3M 7000120857 Scotch-brite Ld-dc Deburring Disc 6 Inch

Product Description

The 3M 7000120857 is a Scotch-Brite LD-DC light deburring and finishing disc designed for use on all types of metal. This non-woven abrasive disc features a very fine grade aluminum oxide (AO) mineral and a dense open-web construction that resists loading and runs cool during operation. The 6-inch diameter disc mounts via a 1/4-inch arbor and fits straight shaft tools and bench motors. It is used by machinists, fabricators, and finishing technicians who need consistent, controlled surface conditioning without altering workpiece geometry.

This disc is suited for lightweight deburring, surface cleaning, and finishing on ferrous and non-ferrous metals in both shop and production environments. The moderately conformable web allows it to follow contours without cutting aggressively into the base material. Discs can be used individually or stacked on a straight shaft tool or bench motor to create a wider cleaning edge, making it practical for edge blending and light scale removal across flat and shaped workpieces.

Key Features

• Very fine grade AO mineral for lightweight deburring, cleaning, and surface finishing
• Open-web construction resists loading and dissipates heat for consistent finishes
• Non-woven construction conditions surfaces without changing workpiece geometry
• Can be used individually or stacked for a broader cleaning edge
• Compatible with bench motors and straight shaft tools via 1/4-inch arbor
• Dense web design provides extended service life under repeated use

Compatibility

Designed for use with bench motors and straight shaft tools accepting a 1/4-inch arbor. Suitable for use on all metal types including ferrous and non-ferrous materials.

Installation Notes

Installation is performed by machinists or finishing technicians familiar with abrasive disc tooling. Power down and disconnect the tool from its power source before mounting or removing the disc. Ensure the arbor nut is secured before operating the tool, and verify the tool spindle speed does not exceed the rated maximum for the disc. Wear appropriate PPE including eye protection and gloves during operation.
