Rock Drill Bits for Hammer Drilling

For hard, abrasive rock, DTH hammer bits with tungsten carbide buttons are generally the most effective choice, offering high penetration rates and long service life. The optimal bit depends on formation hardness, hole diameter, and hammer system compatibility; options like Diamond or Bluemaxx carbide grades and specific face shapes (concave, convex, flat) further optimize performance for specific conditions.

Rock drill bits for hammer drilling are available across a wide diameter range, typically from 2" to 18" (50.8 mm to 457.2 mm), covering models such as Domintor 100, MACH 20, COP32, DHD 340, QL40, and more. This range accommodates everything from small geotechnical investigation holes to large-diameter mining and water well bores.

DTH hammer bits are designed for straight, vertical or angled percussion drilling and are used broadly across mining, construction, and water well applications. Directional hammer bits are engineered specifically for Horizontal Directional Drilling (HDD), enabling controlled steering through varied formations while maintaining the high-impact penetration benefits of DTH technology.

Rock drill bits are offered in Standard, Diamond, and Bluemaxx carbide grades to match varying formation hardness and abrasiveness. Face shape options include Concave, Convex, Flat, and Double Gauge, with button shapes available in Domed, Ballistic, and Semi-Ballistic configurations to optimize penetration rate and bit longevity for specific rock conditions.

Yes, custom manufacturing is available for non-standard diameters, face shapes, button configurations, and carbide grades. Customers can consult directly with the manufacturing team to design bits tailored to unique formation types, hammer systems, or project requirements, in addition to selecting from the standard off-the-shelf product range.

Rock drill bits for hammer drilling are widely used across mining, construction and geotechnical engineering, oil and gas exploration, geothermal energy, water well drilling, and Horizontal Directional Drilling (HDD) for underground utility installation, wherever efficient penetration through hard or abrasive rock formations is required.
