This workshop is used for the processing of spare parts. The grinding machine with precision ranging from 0.01um to 0.05um allows the high-pressure air hammer to produce fast drilling speed and extremely stable performance. We always achieve great precision to as little as 0.12um. Our monthly output capacity reaches up to 20,000 mechanical and electrical products. In addition, our drill bits are made of ultra-coarse grained cemented carbides and undergo pressure-sintering processes, thus enabling a 30% increase in both hardness and toughness of the drill bit. This makes the drill bit drill longer and deeper saving you precious time and money!
