Merit Abrasives 08834173052 Psa Disc 150 Grit 12in

Product Description

The MERIT ABRASIVES 08834173052 is a pressure-sensitive adhesive (PSA) abrasive disc designed for use on stationary disc sanders. It measures 12 inches in diameter and features 150-grit aluminum oxide abrasive on a flexible cloth backing. The PSA backing mounts directly to a compatible sanding platen without fasteners or hook-and-loop systems. At 150 grit, this disc falls in the very fine grade range, making it well suited for finish sanding, light material removal, and surface preparation on wood, metal, and composites. The flexible cloth backing conforms to the work surface and holds up under the heat and friction generated by stationary disc sanding applications.

This disc is intended for use on stationary disc sanders in shop and production environments. It is a standard consumable used by woodworkers, metal fabricators, and maintenance trades for surface finishing and prep work. The 12-inch diameter fits full-size stationary disc sander platens that accept PSA-mount media. No vacuum holes are included, which is consistent with solid-platen sanding setups where dust collection is handled separately.

Key Features

• 12-inch diameter fits full-size stationary disc sander platens
• 150-grit aluminum oxide abrasive for very fine finish sanding
• Pressure-sensitive adhesive backing for tool-free mounting and removal
• Flexible cloth backing conforms to the work surface and resists heat buildup
• No vacuum holes — compatible with solid-platen disc sander setups
• Black disc color for easy visual wear identification

Compatibility

Designed for stationary disc sanders that accept 12-inch PSA-mount abrasive discs with solid (non-vacuum) platens.

Installation Notes

Power down and disconnect the sander from its power source before changing discs. Clean the platen surface of any adhesive residue from the previous disc before applying the new PSA disc to ensure a flat, secure bond. Press the disc firmly from the center outward to eliminate air pockets. Allow the adhesive to seat for a moment before resuming operation.
