High Penetration 254mm - 381mm Size Carbide Tipped DTH DrillDrill Bits for Tunneling Mining

Down-the-hole rock tools (drilling tools) are rock drilling equipment which takes compressed air as power source to partially transfer impact power into drilling holes. An air distributing device in a top hammer controls a piston to move back and forth. An impact device arranged in the front of the top hammer transfers the impact powder to a down-the-hole bit to crush rocks.

DTH rock drill bits are the tools of cutting rock. KSQ DTH bits are made of superior quality alloy steel which is made by Timken in U.S. Besides, all our DTH bits are using the brand "Element Six" T.C carbide which provides (the T.C buttons) for Boart Longyear. In addition art manufacturing technology makes our DTH bits with higher and more reliable quality.
