3'' Middle Pressure DTH Drill Bit with Flat Concave Convex Drop Center Bit Face

Application                                                                                                                                                         

DTH Drill Button Bits are produced from premium quality nickel-alloy steel for increased durability and wear characteristics. Specific heat treatment standards and special “stress relief” processes ensure consistent performance.

DTH hammer bits are designed for maximum performance and hole cleaning ability and high penetration rate.

We can design and manufacture according to customer's requirement of the down the hole bits Diameter,No. air holes,carbide button shape and the face shape.
