The tool can be run by itself or as an integral component of the wellbore cleanup or displacement system. It features self-centering, nonrotational stabilizers to keep the nonrotating brush sleeve centered in the hole, preventing wear or damage to the casing. This ensures 360° brush coverage and eliminates uneven brush wear while allowing for rotation of the heavy-duty main mandrel in straight and high-angle holes. Another benefit is a special safety clutch that can be activated if the brush gets stuck. This allows torque to be transferred to the entire tool for working it free or washover contingencies if that becomes necessary. The tool is designed with ample circulation area to allow for high rate circulation and bypass of debris.
