3M 7000046145 Convolute Deburring Wheel 8 Inch Fine Grit

Product Description

The 3M 7000046145 is a convolute-constructed deburring wheel built for consistent edge deburring and burr removal on metal workpieces. The wheel uses a non-woven web construction layered around a core, producing a hard, dense structure that maintains its profile throughout its service life. A specially engineered resin system resists heat buildup and smearing, which reduces prep and cleanup time between operations. At 8 inches in diameter and 2.5 inches wide, this Fine grit wheel suits bench grinder and pedestal grinder setups used in fabrication, maintenance, and metalworking applications. It is installed and operated by machinists, tool and die technicians, and industrial maintenance professionals.

This wheel is designed for applications where edge retention is critical. Convolute construction gives it a balanced, smooth run from first use to the end of its life, making it reliable for high-volume deburring on production lines or repetitive maintenance tasks. The non-woven abrasive web runs cooler than bonded abrasive alternatives, which reduces the risk of heat damage on heat-sensitive base materials. It performs best when consistently presented with sharp edges or defined metal burrs rather than broad surface stock removal.

Installation Notes

Installation should be performed by a qualified operator following the grinder manufacturer's mounting instructions and applicable ANSI B11 or OSHA 29 CFR 1910.215 guarding requirements. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for damage before installation and verify the machine's rated RPM does not exceed the wheel's maximum operating speed. Use proper flanges and blotters as specified by the grinder manufacturer.
