3M 7000120993 Scotch-brite Roloc Disc 3 Inch Medium Grit

Product Description

The 3M 7000120993 is a Scotch-Brite Roloc non-woven abrasive disc designed for surface conditioning, blending, and finishing on all metal substrates. The disc measures 3 inches in diameter and uses aluminum oxide abrasive at a medium grit rating, making it effective for deburring, cleaning, and light material removal without aggressive stock loss. It operates at a maximum speed of 18,000 RPM and attaches via a TSM (Turn-and-Lock) quick-change hub, eliminating the need for separate adhesives or backup pads in compatible tool setups. Fabricators, welders, and metal finishing technicians are the primary users of this disc.

This disc is suited for surface prep and blending work on ferrous and non-ferrous metals in both shop and field environments. The non-woven construction conforms to irregular contours and weld seams, reducing the risk of gouging or undercutting. It is commonly used in HVAC sheet metal fabrication, structural steel prep, and general metalworking applications where a consistent, controlled finish is required. Each case contains 100 discs.

Installation Notes

Installation and disc changes should be performed with the tool unplugged or air supply disconnected. Verify the tool spindle speed does not exceed the 18,000 RPM maximum rated speed of the disc before operation. Secure the TSM hub fully by pressing and turning until locked before applying the disc to the work surface. Inspect the disc for damage or fraying before each use and discard any disc that shows signs of deterioration.
