Product Description

 8inch Down The Hole Drilling DTH Hammer for Rock Mining and Well Drilling

DTH hammer is a percussion system driving a piston inside hammer body with up and donw 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.

Bestlink company makes and supplies the finest and most efficient Down-the-Hole (DTH) hammers and bits for the mining, construction and water well industries. Bestlink 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.

Drill and blast engineers and water well contractors trust Bestlink's DTH equipment because of the precision engineering and high standards of drilling efficiency built into each of our hammers and bits.
