3M 7000120814 | Scotch-Brite 5" Diameter SC-DN Medium Aluminum Oxide Surface Conditioning TN Quick Change Disc

Description

The 3M 7000120814 SC-DN is a 5.0" Scotch-Brite surface conditioning disc made for medium-grade metal finishing. This 3M Scotch-Brite 5" surface conditioning disc uses durable aluminum oxide mineral to deliver consistent cut and long service life. The SC-DN quick-change disc features a TN attachment for fast, tool-free disc changes on right-angle grinders and disc sanders. Non-woven open-web construction resists loading and continuously exposes fresh abrasive for predictable performance. The medium grade balances material removal and finish quality for refining, deburring, blending and radiusing tasks. Rated to operate at common industrial speeds up to 9,500 RPM, the disc performs reliably under production conditions. Maroon color coding simplifies grade identification on mixed shop floors and inventory racks. The SC-DN disc is optimized for nickel alloys yet performs well across a broad range of ferrous and non-ferrous metals. Flexible backing and conformability allow the disc to follow contours while minimizing undercutting. Standardizing on this 3M surface conditioning disc reduces rework and improves finish uniformity across operators. The disc’s construction supports cooler running and controlled stock removal during intermittent use. It integrates readily into manual and production finishing sequences as a dependable, medium-grade abrasive. Use the TN quick-change disc where frequent swaps and consistent finishing are part of the workflow. Store in a cool, dry environment to preserve adhesive and backing integrity and ensure a long shelf life. Follow 3M 7000120814 manufacturer mounting and safety guidance to achieve stated performance and operator protection.
