Drill Bits are designed for ultra-hard machining, offering exceptional wear resistance, rigidity, and edge stability for materials up to HRC 70. The 70° cutting angle ensures controlled entry, reduced cutting pressure, and high drilling accuracy on hardened steels, tool steels, die steels, and powdered metals. Optimized flute geometry promotes smooth chip flow and heat dissipation for stable high-speed or high-load operation. Customizable features include diameter, flute length, point angle, shank type, internal coolant, tolerance, and coatings. Ideal for mold making, precision tooling, die processing, aerospace, and high-strength metal applications.
