8 Inch DTH Hammers and Bits

Bits are available in four face shapes—Concave, Convex, Flat, and Double Gauge—paired with three button shapes: Domed, Ballistic, and Semi-Ballistic. This range allows customers to select the optimal combination for their specific formation and drilling conditions.

Three carbide grades are available: Standard, Diamond, and Bluemaxx. Each grade offers different wear resistance and impact toughness properties, allowing operators to select the right balance of durability and cost for their formation type and drilling application.

These bits are engineered for hard, abrasive rock formations and are commonly used in mining, construction, geothermal, oil & gas, and water well drilling where high-impact percussion energy is required to achieve efficient penetration through tough rock.
