Pneumatic Rock Drill Bits and Accessories

Infinity Tool MFG's DTH hammer bits are available from 2 inches to 18 inches (50.8 mm to 457.2 mm), covering 12 distinct shank and connection models including QL40, DHD340, COP32, and Domintor 100. This range supports applications from small-diameter water well drilling to large-diameter mining and construction bores.

Yes. Infinity Tool MFG offers custom manufacturing for non-standard diameters, face shapes, button configurations, and carbide grades. Customers can choose from concave, convex, flat, or double gauge faces, plus domed, ballistic, or semi-ballistic button shapes, or request a fully custom design engineered for specific formation and hammer requirements.

DTH hammer bits are designed for straight vertical or angled percussion drilling in hard rock, while directional hammer bits are engineered specifically for Horizontal Directional Drilling (HDD) applications, allowing steerable pilot holes through mixed or hard formations. Both use tungsten carbide buttons and DTH percussion technology but differ in geometry for their intended drilling path.

Infinity Tool MFG offers three tungsten carbide grades for button inserts: Standard, Diamond, and Bluemaxx. Each grade balances wear resistance and impact toughness differently, allowing operators to select the best option based on formation abrasiveness, hardness, and expected bit life for their specific drilling project.

Yes, these bits are specifically engineered for hard and abrasive rock formations. High-quality steel bodies combined with tungsten carbide button inserts and precision DTH percussion technology provide the impact force and durability needed for efficient penetration in mining, construction, and deep well drilling applications.

These tools serve mining, oil and gas, geothermal, water well drilling, horizontal directional drilling (HDD), and geotechnical/construction industries. Applications range from exploration and site investigation drilling to deep well drilling and underground utility installation, wherever efficient hard rock penetration is required.
