3M 7100009310 Scotch-brite Roloc Disc 3 Inch Coarse

Product Description

The 3M 7100009310 is a Scotch-Brite Roloc light grinding and blending disc designed for weld grinding and surface blending on mild steel. Built with a ceramic aluminum oxide abrasive grain blend, it delivers a high cut-rate while maintaining the ability to blend and refine in a single pass. The disc is rated for a maximum speed of 18,000 RPM and measures 3 inches in diameter. It is commonly installed and used by metalworkers, fabricators, and maintenance technicians who need to address weld beads and surface imperfections without switching between multiple abrasive products.

This disc is suited for light grinding and blending applications on mild-steel workpieces. It is engineered to effectively blend and refine a grade 36 scratch or finer, making it appropriate for multi-step finishing workflows where reducing finishing time is a priority. The Scotch-Brite non-woven material construction resists melting on hot welds, allowing blending work to proceed immediately after welding without waiting for the workpiece to cool. The 3M Roloc quick-change attachment system allows fast disc swaps during multi-step processes.

Installation Notes

Installation and operation of abrasive discs should be performed by qualified technicians familiar with angle grinder and die grinder safety practices. Always verify the tool's maximum RPM rating meets or exceeds the disc's 18,000 RPM rating before mounting. Inspect the disc and backup pad for damage before each use and ensure the Roloc attachment is fully engaged before operating. Always wear appropriate personal protective equipment including eye protection and gloves when operating abrasive products.
