DTH Drilling Bit Workshop DTH Bit: It is mainly a pneumatic rock or ground drilling rig, in which the impact hammer is directly behind the drill bit, so the impact mechanism follows the drill bit down into the borehole. The drill rod transmits the necessary feed force and rotation to the DTH hammer and drill bit, and transmits compressed air to the DTH hammer.

Integral Reaming Bit T38-102mm Thread Type: T38 Reaming Diameter: 102mm Length: 165mm Buttons: 13mm*17 Carbide Design: Dome Weight: 4.57KG Bestlink reaming bit functions to enlarge a borehole and it is designed with a drill portion and a reamer portion. The drill portion is formed by cutting edges at the end of a plurality of flutes, and the reamer portion includes a first relief formed on each flute surface disposed at a predetermined angle with respect to the flute surface to form a first reamer cutting edge. A second relief is formed contiguous with the first face on each reamer portion and is disposed at a second angle, less than the first angle with respect to the flute surface.
