Merit Abrasives 05539512519 Hook Loop Disc 50 Grit 5 in

Product Description

The MERIT ABRASIVES 05539512519 is a 5-inch hook and loop abrasive disc designed for surface preparation, blending, and finishing applications. Built with aluminum oxide abrasive in a non-woven construction, this coarse-grade disc operates at up to 11,000 RPM and delivers consistent, aggressive material removal. Its brown, flexible disc body conforms to irregular surfaces, making it a practical choice for metal finishing, paint removal, and prep work in fabrication or maintenance environments. Installers and tradespeople in HVAC fabrication, sheet metal, plumbing, and general maintenance will find this disc suited to demanding surface work.

This disc is intended for use with 5-inch hook and loop backing pad grinders and sanders. Its non-woven, flexible construction makes it effective on contoured and flat surfaces alike. The coarse 50-grit rating is appropriate for initial material removal, rust and scale stripping, and surface conditioning prior to welding or coating. No vacuum holes are included, so it is suited for open-face grinding and sanding tools without dust port requirements.
