HDD Reamers for Horizontal Directional Drilling for Sale

HDD reamers are available in a wide range of outside diameter and pilot combinations, with manufacturers like Infinity Tool MFG producing configurations from 1 inch up to 48 inches. Sizing is selected based on the target product pipe diameter, soil conditions, and the specific drill rig being used.

PDC reamers use fixed polycrystalline diamond compact cutters for shearing action, offering longer life and faster penetration in softer to medium formations. Tricone reamers use rotating roller cones with tungsten carbide buttons, better suited for harder, more abrasive rock formations where crushing action is required rather than shearing.

PDC reamers improve efficiency through controlled drilling fluid volume, symmetrical hole cutting from a centralized reamer design, and reduced chatter or fluctuating torque during operation. These design elements protect the diamond cutters from chipping and allow crews to ream from pilot to finished bore in a single pass on most jobs.

HDD reamers are engineered for a range of formations, from soft soil to hard rock, depending on cutter technology. PDC-cutter reamers excel in softer to medium formations, while hammer bit and tricone-style hole openers are built for hard rock and multi-formation drilling encountered in mining, geotechnical, and construction projects.

Most HDD reamers are manufactured with industry-standard shank connections, making them compatible with the majority of directional drill rigs on the market. It's still important to confirm shank type, thread specification, and pilot hole compatibility with your rig manufacturer or supplier before ordering to ensure a proper fit.

Selecting the right reamer depends on soil or rock formation type, target bore diameter, pilot hole size, and your drill rig's torque and shank specifications. Infinity Tool MFG's engineering team can help match a reamer configuration, including custom button layouts and diameter/pilot combinations, to your specific project conditions.
