Description
The SMC 32-inch HDD Hole Opener (Rock Reamer) with IADC637G classification is purpose-built for trenchless drilling in hard rock formations. Designed for use in Horizontal Directional Drilling (HDD) applications, this reamer offers superior durability, torque handling, and cutting efficiency, even in the most abrasive and consolidated ground conditions.
Featuring high-grade tungsten carbide inserts and aggressive cutter geometry, the IADC637G reamer excels at enlarging pilot holes in granite, basalt, and other high-compression rock types. Its rugged body construction ensures structural integrity under heavy loads, while precision-engineered nozzles provide optimized fluid flow for cooling and cuttings removal.
With its 32-inch diameter, this rock reamer is ideal for large-diameter utility installations, including pipeline, telecom, and sewer crossings, where accuracy and reliability are critical. The API thread connection ensures easy compatibility with standard drill strings used in HDD operations.
Engineered for performance, the SMC HDD Hole Opener IADC637G delivers maximum cutting power, longer service life, and reduced downtime in challenging trenchless projects.
Application:
Hard formations for high compressive strength, such as sandstone, hard shale, dolomite, hard gypsum, chert, granite, etc.
