3M 7000120579 Scotch-brite Hs-dc Non-woven Disc 3 Inch

Product Description

The 3M 7000120579 is a Scotch-Brite High Strength HS-DC non-woven abrasive disc designed for general-purpose surface preparation on metal. Built on a durable open-web construction, it resists loading and runs cool, which keeps the aluminum oxide abrasive cutting consistently from first use to last. Common tasks include deburring, denibing, defuzzing, cleaning, and producing satin finishes on fabricated metal parts. At 3 inches in diameter with a 1/4-inch arbor mount, it fits standard die grinders and right-angle tools used in metal fabrication, HVAC sheet metal work, and light industrial maintenance.

This disc is suited for shops and field technicians working on a wide variety of metal surfaces where consistent finish quality and extended disc life are priorities. The conformable web follows contours without gouging, and the wear-resistant edge helps maintain uniform results across the working area. Discs can be stacked to cover larger surface areas or to increase cut aggressiveness, making this a flexible option across multiple surface prep applications in both residential and light commercial settings.

Key Features

• Open-web non-woven construction resists loading and runs cool for consistent cut rate throughout disc life
• Aluminum oxide abrasive handles deburring, denibing, defuzzing, and cleaning on metal surfaces
• Conformable disc body follows contours; wear-resistant edge delivers uniform finishes
• Stackable design allows expanded coverage or increased aggressiveness without changing tooling
• Tough non-woven material supports heavy-duty repeated use

Compatibility

Designed for use with die grinders and right-angle tools accepting a 1/4-inch arbor mount. Fits standard 3-inch disc applications in metal fabrication and surface preparation workflows.

Installation Notes

Installation and disc changes should be performed with the tool unplugged or air supply disconnected. Ensure the arbor nut is properly secured before operation. Always wear appropriate eye and face protection when operating abrasive discs. Follow tool manufacturer RPM ratings and do not exceed the maximum speed rating of the disc.
