Merit Abrasives 08834172018 Psa Disc 5 in 50 Grit Aluminum Oxide

Product Description

The MERIT ABRASIVES 08834172018 is a 5-inch pressure-sensitive adhesive (PSA) sanding disc designed for material removal and surface preparation in production and finishing environments. Built with aluminum oxide abrasive on a flexible cloth backing, this disc delivers consistent cut at a coarse 50 grit rating. The PSA backing allows for fast, tool-free mounting to compatible backup pads. At 0.01 pounds per disc, it is a lightweight consumable suited for high-volume use. The flexible cloth construction conforms to slightly irregular surfaces, making it practical for both flat and contoured workpieces.

This disc is used in grinding, deburring, and aggressive stock-removal operations across metalworking, fabrication, and woodworking applications. The coarse 50 grit designation makes it appropriate for initial surface preparation, weld blending, and rust or scale removal. It is typically used by machinists, fabricators, and finishing technicians operating 5-inch PSA-style orbital or disc sanders. The black disc color and flexible backing are consistent with heavy-duty service conditions. No vacuum holes are included, making this disc suited for solid backup pads without dust-extraction ports.

Installation Notes

Mounting is performed by peeling the liner from the PSA backing and pressing the disc firmly onto a clean, dry backup pad. Ensure the sander is powered off and disconnected before changing discs. Inspect the backup pad for damage or debris before mounting each new disc. Follow applicable ANSI and OSHA guidelines for abrasive wheel and disc use, including appropriate RPM ratings and personal protective equipment.
