3M 7000046243 Silicon Carbide Deburring Wheel 8 Inch

Product Description

The 3M 7000046243 is a convolute deburring wheel designed for edge finishing, burr removal, and surface blending on metal workpieces. Built with silicon carbide abrasive in a hard, fine-grade density, it delivers consistent cutting action and controlled material removal across a range of ferrous and non-ferrous metals. The wheel measures 8 inches in diameter with a 1-inch face width and a 3-inch center hole, and it is rated for operation up to 4,500 RPM. It weighs 1.3 pounds and is sold individually. Metalworking professionals and fabricators rely on this wheel for finishing operations that require uniform surface quality without aggressive stock removal.

This deburring wheel is suited for use on backstands, inline sanders, and manual backstands in fabrication shops and production environments. It is compatible with mandrel and adapter number 356. Typical applications include deburring drilled or punched holes, edge radiusing, and light surface conditioning on sheet metal, tubing, and structural components. It performs well in both manual and machine-driven finishing setups where consistent abrasive contact and wheel integrity at elevated spindle speeds are required.

Installation Notes

This wheel must be installed and operated by a qualified metalworking professional familiar with abrasive wheel safety. Always power down and de-energize the machine before mounting or removing the wheel. Confirm that the machine spindle speed does not exceed the 4,500 RPM maximum rating, and inspect the wheel for cracks or damage before each use. Follow ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels.
