KAT DRILLING
1 / 5
High air pressure DTH hammer is an advanced down-the-hole drilling tool designed for percussive drilling in rock formations. Characterized by high air pressure and superior efficiency, it is the ideal choice for projects with abundant air supply. By utilizing compressed air to drive the piston in a reciprocating motion, it generates high impact energy directly to the drill bit.
