Caprock Drill Bits

PDC bits use polycrystalline diamond compact cutters that shear rock through rotary motion, ideal for softer to hard formations with continuous cutting action. DTH hammer bits use tungsten carbide buttons and percussive impact energy delivered downhole, making them better suited for very hard, abrasive caprock and rock formations.

Diameters typically range from 2 inches to 18 inches for DTH hammer bits and 8 inches to 13.5 inches for PDC rock tools, with custom manufacturing available up to 48 inches for specialized project requirements outside standard offerings.

Yes. Infinity Tool MFG offers custom manufacturing including non-standard diameters, face shapes, button configurations, carbide grades, and blade counts. Their in-house engineering and drafting team designs bits tailored to specific formation hardness and drilling conditions.

Most PDC rock tools use API REG PIN connections such as 4-1/2" or 7-5/8" for compatibility with standard drilling equipment, while DTH hammer bits use shank types matching specific hammer models like QL40, DHD340, COP32, and Domintor 100.

In-stock items are typically dispatched within 2 working days from the Benton, Illinois manufacturing facility. Urgent or expedited shipments can be coordinated upon request, and custom-manufactured bits are shipped once fabrication and quality checks are complete.

Caprock drill bits are used in oil & gas exploration, water well drilling, geothermal energy development, mining, construction, and horizontal directional drilling (HDD) for utility, fiber, and pipeline installation, wherever hard or abrasive rock formations must be penetrated efficiently.
