3M 7000120949 Scotch-brite Hs-dc Non-woven Disc 6 in

Product Description

The 3M 7000120949 is a Scotch-Brite High Strength HS-DC non-woven abrasive disc engineered for general-purpose surface conditioning on metal workpieces. Built on a durable, open-web nylon construction with aluminum oxide (AO) abrasive, the disc resists loading and runs cool, which keeps the abrasive cutting at a consistent rate from the first use through the end of disc life. At 6 inches in diameter with a 1/2-inch arbor hole, it mounts directly to standard disc grinders and right-angle tools. Machinists, fabricators, and finishing technicians use it to deburr, denib, defuzz, clean, and produce satin finishes on ferrous and non-ferrous metals.

This disc is suited for metal fabrication shops, production finishing lines, and maintenance applications where consistent surface texture is required. The conformable web follows irregular contours, making it effective on curved or profiled workpieces as well as flat stock. Because the disc can be stacked, operators can expand cutting action or cover larger surface areas without changing tooling. Typical applications include weld cleanup, pre-paint prep, and general deburring on sheet metal, tubing, and machined components.

Key Features

• Open-web aluminum oxide construction resists loading and maintains cut rate throughout disc life
• Conformable disc with wear-resistant edge delivers consistent finishes on flat and contoured surfaces
• 6-inch diameter with 1/2-inch arbor fits standard right-angle grinders and disc tools
• Discs can be stacked to increase aggressiveness or cover larger surface areas
• Non-woven material runs cool, reducing heat buildup and workpiece distortion risk
• Suitable for deburring, denibing, defuzzing, cleaning, and satin finishing on a wide variety of metals

Compatibility

Designed as a replacement or standard-use disc for right-angle grinders and disc finishing tools accepting a 6-inch diameter disc with a 1/2-inch arbor hole.

Installation Notes

Installation is performed by grinding equipment operators and metal fabrication technicians. Before mounting, power down and disconnect or lock out the grinder per OSHA lockout/tagout procedures. Verify the tool's rated RPM meets or exceeds the disc's rated speed before operation. Inspect the disc for damage before each use and do not operate a disc that shows tears, unraveling, or deformation.
