Mask machine is a machine used for automatic production of multi-layer flat masks such as N95 masks and surgical masks. Tungsten carbide drill that plays the role of drilling on the mask machine is made of fine-grained cemented carbide, which has high strength, good toughness, high temperature resistance, good corrosion resistance, high hardness, good wear resistance, smooth chip removal, and small calorific value for drilling.

Tungsten carbide drill for applications of mask machine is polished by the advanced grinding process with sharper edge to reduce the cutting force, reduce the breaking rate of drill, and improve the quality of wall of hole. All parameters of the drill, such as core thickness and core taper, have been carefully designed.
Because of its durability, tungsten carbide can be rather expensive so that is why industries are using more recycled tungsten carbide drills. Carbide recyclers are collecting scrap carbide from various industries and machine shops to process through carbide recycling methods.
