KAT DRILLING
1 / 5
High air pressure DTH hammer is a specialized down-the-hole tool designed for high-efficiency percussive drilling in rock formations. Characterized by its robust build and high-pressure capabilities, it is ideal for mining, quarrying, and construction projects. The mechanism utilizes compressed air to drive a reciprocating piston, delivering intense impact energy to the drill bit for faster penetration.
