Each High Air Pressure DTH Drill Bit is made from quality alloy steel, and has been precision machined to produce a perfect body, heat treated to the required hardness, given surface compression for fatigue resistance, and fitted with precision buttons manufactured in-house. These are deigned for specific applications for all rock types, hardness's and condition. Bit life and rate of penetration are the most important criteria in selecting the right bit for a particular application.
Our High Air Pressure DTH Drill Bits contain below designs:
--Low air pressure DTH drill bits
