Trusted Air Rock Drilling Company

Air drilling uses compressed air instead of liquid drilling fluid to clear cuttings from the borehole and power certain down-the-hole hammer systems. The air lifts rock fragments to the surface while helping keep the bit engaged with the formation. This method can improve penetration in suitable ground conditions, reduce fluid handling needs, and support efficient rock drilling when matched with the right bit and tooling.

Common rock drilling techniques include rotary drilling, down-the-hole hammer drilling, top hammer drilling, cable tool drilling, tricone drilling, and directional drilling. The best method depends on formation hardness, bore size, depth, required accuracy, and whether the job involves waterwell, geothermal, mining, construction, HDD, or oil and gas work. Tool selection is critical for penetration rate, stability, and tool life.

DTH hammer bits are often used for air rock drilling because compressed air drives the hammer while also clearing cuttings from the hole. Infinity Tool MFG manufactures DTH bits in multiple diameters, face shapes, and shank options. Proper bit selection should consider formation type, desired bore diameter, hammer compatibility, air volume, and expected wear conditions.

Yes. Infinity Tool MFG offers custom PDC bits, custom PDC reamers, and custom hole openers. Customers can specify diameter, thread connection, blade count, nozzle design, ground conditions, quantity, and other application details. The in-house engineering and drafting team can help translate project requirements into practical tooling designs for drilling, reaming, or specialized applications.

PDC bits use polycrystalline diamond compact cutters and are often selected for efficient shearing action in suitable formations. Tricone bits use rotating cones with cutting structures that crush and gouge rock. PDC bits can offer strong performance in many softer to medium formations, while tricone bits remain useful in varied drilling conditions where roller cone action is preferred.

A hole opener enlarges an existing pilot bore to a larger finished diameter. Infinity Tool MFG manufactures Tricone Hole Openers, DTH Hole Openers, and custom options for different drilling applications. Hole openers are commonly used when a pilot hole provides guidance, and the final bore must be expanded efficiently while maintaining centralization and stable cutting action.

Bit repair can be worthwhile when the tool body remains serviceable and refurbishment can restore useful performance at a lower cost than replacement. Infinity Tool MFG offers bit repair services for customers who want to extend tool life. The best repair approach depends on wear patterns, cutter or button condition, thread integrity, and the drilling environment that caused the damage.

Infinity Tool MFG supports oil and gas, geothermal and waterwell, construction, horizontal directional drilling, mining, aerospace and defense, and medical device manufacturers. For drilling customers, the company manufactures PDC bits, DTH bits, drag bits, reamers, hole openers, and specialty tools designed to address different bore sizes, ground conditions, and performance expectations across demanding applications.
