3M 7100045072 Sanding Disc 80 Grit 6 Inch Ceramic

Product Description

The 3M 7100045072 is a coated abrasive sanding disc engineered for high-performance stock removal in professional finishing and surface preparation applications. It uses 3M Precision Shaped Grain technology, where triangular ceramic mineral particles are designed to slice through material rather than gouge or plow like conventional abrasives. The result is a disc that cuts up to 2 times faster and lasts up to 6 times longer than standard abrasive discs. The film backing adds tear resistance and helps maintain edge integrity during aggressive sanding passes. A hook and loop attachment system allows for quick disc swaps without tools.

This disc is suited for professional surface prep work across a wide range of substrates, with the primary focus on stock removal. The 6-inch diameter and 80 grit rating make it appropriate for initial material removal before progressing to finer grits. A multi-hole pattern integrated into the disc face supports dust extraction systems, keeping the work surface cleaner and improving visibility during use. It is commonly used in automotive body, woodworking, and general fabrication environments by tradespeople who require consistent, repeatable cut rates over extended use cycles.

Key Features

• 3M Precision Shaped Grain ceramic mineral slices material for faster, cleaner stock removal
• Cuts up to 2 times faster than conventional abrasive discsService life up to 6 times longer than conventional abrasives
• Film backing provides greater tear resistance and edge retention
• Hook and loop attachment system enables fast, tool-free disc changes
• Precise multi-hole pattern supports dust extraction for cleaner work surfaces

Compatibility

Designed as an OEM-style replacement or direct-use disc for 6-inch hook and loop random orbital and disc sanders in professional finishing and fabrication settings.

Installation Notes

Installation requires a 6-inch hook and loop backing pad on a compatible random orbital or disc sander. Ensure the sander is powered off and unplugged before attaching or removing discs. Align the disc holes with the sander pad holes to maintain dust extraction performance. Inspect the backing pad regularly for wear, as a degraded pad reduces disc adhesion and can cause disc detachment during use.
