DTH Down The Hole Drilling Rig Bottom Bits are made from grade hard alloy and special steel, generally matched with the light-duty rock drill, to drill the rock hole within diameter of 50mm. DTH Drill Bit life and rate of penetration are the most important criteria in selecting the right bit for a particular application. In most cases, the focus is on productivity, so the fast cuttings removal features (Convex/Ballistic designs) are preferable, to ensure the buttons are cutting clean, with the minimum of recrushing.
