Tungsten carbide coolant feed drill has 1 or 2 through-hole or double spiral hole and uses compressed air and cutting fluid to cool tool and take chips away. It is particularly suitable for the deep-hole drilling with great cutting heat.Tungsten carbide coolant feed drill mainly consists of drill tip, chip groove, spiral groove, run-out groove, handle and cooling hole. Drill tip: In drilling process, it endures the most part of thrust and torque, which directly affects the quality and the…

Tungsten carbide disc cutter is fabricated by pressing and sintering process, which has good toughness, abrasion resistance, anti-oxidation and crater wear resistance. So it can be widely used in paper cutting, printing, packaging and some electronic fields. Take metal sheet longitudinal cutting as example, it generally uses a pair of upper and lower disk cutter for rolling-shearing process. In the cutting process, the upper and lower disk cutter to maintain the level in the axial gap and radial transfer volume,…
