Masonry and Concrete Rock Drill Bits

For stone and masonry, tungsten carbide button bits—particularly DTH hammer bits or drag bits with alloy steel blades—offer the best combination of durability and cutting efficiency. The right choice depends on stone hardness, hole diameter, and whether percussion or rotary drilling equipment is being used.

DTH hammer bits use percussion action combined with carbide buttons to fracture hard rock, making them ideal for hard formations. Tricone bits use three rotating cones with inserts to crush and shear rock, performing well across soft to hard formations. DTH bits generally drill faster in hard rock, while tricones offer broader formation versatility.

Yes, Infinity Tool MFG offers custom manufacturing for non-standard diameters, face shapes, button configurations, and carbide grades. Our in-house engineering team works with customers to design bits tailored to unique formation conditions, hole sizes, and drilling equipment specifications.

Our DTH hammer bits are available from 2 inches to 18 inches (50.8 mm to 457.2 mm) in diameter, with 12 distinct shank and connection models including QL40, DHD340, COP32, and Domintor 100 to match virtually any DTH hammer system.

Our drill bits are constructed from high-quality steel bodies fitted with tungsten carbide buttons or alloy steel blades, depending on bit type. Carbide grade options include Standard, Diamond, and Bluemaxx, selected based on formation hardness and abrasiveness to maximize bit life and penetration rate.

In-stock items typically ship within 2 working days from our Benton, Illinois facility. Expedited or urgent shipments can be coordinated upon request. Custom-manufactured bits may require additional lead time, so contact our sales team for specific project timelines.
