Weiler 51523 Hook Loop Abrasive Disc 7 in Aluminum Oxide Coarse

Product Description

The WEILER 51523 is a 7-inch hook and loop non-woven abrasive disc designed for surface conditioning, blending, and finishing on metal substrates. It uses an aluminum oxide abrasive in a coarse grade, making it effective for aggressive material removal and surface prep work. The non-woven construction allows the disc to conform to irregular surfaces while maintaining consistent cut throughout the disc's life. Rated to 6000 RPM, it is sized for standard 7-inch random orbital and disc sanders used in metal fabrication and maintenance environments. The disc attaches and releases quickly via the hook and loop backing system, reducing changeover time during production work.

This disc is suited for use on aluminum and stainless steel surfaces where coarse surface conditioning or weld blending is required. Typical applications include deburring, blending weld seams, removing mill scale, and preparing surfaces before coating or inspection. It is well-suited for sheet metal shops, structural fabrication, and maintenance repair operations handling non-ferrous and ferrous metals.

Key Features

• 7-inch diameter fits standard hook and loop backing pads for random orbital sanders
• Aluminum oxide abrasive in coarse grade for aggressive surface conditioning
• Non-woven construction conforms to contours and provides consistent cut rate
• Rated to 6000 RPM for safe operation on compatible tools
• No vacuum holes — compatible with solid backing pads
• Brown disc color for easy grade identification during multi-disc operations

Compatibility

Designed for use on aluminum and stainless steel. Attaches to 7-inch hook and loop backing pads on random orbital sanders and disc grinders rated for non-woven abrasive discs up to 6000 RPM.

Installation Notes

Confirm the backing pad RPM rating meets or exceeds the disc rating before mounting. Ensure the sander or grinder is powered off and unplugged before attaching or removing the disc. Press the disc firmly onto the hook and loop pad to ensure full contact before operating. Inspect the disc and backing pad for wear or damage before each use.
