3M 7000045856 Deburring Wheel Silicon Carbide Unitized

Product Description

The 3M 7000045856 is a unitized deburring wheel designed for material removal, surface blending, and edge finishing on metal workpieces. Built with silicon carbide abrasive at a very coarse grade and density 7 construction, this wheel delivers aggressive cutting action while maintaining consistent stock removal throughout its life. The unitized construction bonds abrasive grains throughout the wheel body, so performance stays stable as the wheel wears. It measures 3 inches in diameter with a 0.5 inch face width and accepts a 0.25 inch center arbor. Rated to 14,100 RPM, it is well suited for high-speed power tools used in production and fabrication environments.

This wheel fits a broad range of metalworking applications including deburring cut edges, blending weld seams, and light surface conditioning on ferrous and non-ferrous metals. Compatible tooling includes centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. Its compact 3 inch diameter makes it a practical choice for inline and handheld die grinder setups where access to tight geometries is required. Metalworking shops, fabricators, and maintenance technicians are the typical end users.

Installation Notes

Installation is typically performed by a machinist, fabricator, or maintenance technician. Before mounting, confirm the tool spindle speed does not exceed the 14,100 RPM rating marked on the wheel. Power down and disconnect the tool from its power source before changing wheels. Inspect the wheel for cracks or damage prior to each use and never operate a damaged or out-of-round wheel.
