Diamond Reamers Coated Single-Pass

A single-pass diamond reamer can take a pilot hole straight to finish bore diameter in one run, eliminating the need for multiple passes that standard drill bits often require. This reduces rig time, controls drilling fluid volume, minimizes torque fluctuations, and its centralized, symmetrical cutter design distributes cutting forces evenly to produce a more stable, round borehole and extend the life of the cutting structure.

These reamers feature Polycrystalline Diamond Compact (PDC) cutting surfaces, which combine synthetic diamond layers bonded to a tungsten carbide substrate. This coating technology provides exceptional wear resistance and hardness, protecting the diamonds from chipping and breaking even in hard rock and abrasive formations.

Yes, Infinity Tool MFG's PDC reamers are specifically engineered with a tapered and spiral cutter layout that allows them to ream from the pilot hole straight to the finished bore diameter in the majority of drilling applications, significantly reducing overall drilling cycle time compared to multi-pass methods.

Infinity Tool MFG manufactures reamers and drilling tools ranging from 1 inch to 48 inches in diameter, with a wide variety of button configurations and outside diameter/pilot combinations available to match specific borehole and formation requirements across multiple drilling applications.

Single-pass PDC reamers are compatible with Down-The-Hole (DTH) drilling, rotary drilling, and Horizontal Directional Drilling (HDD) methods. They are also designed to work with industry-standard shanks, making them adaptable across most rotary and DTH drilling rig setups used in the field.

The centralized, symmetrical cutter design of PDC reamers distributes cutting forces evenly around the bore, which minimizes chatter and fluctuating torque during operation. This symmetrical hole-cutting action results in a more stable, round borehole and extends the working life of the cutting structure.

Single-pass diamond reamers are widely used in oil and gas drilling, mining and geotechnical exploration, water well drilling, and construction and foundation work. Their durability and hole-enlargement efficiency also make them suitable for horizontal directional drilling (HDD) in utility installation projects.
