Infinity Tool MFG manufactures rock drilling tools, including PDC drill bits and reamers. The company has produced PDC drill bits for more than 10 years for a range of drilling applications including oil and gas, geothermal, water wells, construction, horizontal directional drilling (HDD) and mining. PDC bit diameters range from 3¾ inches up to 18 inches. PDC Reamers are designed with a taper and a spiral. The taper is to centralizes the reamer in the pilot hole to ensure a symmetrical hole is cut, equalize the size of the cut and support reaming from pilot to finish bore.
