Carbide Mining Drill Bits

DTH (Down-The-Hole) hammer bits use tungsten carbide buttons and percussive impact to fracture hard, abrasive rock, making them ideal for mining and hard rock formations. PDC bits use polycrystalline diamond compact cutters for continuous rotary cutting, offering faster penetration in medium to hard formations with less vibration.

Infinity Tool MFG offers DTH hammer bits ranging from 2" to 18" (50.8mm to 457.2mm) across 12 shank/connection models, along with tricones, PDC bits, and hole openers in various sizes to match virtually any drilling rig or application requirement.

Yes, custom manufacturing is available including non-standard diameters, face shapes (concave, convex, flat, double gauge), button shapes, and carbide grades such as Standard, Diamond, or Bluemaxx, allowing bits to be tailored to specific rock formations and drilling equipment.

Mining drill bits typically use tungsten carbide buttons in Standard, Diamond, or Bluemaxx grades. Diamond and Bluemaxx grades offer enhanced wear resistance and extended service life in highly abrasive hard rock formations compared to standard carbide options.

Selection depends on rock formation hardness, required hole diameter, drilling method (DTH, rotary, or cable tool), and rig compatibility. Our technical sales team, with over 100 years of combined drilling experience, can help match the right bit type and specifications to your project.

Our drill bits are manufactured under an ISO 9001:2015 certified quality management system, and select products meet API connection standards, ensuring consistent performance, dimensional accuracy, and compatibility with industry-standard drilling equipment.
