Rock Drill Bits for Sale

PDC bits with polycrystalline diamond compact cutters are generally considered best for drilling stone due to their durability and cutting efficiency in hard, abrasive materials. For deeper stone formations, DTH hammer bits with tungsten carbide buttons provide the percussive force needed for efficient penetration and hole stability.

A rock drill bit is a specialized cutting tool attached to a drill string that bores through hard and abrasive rock formations. Infinity Tool MFG's line includes PDC bits, DTH hammer bits, tricones, drag bits, and cable tool bits, each engineered with different cutting mechanisms (rotary shearing, percussive impact, or roller cone crushing) to deliver reliable penetration for oil & gas, mining, water well, geothermal, and construction drilling applications.

Rock drill bits are available across a wide diameter range, from approximately 2 inches up to 18 inches for DTH hammer bits, and 8 to 13.5 inches for PDC water well rock tools, with custom manufacturing available for non-standard diameters to fit specific rig and application requirements.

PDC bits use fixed polycrystalline diamond cutters and rely on rotary shearing action, making them efficient in continuous drilling through hard and abrasive formations. DTH hammer bits use tungsten carbide buttons and a pneumatic hammer mechanism to deliver percussive impact, which is more effective in very hard rock and deep vertical holes.

Yes, custom manufacturing is available for face shapes, button configurations, carbide grades, connection types, and diameters. This allows drilling contractors to specify bits engineered precisely for their formation type, rig compatibility, and application, whether for oil & gas, mining, geothermal, water well, or HDD projects.

The product range covers soft, medium, hard, and abrasive rock formations. Drag bits and tricones are suited to soft-to-medium formations, while PDC and DTH hammer bits are engineered for hard and abrasive rock, giving contractors versatile options across nearly all formation types encountered in the field.

These rock drill bits support oil & gas exploration and production drilling, mining and construction projects requiring efficient hard rock penetration, water well and geothermal drilling using PDC and cable tool bits, and horizontal directional drilling (HDD) where directional hammer and drag bits guide pilot holes through rock for underground utility and pipeline installation.
