3M 7000118115 Abrasive Disc Roll 5 Inch P320 Grit

Product Description

The 3M 7000118115 is a coated abrasive disc roll in the Stikita 210U series, designed for lightweight sanding and finishing applications. Each roll contains 5-inch diameter discs with P320 grit aluminum oxide abrasive on an A-weight paper backing. The open-coat construction reduces loading by minimizing dust buildup on the abrasive surface and the workpiece. The Stikita pressure-sensitive adhesive backing allows fast, secure attachment to compatible backup pads without disc liners, keeping workflow moving on the shop floor or job site.

This disc roll is suited for finishing passes on wood, composites, painted surfaces, and light metals where a fine P320 grit is appropriate. The roll format eliminates the need to handle individual disc liners, making it practical for production environments, cabinet shops, and finish carpentry operations. The A-weight paper backing conforms well to contoured surfaces, making it a workable choice for detail sanding and surface prep before coating or staining.

Key Features

• Aluminum oxide abrasive offers durable, fast-cutting performance across a range of surfaces
• P320 grit is well-suited for fine sanding, finishing, and pre-finish surface preparation
• Open-coat construction reduces abrasive loading and extends disc life
• A-weight paper backing provides flexibility for lightweight sanding and contour work
• Stikita adhesive backing enables quick attachment and removal with no liner to discard
• Roll format increases productivity by dispensing discs cleanly and consistently

Compatibility

Designed for use with 5-inch backup pads that accept pressure-sensitive adhesive (PSA) disc attachment. Verify that the backup pad surface is clean and free of debris before applying each disc to ensure proper adhesion.

Installation Notes

These discs are installed by hand onto a PSA-compatible 5-inch backup pad mounted to a random orbital or disc sander. Power down the tool completely before changing discs. Press the disc firmly and evenly onto the pad surface to ensure full adhesive contact. Remove worn discs promptly, as a disc that lifts at the edges during use can cause uneven finish or workpiece damage.
