Merit Abrasives 08834172016 Psa Disc 5 in 36 Grit

Product Description

The MERIT ABRASIVES 08834172016 is a pressure-sensitive adhesive (PSA) abrasive disc designed for aggressive material removal on flat and contoured surfaces. Built on a flexible cloth backing, this disc conforms to workpiece geometry and holds up under the heat and friction of heavy grinding and shaping operations. The abrasive material is aluminum oxide at 36 grit, placing it in the very coarse grade range — best suited for rapid stock removal, weld blending, and surface preparation prior to finer finishing passes. The disc measures 5 inches in diameter and mounts directly to PSA-compatible random orbit or disc sanders without fasteners or clips.

This disc is used in metalworking, fabrication, woodworking, and general surface preparation applications. The 36-grit very coarse cut makes it a first-stage tool where significant material needs to be removed quickly. It is commonly used on steel, aluminum, wood, and composite surfaces in shop or field settings. Fabricators, welders, millwrights, and finish carpenters reach for this grit level when leveling welds, removing rust, shaping edges, or flattening rough stock. No vacuum holes are included, making it suited for sanders without dust-extraction ports.

Key Features

• 5-inch diameter fits standard PSA disc sanders and random orbital tools with PSA platens
• 36-grit aluminum oxide abrasive for fast, aggressive stock removal
• Very coarse grade — effective on metal, wood, and composite surfaces
• Flexible cloth backing conforms to surface contours and resists tearing
• Pressure-sensitive adhesive backing for tool-free mounting and removal
• No vacuum holes — compatible with solid-platen PSA sanders

Compatibility

Designed for use with 5-inch PSA (pressure-sensitive adhesive) platen sanders and disc grinders that accept self-adhesive abrasive discs without hook-and-loop or mechanical fastening systems.

Installation Notes

Ensure the sander platen is clean and free of adhesive residue before applying the disc; contaminants reduce bond strength and can cause the disc to separate during use. Peel the backing liner and press the disc firmly onto the platen from the center outward to eliminate air pockets. Always confirm the tool is powered off and unplugged before changing discs. Wear appropriate eye protection and gloves when handling abrasive discs and operating grinding equipment.
