DTH drilling tool is a kind of drilling system which uses compressed air as motivation, makes drilling impact motivation parts down the hole,

to control the piston reciprocating motion by the distribution device in the hammer, 

and then impacts the DTH bit in the front of the hammer to transit the impacting power to the bit. The DTH bit in the front of the hammer breaks the rock to drill hole.

STAROCKDRILL drilling tools are fitted with proprietary cemented carbide buttons, which are designed to drill further and last longer. 

With a unique combination of strength, hardness and resilience, STAROCKDRILL bits can tackle even the most demanding applications.

All our DTH drill bits are also CAD designed, CNC manufactured for perfect bits body, and multiple heat-treated to enhance hardness, 

surface-compressed for fatigue resistance, all thus to extend the product life for maximum wear and performance in the toughest of drilling conditions.
