Quick-Change Sanding Discs for Metalwork

The 3M 361F Quick Change Disc uses aluminum oxide abrasive on a polyester YF-weight backing to deliver coarse 60-grit material removal. A TR quick-change system locks each 2-inch disc onto compatible backup pads for fast swaps during grinding or blending tasks. The closed-coat construction resists loading when working on steel or stainless surfaces. Maximum operating speed is rated at 20,000 RPM for high-speed right-angle tools.

Polyester Backing and TR Mount for Shop Durability

Heat-resistant properties let the disc withstand sustained contact without premature breakdown. The orange color identifies the 361F series at a glance on a busy bench. A 50-piece package keeps replacements on hand for production runs or multi-shift operations. The TR attachment implies a twist-lock motion that secures the disc without tools.

Fifty-Pack Supports Continuous Production

Bulk quantity reduces reorder frequency for fabrication shops and maintenance teams. Coarse grit targets weld grinding, deburring and heavy stock removal rather than fine finishing. Aluminum oxide cuts consistently on ferrous metals without the cost of ceramic alternatives. No additional accessories or software are included with this abrasive-only product.
