CIR90 DTH Drill Bit Diameter 90mm Low Air Pressure Bits For Hammer Drill
DTH Drill Bit
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. Sansung 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.
We can design and manufacture the personalized products to meet your specical apllication, such as changing the tungsten carbide insert profile (spherical, ballistic, etc.), face profile (flat face, concave, convex, etc.), and flushing holes.
