TOMINE Tapered drilling bit is made of high-quality alloy steel and tungsten carbide from internationally renowned brands. The drill bit adopts “hot plug” processing steps, and the optimized design of inserting buttons in the same way as internationally renowned brands to increase the drilling speed. Through special heat treatment, the tapered rock bit is made of high-quality raw materials and can be widely used in handheld (short hole) drilling systems. We also provide a variety of cutting structure design configurations, including chisel, cross drill and button drill, for users to choose from. These designs can be used in various rock formations to achieve the highest productivity, high penetration rate and long service life
