Rock Drill Bits: Carbide, Button & Cross Types

For hard stone and rock formations, tungsten carbide button DTH hammer bits or PDC bits with diamond-enhanced carbide typically perform best. DTH hammer bits use percussive impact to break through hard, abrasive rock efficiently, while PDC bits offer smooth rotary cutting action. The right choice depends on rock hardness, formation type, and available drilling equipment.

DTH (Down-The-Hole) hammer bits use tungsten carbide buttons and percussive impact to break hard, abrasive rock, making them ideal for mining and water well applications. PDC bits use polycrystalline diamond compact cutters for a shearing rotary action, offering faster penetration in softer to medium formations and versatility across water well, HDD, and oil & gas drilling.

Infinity Tool MFG offers Standard, Diamond, and Bluemaxx carbide grades for DTH hammer bit buttons. Diamond and Bluemaxx grades provide enhanced wear resistance and extended service life in highly abrasive or hard rock formations, while Standard carbide suits general-purpose drilling. Button shapes include Domed, Ballistic, and Semi-Ballistic to match specific formation and application needs.

Yes, Infinity Tool MFG offers custom manufacturing for non-standard diameters, face shapes, button configurations, carbide grades, and connection types. Their in-house engineering and CNC manufacturing capabilities in Benton, Illinois allow for tailored bit designs to meet unique drilling conditions, unusual hole sizes, or specialized equipment requirements not covered by standard catalog offerings.

DTH hammer bits are available from 2" to 18" (50.8mm to 457.2mm) in diameter, with 12 distinct shank and connection models including Domintor 100, MACH 20, COP32, DHD 340, QL40, and TD40, ensuring compatibility with virtually any standard DTH hammer drilling system used across mining, construction, and water well projects.

For water well drilling, PDC bits with polycrystalline diamond compact cutters and API REG PIN connections are commonly used for their efficient rock penetration across varied formations. DTH hammer bits with tungsten carbide buttons are preferred in hard rock conditions requiring percussive drilling, while cable tool bits suit traditional percussion drilling setups.
