3M 7000120681 Deburring Wheel 3 in Aluminum Oxide Density 8

Product Description

The 3M 7000120681 is a unitized abrasive deburring wheel designed for edge blending, light deburring, and surface finishing on metal workpieces. Built with aluminum oxide abrasive at a density grade of 8 (hard), it delivers consistent stock removal on ferrous and non-ferrous metals without loading quickly. The wheel measures 3 inches in diameter with a 1/4 inch face width and a 3/8 inch center hole, running at a maximum rated speed of 18,100 RPM. It is installed and operated by machinists, tool and die technicians, and fabrication professionals who need reliable performance on power-fed or handheld abrasive tooling.

This deburring wheel is suited for use on centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. The coarse grade and hard density make it a practical choice for aggressive deburring of castings, stampings, and machined components in production shop environments. The unitized construction maintains wheel integrity throughout the service life, reducing the risk of fiber separation or uneven wear during extended use cycles.

Key Features

• Aluminum oxide abrasive construction for consistent cut rate on steel, stainless, and non-ferrous metals
• Density grade 8 hard construction provides firm contact and stable wheel geometry under pressure
• Coarse grade for aggressive deburring and edge blending applications
• Maximum rated speed of 18,100 RPM for compatibility with high-speed rotary tooling
• 3/8 inch center hole fits standard arbors on die grinders and backstand equipment
• Unitized wheel design resists loading and maintains shape through the service life

Compatibility

Compatible with centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. The 3/8 inch center hole fits standard arbors on these tool types. Specification code 8ACRS confirms abrasive type, density, and grade per wheel marking standards.

Installation Notes

Always verify the spindle speed of the tool does not exceed the 18,100 RPM maximum rating before mounting. Power down and lock out the tool before installing or removing the wheel. Inspect the wheel for cracks or damage before each use and do not operate a damaged wheel. Follow ANSI B7.1 and applicable shop safety standards for abrasive wheel mounting and guarding.
