The Custom Coolant-Through Carbide Drill Bit is a high-performance cutting tool designed for precision hole machining in a wide range of ferrous materials. Made from premium fine-grain tungsten carbide with a 0.4μm grain size, this drill bit offers excellent hardness, wear resistance, and dimensional stability.
Featuring an SP coating with a hardness of HV3800 and a coating thickness of 1–3μm, the tool enhances surface protection and reduces friction during machining. Its internal coolant-through design allows coolant to be delivered directly to the cutting zone, helping to improve heat dissipation, chip evacuation, and machining efficiency.
As part of the Non-Standard Customization series under Custom Drill Bits, this product can be customized according to specific machining requirements, including tool dimensions, geometry, and application conditions.
