TOP HAMMER drilling tools include: bit, rod, shank and sleeve. The piston of drill rig directly impacts the shank, makes impact power reach the bit through rod by the form of stress wave, so as to work on the breakage of rock. The primary breaking way is impacting while the secondary is cutting; both are with high drilling efficiency.

DOWN THE HOLE drilling is a kind of big diameter borehole drilling by extending the impacting power to the bottom of the hole. With high straightness, clean hole wall, good rigidity of drill pipe and hammer, without high axial thrust, no restriction of drilling depth and low cost, DTH drilling tools are widely used in open-pit mining.

Adopt high quality steel and tungsten carbide to ensure product quality.
Patented drill bit designs ensure fast footage speed and good quality of drilled holes.
Various specifications are available for production as per customers’ special requirement.
Professional and cost‐effective.

Based on the design of rock drilling tools, the optimized designs of bit improve drilling efficiency.
Apply good quality material, with good ensile stress and elongation, the rod has more reasonable centre hole for well grouting.
Complete specifications and types are offered to meet the requirement of all kinds of engineering projects.
