3M 7000121101 Deburring Wheel 8 Inch Silicon Carbide Fine

Product Description

The 3M 7000121101 is a convolute deburring wheel designed for edge finishing, deburring, and surface blending on metal workpieces. Built with silicon carbide abrasive at a density of 9 and an extra hard density grade, it delivers consistent cutting action for fine finishing work. The wheel measures 8 inches in diameter with a 1-inch face width and a 3-inch center hole, and it is rated for a maximum of 4,500 RPM. It is installed by metalworkers and fabricators on backstand grinders, inline sanders, and manual backstands in production and job-shop environments.

This wheel is suited for deburring and finishing ferrous and non-ferrous metals where a fine surface finish is required. The convolute construction provides a controlled, uniform cut throughout the wheel's life. Compatible tooling includes backstands, inline sanders, and manual backstands. Mandrel and adapter compatibility is listed as adapter number 356. It is commonly used in metal fabrication shops, maintenance facilities, and manufacturing production lines where consistent deburring results are needed across high-volume runs or precision part finishing.
