Products Description
DTH drilling is a percussion system driving a piston inside hammer
body with up and down motion by compressed air and transmitting an
intensive percussion energy to the bit to enable the drilling by
crushing the rock. Drilling method by DTH hammer exerts high
drilling performance especially for drilling hard rock and
contributes for shortening work schedule. Hence, this method is
widely utilized for foundation work, landslide prevention work,
quarrying services, marine civil work, etc.
KSQ makes and supplies the finest and most efficient Down-the-Hole
(DTH) hammers and bits for the mining, construction and water well
industries. DTH hammers transmit intensive impact energy with low
energy loss. This results in good rock breakage, high penetration
rates and high productivity. The equipment is designed to give
optimal hole quality, reliability, and long service life, as well
as the best blasting results and low total operation cost.
