3M 7100145362 Sanding Disc 240 Grit 5 Inch Ceramic

Product Description

The 3M 7100145362 is a 5-inch hook-and-loop coated abrasive disc designed for fast stock removal on a wide range of substrates. It uses 3M Precision Shaped Grain technology, a ceramic mineral formed into a triangular shape that slices through material rather than plowing across it. The result is a disc that cuts significantly faster and outlasts conventional abrasive discs by a substantial margin. The film backing resists tearing and holds its edge longer than paper-backed alternatives. A precisely patterned multi-hole layout connects to dust extraction systems, keeping the work surface cleaner and extending disc life.

This disc is suited for professional finishing and stock removal applications in metal fabrication, automotive bodywork, woodworking, and composite surface preparation. The 240 grit rating positions it for intermediate to final surface prep where controlled material removal and a refined scratch pattern are required. The hook-and-loop attachment system speeds up disc changes on compatible random orbital and disc sanders, reducing downtime during production runs.

Key Features

• 3M Precision Shaped Ceramic Grain slices substrate for faster cut and longer disc life
• 240 grit rating for controlled stock removal and intermediate surface prep
• Film backing provides greater tear resistance and edge retention over paper backing
• Hook-and-loop attachment for fast, tool-free disc changes
• Multi-hole pattern supports dust extraction for cleaner sanding and extended disc life
• Suitable for metal, wood, composites, and other common substrates

Compatibility

Designed for use with 5-inch hook-and-loop random orbital and disc sanders that accept multi-hole film-backed abrasive discs.

Installation Notes

Mounting and removal require no tools — align the disc to the backing pad and press firmly to seat the hook-and-loop interface before use. Confirm the sander backing pad is clean and free of debris before attaching a new disc to ensure full contact and secure hold. Connect to a dust extraction system through the multi-hole pattern where available to maximize disc life and maintain visibility of the work surface. Inspect the disc before each use and discard immediately if tearing, delamination, or excessive loading is observed.
