3M 7100030739 Deburring Wheel 8 Inch Silicon Carbide

Product Description

The 3M 7100030739 is a unitized deburring wheel designed for surface finishing, deburring, and light blending operations on metal workpieces. Built with silicon carbide abrasive at a fine grade and soft density (Density 2), this wheel removes burrs and sharp edges without aggressive stock removal. At 8 inches in diameter with a 0.25 inch face width and a 0.5 inch center hole, it mounts directly to compatible spindle-driven equipment. Maximum rated speed is 4,000 RPM. Metalworking shops, fabricators, and finishing technicians use this wheel in production and job-shop environments where consistent, repeatable deburring results are required.

This wheel is suited for use on ferrous and non-ferrous metals where a fine, soft cutting action is preferred. The unitized construction binds abrasive fibers throughout the wheel body, so the cutting characteristics remain consistent as the wheel wears down. Compatible tooling includes centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. It is a single-piece unit sold individually. Typical applications include edge conditioning, surface blending, and light scale removal on machined or stamped parts.

• Fine grade, Density 2 (soft) construction delivers controlled deburring without aggressive material removal
• Unitized wheel design maintains consistent performance throughout the full life of the wheel
• 8 inch diameter with 0.25 inch face width and 0.5 inch center hole for standard spindle mounting
• Rated to 4,000 RPM maximum for use on common bench and inline driven equipment
• Compatible with centerless grinders, die grinders, inline sanders, and backstands

Compatibility

Designed for use with centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. Verify spindle speed does not exceed the 4,000 RPM maximum wheel rating before mounting.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety. Always confirm the spindle speed of the machine does not exceed the 4,000 RPM maximum rated speed of this wheel before mounting. Disconnect and lock out power to the machine before mounting or removing the wheel. Inspect the wheel for damage prior to each use and do not operate a wheel that shows cracks, chips, or uneven wear.
