Low Air Pressure DTH Drilling Tools CIR90 SPM90 DTH Hammer Bit Hot Sell CIR Bits
Description
DTH (Down to Hole) drill bit, also called spline connected drill bit, is mainly used in large scale mine (open and underground), open quarry and construction. The hammer is situated down the hole in direct connected with the drill bit with splines in the bit. The hammer piston strikes the drill bit resulting in an efficient transmission of the impact energy and insignificant power losses with the hole depth.
JCDRILL has a comprehensive range of 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. 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.
