KSQ Down The Hole drill bit s are produced from premium quality alloy steel for increased durability and wear characteristics.

Specific heat treatment standards and special "stress relief" processes ensure consistent performance.

KSQ DTH hammer bits are designed for maximum performance and hole cleaning ability and high penetration rate.

At present, DTH drilling tool is widely used in underground mining, quarries, hydraulic and Hydro-Power Engineering, water well drilling, Mineral exploration, anchoring hole drilling, geothermal engineering, Subway excavation, another civil engineering. it has the advantage of high flatness, smooth hole wall, high rigid of drill rod and hammer, independent of high axial thrust, no limit of drilling depth, low cost of devices and easiness to maintain. At the drilling hole of dia.105mm-dia.254mm, a plenty of the DTH drilling tools are used.
