3M 7000000691 Deburring Wheel Silicon Carbide Fine Grade

Product Description

The 3M 7000000691 is a unitized deburring wheel designed for light material removal, edge blending, and surface finishing on metal workpieces. Built with silicon carbide abrasive at a fine grade and density 2 soft construction, it delivers consistent cut with a smooth finish and minimal loading. The wheel measures 1.5 inches in diameter with a 0.25-inch face width and a 0.125-inch center hole, making it suited for use with small-diameter rotary tooling. Rated to 20,100 RPM, it handles the speeds generated by die grinders, inline sanders, and similar power tools. Machinists, fabricators, and metalworking technicians are the primary users.

This wheel is well suited for deburring drilled holes, blending weld seams, and cleaning up machined edges on ferrous and non-ferrous metals. Its compact size allows access to tight areas and internal bores where larger wheels cannot reach. The unitized construction maintains consistent performance throughout the wheel's life, unlike laminated or coated abrasive wheels that change character as they wear down. It is compatible with centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands.

Key Features

• Silicon carbide abrasive provides sharp, fast cutting action on hard metals and non-ferrous materials
• Fine grade with soft density 2 construction delivers smooth surface finish with light stock removal
• Unitized wheel design maintains consistent abrasive performance from full diameter to core
• Rated to 20,100 RPM for compatibility with standard die grinder and inline sander speeds
• Compact 1.5-inch diameter and 0.25-inch face width allow access to tight or recessed work areas
• Specification code 2SFIN identifies grade, density, and abrasive type for easy reorder matching

Compatibility

Compatible with centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands equipped with a 0.125-inch arbor.

Installation Notes

Installation is performed by metalworking technicians and machinists using standard rotary tooling. Before mounting, confirm the tool spindle speed does not exceed the 20,100 RPM maximum rating of the wheel. Secure the wheel firmly on the arbor using the appropriate collet or nut before starting the tool. Inspect the wheel for cracks or damage before each use and replace if any defects are found.
