Merit Abrasives 05539512518 Hook Loop Disc 80 Grit 5 in

Product Description

The MERIT ABRASIVES 05539512518 is a 5-inch hook-and-loop abrasive disc designed for surface preparation, blending, and finishing applications. Built with a non-woven aluminum oxide construction, this disc delivers consistent medium-grade cutting action at 80 grit across a flexible, conformable backing that follows contoured and irregular surfaces. Rated to 11,000 RPM, it attaches and releases quickly on any hook-and-loop backup pad, reducing changeover time during high-volume work. The red non-woven material resists loading and maintains an open structure longer than coated abrasive alternatives, making it a reliable choice for metal, composite, and painted surface work.

This disc is suited for use in residential and light commercial trade environments where surface prep, rust removal, weld blending, paint scuffing, or finishing passes are part of routine workflow. HVAC sheet metal fabricators, plumbers prepping pipe surfaces, and general contractors use non-woven hook-and-loop discs like this in angle grinder and random orbital applications. The flexible disc conforms to curved tubing, sheet metal flanges, and irregular substrates without gouging or leaving deep scratch patterns. Sold individually, with a minimum order quantity of 100 units per order.

Key Features

• 80 grit medium-grade aluminum oxide abrasive for controlled material removal and surface blending
• Non-woven open-web construction resists loading and maintains cutting performance across the disc life
• Flexible backing conforms to curved, contoured, and irregular workpiece surfaces
• Hook-and-loop attachment for fast disc swaps on compatible backup pads
• 11,000 RPM maximum speed rating for use with standard angle grinders and random orbital tools
• No vacuum holes, keeping the disc profile simple and compatible with solid backup pads

Compatibility

Designed for use with 5-inch hook-and-loop backup pads on angle grinders and random orbital sanders rated to 11,000 RPM or lower. No specific OEM system compatibility is stated by the manufacturer for this disc.

Installation Notes

This disc is installed by a technician or trades professional using a compatible 5-inch hook-and-loop backup pad mounted to an angle grinder or random orbital sander. Confirm the tool RPM rating meets or exceeds 11,000 RPM before mounting the disc. Inspect the disc for tears or separation before each use and do not exceed the rated maximum speed. Eye protection and appropriate respiratory PPE should be worn during all abrasive operations per applicable safety standards.
