3M 7000121116 Deburring Wheel 8 in Silicon Carbide Density 9

Product Description

The 3M 7000121116 is a convolute deburring wheel engineered for aggressive surface conditioning and edge deburring on metal workpieces. Built with silicon carbide abrasive at a density grade of 9 (Extra Hard), this wheel delivers consistent stock removal and a fine finish in demanding production environments. It measures 8 inches in diameter with a 2-inch face width and a 3-inch center hole, running at a maximum rated speed of 4,500 RPM. Metalworking shops, fabrication facilities, and maintenance technicians use this wheel for deburring, blending, and finishing operations on ferrous and non-ferrous metals.

This convolute wheel is suited for use on backstands, inline sanders, and manual backstands where controlled deburring and surface blending are required. The silicon carbide grain cuts aggressively on harder materials and non-ferrous metals including aluminum, brass, and titanium. The fine grade designation makes it appropriate for finish deburring passes where edge quality and surface consistency matter. It is compatible with mandrel and adapter number 356 for proper mounting on compatible spindle-driven equipment.

Key Features

• Silicon carbide abrasive with Extra Hard density grade 9 for consistent, repeatable deburring performance
• Fine grade for finish deburring and edge blending on metal components
• Convolute wheel construction maintains a consistent working surface as the wheel wears
• Rated to 4,500 RPM maximum for use on production backstand and inline sander equipment
• 3-inch center hole with mandrel compatibility for adapter number 356
• Compatible with backstands, inline sanders, and manual backstands

Compatibility

Compatible with backstands, inline sanders, and manual backstands. Designed for use with mandrel and adapter number 356. Verify spindle speed does not exceed the 4,500 RPM maximum rating before mounting.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety per ANSI B7.1 guidelines. Power down and lock out the machine before mounting or removing the wheel. Inspect the wheel for damage before each use and confirm the machine spindle speed does not exceed 4,500 RPM. Use the correct mandrel and adapter for the 3-inch center hole to ensure secure, concentric mounting.
