Brief introduction of our DTH drill bits:

DTH hammer bits are used together with DTH hammers to drill holes in various rock types. Combined with a down-the-hole hammer, the drill bit is designed with a spline drive, which can rotate the bit underground. Drill bits come in different sizes and styles, so they can drill holes of various sizes. Our various down-the-hole (DTH) drill bits are made of high-quality materials, which can provide you with a good balance between penetration ability and drill bit life. We offer a comprehensive range of standard and custom drill bits, with a wide variety of tool holders and various bit designs to suit every project.

How to Chose the Right Products

When you are choosing the right bit for optimum performance you have to balance penetration against bit life. There are three head designs for drill bit: Flat Face, Convex and Concave. These are designed for specific applications for different rocks with different hardness and condition.
