3M 7000121102 Deburring Wheel 8 Inch Silicon Carbide

Product Description

The 3M 7000121102 is a convolute deburring wheel engineered for consistent surface finishing and edge deburring on metal workpieces. Built with silicon carbide abrasive in a fine grade, hard density construction, it delivers controlled cutting action without aggressive stock removal. The wheel measures 8 inches in diameter with a 1-inch face width and a 3-inch center hole, and it is rated to a maximum of 4,500 RPM. Metalworkers, fabricators, and industrial maintenance technicians install this wheel on backstands and inline sanders to clean up burrs, sharp edges, and light surface irregularities left after machining or cutting operations.

This deburring wheel is suited for light to medium deburring, blending, and surface conditioning tasks in metal fabrication shops, maintenance environments, and production finishing lines. The convolute construction provides consistent performance throughout the life of the wheel. Compatible tooling includes backstands, inline sanders, and manual backstands. The 3-inch center hole fits mandrel and adapter number 356, making mounting straightforward on equipment already configured for that adapter type.

Key Features

• Silicon carbide abrasive material for effective deburring on ferrous and non-ferrous metals
• Fine grade, hard density convolute construction for controlled cutting and consistent wear
• 8-inch diameter with 1-inch face width for broad contact coverage
• 4,500 RPM maximum rated speed for safe use on standard backstand and inline sander equipment
• 3-inch center hole with mandrel/adapter compatibility for number 356
• Compatible with backstands, inline sanders, and manual backstands

Compatibility

Designed for use with backstands, inline sanders, and manual backstands. Fits mandrel and adapter number 356. Verify machine RPM rating meets or exceeds 4,500 RPM before mounting.

Installation Notes

Installation should be performed by a qualified technician familiar with abrasive wheel safety. Power down and lockout/tagout the machine before mounting or removing the wheel. Confirm the spindle speed of the machine does not exceed the 4,500 RPM maximum rating of this wheel before operation. Inspect the wheel for damage prior to each use and ensure the adapter is properly seated and secured according to the equipment manufacturer's guidelines.
