Wxsoon Extra Long Tungsten Carbide Drill Bit with Inner Cooling

Tungsten carbide deep hole drill processing customized non-standard cemented carbide extended drill manufacturer

Deep hole drill is mainly used to process relatively deep holes. Usually, the drill itself will also have 2 small holes for coolant to pass through, which can be used with the machining center with coolant. The purpose is to reduce the temperature generated during deep hole machining, facilitate the smooth discharge of cutting, and reduce the fracture probability of alloy internal cooling bit.
