Product Description

The DHD340A-127 DTH hammer bit features a flat face design with dome carbide buttons and DHD340A shank. Engineered specifically for mining applications, it delivers excellent penetration rates and steel wash resistance in hard to very hard and abrasive rock formations with high air pressure.

Embedded PDC Cutters for Higher Penetration in Hard Rock

The DHD340A-127 DTH drill bit incorporates strategically embedded premium PDC cutters to reinforce the gauge area and improve drilling efficiency in demanding mining environments. By combining high-strength carbide buttons with wear-resistant PDC cutters, the bit maintains excellent hole quality while reducing gauge wear during continuous drilling.

The flat face design promotes stable rock contact and efficient energy transfer, making this model particularly suitable for quarrying, bench drilling, and production blast hole applications. The embedded PDC cutters help extend the service life of the bit, reduce maintenance frequency, and deliver reliable performance in hard and highly abrasive rock formations where consistent penetration and durability are essential.
