3M 7000120988 Scotch-brite Abrasive Disc 6 Inch 1/4 Inch Arbor

Product Description

The 3M 7000120988 is a Scotch-Brite High Strength non-woven abrasive disc engineered for general-purpose surface finishing across a range of metalworking applications. Built on a durable open-web construction with aluminum oxide abrasive, this 6-inch disc mounts on a 1/4-inch arbor and is designed for use on angle grinders and disc sanders. The open-web structure resists loading and runs cooler than bonded abrasive alternatives, maintaining a consistent cut rate from first use through the end of disc life. Fabricators, welders, and metal finishing technicians rely on this disc for deburring, denibing, defuzzing, and achieving repeatable satin finishes on steel, aluminum, and similar substrates.

This disc suits residential shop environments and commercial fabrication settings alike. It performs well on tasks that require controlled material removal without aggressive stock loss, including edge cleanup after cutting, pre-paint surface prep, and weld spatter removal. The conformable disc body follows contours and irregular surfaces, making it practical for formed or curved workpieces. Multiple discs can be stacked on the arbor to increase face width and cover larger surface areas in a single pass, reducing setup time on flat stock finishing runs.

Key Features

• Durable non-woven open-web construction resists loading and extends usable disc life
• Aluminum oxide abrasive provides consistent cut rate on a wide variety of metals
• 6-inch diameter with 1/4-inch arbor fits standard angle grinders and disc sanders
• Conformable body with wear-resistant edge delivers uniform finishes on flat and curved surfaces
• Stackable design allows coverage of larger surface areas without changing tooling setup
• Runs cool to protect workpiece surface integrity and reduce heat-related distortion

Compatibility

Designed for use on angle grinders and disc sanders accepting a 6-inch diameter disc with a 1/4-inch arbor. Suitable for use on steel, aluminum, and similar metals in deburring, surface prep, and finishing applications.

Installation Notes

Mount the disc on a grinder or sander rated for the disc diameter and arbor size before connecting power. Always inspect the disc for damage before each use and confirm the tool RPM rating does not exceed the disc rating. Wear appropriate eye protection, gloves, and respiratory protection when grinding or finishing metal. Power down and disconnect the tool before changing or stacking discs.
