Standard Assortment

DTH drill bits to match all conceivable applications. Each 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.

Four basic designs are available: Convex, Flat front, Speed Bit, Concave. These are designed for specific applications for all rock types, hardness’s and conditions Bit life and rate of penetration are the most important criteria in selecting the right bit for a particular application.
