Tru-maxx 66261109822 Deburring Wheel 4 Inch Silicon Carbide

Product Description

The TRU-MAXX 66261109822 is a unitized deburring wheel designed for edge finishing, light deburring, and surface blending on metal workpieces. Constructed with silicon carbide abrasive in a soft, fine-grade density 2 matrix, this wheel cuts aggressively enough to remove burrs while conforming to irregular contours without loading up. Rated to 8,500 RPM, it is sized at 4 inches in diameter with a 0.25-inch face width and a 0.25-inch center hole. Machinists, fabricators, and maintenance technicians reach for this wheel when cleaning up drilled holes, stamped edges, or welded seams before inspection or assembly.

This wheel is intended for use with die grinders, making it a practical bench or in-field tool for ferrous and non-ferrous metal finishing tasks. The unitized construction bonds the abrasive throughout the entire wheel body, so cutting action remains consistent as the wheel wears down. It is well-suited to production and repair applications in metalworking shops, manufacturing facilities, and general fabrication environments where controlled, repeatable edge treatment is required.

Key Features

• Silicon carbide abrasive provides sharp, consistent cut on hard metals and non-ferrous materials
• Density 2 soft grade matrix conforms to contours and reduces gouging risk
• Fine grade finish removes burrs without aggressive stock removal
• 8,500 RPM maximum speed rating compatible with standard die grinder operating ranges
• Unitized wheel construction delivers uniform performance throughout wheel life
• 0.25-inch center hole fits standard die grinder mandrels directly

Compatibility

Designed for use with die grinders. The 0.25-inch center hole accommodates standard die grinder arbors commonly found in professional metalworking and fabrication tooling.

Installation Notes

Installation and wheel changes must be performed with the die grinder disconnected from its power source. Verify that the spindle speed of the die grinder does not exceed the 8,500 RPM maximum rating of the wheel before operation. Inspect the wheel for cracks or damage before mounting and do not use any wheel that shows signs of deterioration. Always wear appropriate eye and face protection when operating abrasive wheels per ANSI B7.1 guidelines.
