Merit Abrasives 05539512525 7 in Aluminum Oxide Hook Loop Disc

Product Description

The MERIT ABRASIVES 05539512525 is a 7-inch non-woven hook and loop abrasive disc designed for surface preparation, blending, and finishing applications. The disc uses aluminum oxide abrasive material in a coarse grade, making it well suited for aggressive stock removal, rust and scale removal, and surface conditioning on metal and wood substrates. Its flexible, non-woven construction conforms to contoured surfaces, allowing consistent contact across irregular profiles. Weighing approximately 0.5 pounds per unit, this disc is a direct one-for-one replacement in standard 7-inch random orbit and angle grinder setups equipped with hook and loop backing pads.

This abrasive disc is used in metal fabrication shops, automotive body work, woodworking, and general industrial surface prep. The coarse grade is appropriate for initial material removal, weld blending, and paint or coating stripping. The hook and loop attachment system allows fast disc changes without adhesive, reducing downtime during production work. Trades that commonly use this disc include metalworkers, fabricators, auto body technicians, and maintenance professionals requiring a durable, flexible abrasive for coarse-duty surface work.

Key Features

• 7-inch diameter fits standard hook and loop backing pads for random orbit and angle grinder tools
• Aluminum oxide abrasive material provides consistent cutting action on metal and wood surfaces
• Coarse grade rating for aggressive stock removal and initial surface conditioning
• Non-woven flexible construction conforms to curved and irregular surfaces
• Hook and loop attachment system enables tool-free, quick disc changes

Compatibility

Designed as an OEM-style replacement for 7-inch hook and loop non-woven abrasive discs used with standard random orbital sanders and angle grinders equipped with hook and loop backing pads.

Installation Notes

Installation is performed by pressing the disc firmly onto a compatible 7-inch hook and loop backing pad until fully seated. Ensure the tool is powered off and unplugged or the air supply is disconnected before changing discs. Inspect the backing pad for wear or damage prior to mounting a new disc, as a worn pad reduces holding force and can cause disc separation during operation. Always wear appropriate eye protection and follow applicable workplace safety standards when operating abrasive tools.
