Merit Abrasives 08834172115 Psa Disc 9 in 24 Grit

Product Description

The MERIT ABRASIVES 08834172115 is a 9-inch PSA (pressure-sensitive adhesive) abrasive disc designed for aggressive material removal on flat surfaces. It uses aluminum oxide grain at 24 grit, placing it in the very coarse grade range — suited for rapid stock removal, weld grinding, heavy surface shaping, and coating stripping. The cloth backing provides durability and flexibility, allowing the disc to conform slightly under load without tearing. This disc weighs approximately 0.5 pounds per unit. It is a single-disc package and is installed directly onto a compatible PSA disc pad or backing plate.

This disc is used in metal fabrication shops, woodworking operations, and general industrial grinding applications where fast, aggressive cutting is the priority. Very coarse 24-grit aluminum oxide is appropriate for initial grinding passes, removing rust or mill scale, shaping raw stock, or preparing surfaces before finer-grit finishing steps. The flexible cloth backing makes it suitable for use on angle grinders and disc sanders where some substrate compliance is needed. The disc does not include vacuum holes, so it is intended for use with non-perforated backing pads.

Key Features

• 9-inch diameter PSA disc with pressure-sensitive adhesive backing for quick mounting and removal
• 24 grit aluminum oxide abrasive — very coarse grade for maximum stock removal rate
• Flexible cloth backing withstands grinding pressure and resists tearing during heavy use
• No vacuum holes — compatible with solid, non-perforated PSA backing pads
• Black disc color; sold as a single-disc unit

Compatibility

Designed for use with 9-inch PSA backing pads and disc sanders or angle grinder assemblies that accept pressure-sensitive adhesive discs without vacuum holes.

Installation Notes

Installation is performed by trade and industrial users familiar with abrasive disc equipment. Power down and fully de-energize the grinder or disc sander before mounting or removing the disc. Peel the release liner from the PSA backing and press the disc firmly and evenly onto a clean, dry backing pad to ensure full adhesion before operation. Inspect the disc for damage before each use and do not operate at speeds exceeding the rated RPM of the backing pad or tool.
