3M 7100122432 Scotch-brite Hs-dc Non-woven Disc 12 Inch

Product Description

The 3M 7100122432 is the Scotch-Brite HS-DC High Strength non-woven abrasive disc, designed for general-purpose surface finishing on metal and similar substrates. Built on a durable open-web construction, this 12-inch disc uses aluminum oxide abrasive to clean, deburr, denib, defuzz, and produce consistent satin finishes. The open-web structure resists loading and dissipates heat during use, allowing the abrasive to cut at a consistent rate from first use to end of disc life. Licensed HVAC, plumbing, and mechanical trades rely on tools like this disc for prepping metal surfaces before brazing, welding, or coating applications.

This disc is suited for light to heavy-duty surface preparation across a wide range of metals including steel, aluminum, and stainless steel. The conformable disc body follows surface contours for even contact, and the wear-resistant edge helps maintain consistent finish quality across the full service life of the disc. Multiple discs can be stacked to increase aggressiveness or to cover larger surface areas in a single pass, making this format efficient for production and service environments alike.

Key Features

• Open-web non-woven construction resists loading and runs cool for consistent cut rate
• Aluminum oxide abrasive handles deburring, denibing, defuzzing, and cleaning on metal
• Conformable disc body with wear-resistant edge delivers uniform finishes
• 12-inch diameter with 3/4-inch arbor fits standard right-angle and disc grinders
• Discs can be stacked to increase cut aggressiveness or expand surface coverage
• Tough non-woven material supports heavy-duty repetitive use

Compatibility

Designed for use on standard disc grinders and finishing machines accepting a 12-inch non-woven abrasive disc with a 3/4-inch arbor mount.

Installation Notes

Mounting and disc changes should be performed with the grinder powered off and unplugged or locked out per applicable OSHA and shop safety procedures. Inspect the disc for damage before each use and confirm the arbor nut is properly seated and tightened before operation. Do not exceed the maximum RPM rating of the disc or the tool. Eye protection, gloves, and appropriate respiratory protection should be worn during grinding and finishing operations.
