3M 7100358884 Abrasive Disc 5 Inch 120 Plus Grit

Product Description

The 3M 7100358884 is a 5-inch diameter Scotch-Brite HD-DN Precision Heavy Duty abrasive disc rated at 120 plus grit (CRS grade). It combines Scotch-Brite nonwoven fibers with 3M Precision-Shaped Grain in a single disc, creating an open three-dimensional structure that continuously exposes fresh abrasive as the disc wears. This design delivers consistent cut and finish throughout the disc's service life. The TN Quick Change attachment system allows fast spindle changes without tools. Fabricators, weld shops, and metal finishing technicians working on aluminum, mild steel, nickel alloy, and copper are the primary users of this disc.

This disc is suited for heavy-duty surface conditioning tasks including grinding, deburring, edge breaking, blending, and refining on ferrous and non-ferrous metals. The 120 plus grit CRS grade targets general-purpose material removal and surface prep on mild steel and comparable metals. It is sold individually and sized for 5-inch quick-change angle grinders and disc grinders commonly used in fabrication and maintenance environments. Multiple grades are available in the same product family: MED (150 plus), CRS (120 plus), XCRS (80 plus), and XXCRS (60 plus).

Installation Notes

Disc mounting and removal should be performed with the grinder powered off and unplugged or locked out per site lockout/tagout procedures.
