Merit Abrasives 05539562621 Hook Loop Disc 2 in 50 Grit

Product Description

The MERIT ABRASIVES 05539562621 is a 2-inch hook-and-loop abrasive disc designed for surface preparation, blending, and finishing work. The disc uses a non-woven aluminum oxide construction rated at 50 grit, placing it in the coarse grade range. The hook-and-loop backing allows fast disc changes on compatible random orbital and right-angle sanders without tools. With a maximum rated speed of 30,000 RPM, this disc handles demanding stock removal tasks on metal, wood, and composite surfaces. It is sold individually and requires a minimum order quantity of 50 units, making it suited for shop stocking or fleet maintenance programs.

This disc is used in light fabrication, metal finishing, weld blending, and surface conditioning applications. The non-woven aluminum oxide construction delivers consistent cut rate and surface finish without loading as quickly as coated abrasives under similar conditions. The flexible construction conforms to slightly contoured surfaces, reducing the need for hand finishing in follow-up steps. Typical users include metal fabricators, maintenance technicians, and finishing trades professionals who cycle through abrasive consumables at volume.

Key Features

• 2-inch disc diameter for use with small random orbital and detail sanders
• 50 grit coarse grade aluminum oxide for aggressive stock removal and weld blending
• Non-woven construction resists loading and conforms to mild contours
• Hook-and-loop backing enables tool-free disc changes
• Rated to 30,000 RPM for compatibility with high-speed pneumatic and electric tools
• No vacuum holes, keeping cost low for solid-pad sander configurations

Compatibility

Designed for use with 2-inch hook-and-loop backup pads on pneumatic and electric random orbital sanders and right-angle grinders configured for small-diameter abrasive discs.

Installation Notes

Mounting and removal require no tools — press the disc firmly onto a clean, dry hook-and-loop backup pad before use. Verify the backup pad and tool spindle are rated at or above 30,000 RPM before operation. Inspect the disc for tears or delamination before each use and replace immediately if damage is found. Wear appropriate eye protection and respiratory protection when operating abrasive discs per applicable OSHA and shop safety standards.
