3M 7000120749 Deburring Wheel 8 in Silicon Carbide Fine

Product Description

The 3M 7000120749 is a unitized deburring wheel designed for edge blending, light deburring, and surface finishing on metal workpieces. It is built with silicon carbide abrasive in a soft, fine-grade density 2 construction, which delivers consistent cut rate and finish quality across the wheel's full face. Unitized wheels compress under load and self-dress during use, maintaining a uniform cutting surface without requiring dressing tools. This wheel is rated to a maximum of 4,000 RPM and weighs 1.81 pounds. It is installed and operated by machinists, tool and die technicians, and metal fabricators working on bench-mounted or powered abrasive equipment.

This wheel fits centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands, making it suitable for both production and maintenance finishing applications. The 8-inch diameter and 0.5-inch face width target standard arbor-mount setups in metal fabrication shops, job shops, and manufacturing facilities. It is appropriate for ferrous and non-ferrous metals where a fine, consistent surface finish is required without aggressive stock removal.

Key Features

• Silicon carbide abrasive delivers sharp, consistent cutting action on metal surfaces
• Density 2 soft-grade unitized construction compresses under load for self-dressing performance
• Fine grade finish suitable for edge blending and light deburring without heavy stock removal
• 4,000 RPM maximum rating compatible with common powered backstands and grinders
• 8-inch diameter with 0.5-inch face width fits standard 1-inch center hole arbor mounts
• Compatible with a broad range of powered abrasive tooling platforms used in production environments

Compatibility

Designed for use with centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands equipped with a 1-inch arbor. Verify that the spindle speed of the host machine does not exceed 4,000 RPM before mounting.

Installation Notes

Installation should be performed by a qualified machinist or abrasive equipment operator following the machine manufacturer's mounting instructions. Power down and lock out the machine before mounting or removing the wheel. Confirm arbor size matches the 1-inch center hole and that the rated machine spindle speed does not exceed the wheel's 4,000 RPM maximum. Inspect the wheel for damage before each use and do not exceed the stated speed rating under any operating condition.
