3M 7100145404 Sanding Disc 400 Grit 5 Inch Hook Loop

Product Description

The 3M 7100145404 is a coated abrasive sanding disc engineered for high-speed stock removal on a wide range of substrates. Built on a film backing for superior tear resistance and edge retention, this disc uses 3M Precision Shaped Ceramic Grain technology. The triangular ceramic mineral geometry is designed to slice cleanly through material rather than gouging or plowing, delivering cut rates up to 2x faster and service life up to 6x longer than conventional abrasive discs. At 5 inches in diameter with a 400-grit rating, it is suited for fine stock removal and surface refinement tasks. A hook and loop attachment system allows fast, tool-free disc changes during production work.

This disc is designed for use in professional finishing and fabrication environments where consistent cut rate and disc longevity directly affect productivity. The 400-grit rating makes it appropriate for intermediate to fine sanding stages on metal, wood, composites, and painted surfaces. A precision multi-hole pattern on the disc face supports dust extraction when used with compatible random orbital and disc sanders, keeping the work surface clear and extending abrasive life. It is commonly used by automotive body technicians, metal fabricators, woodworkers, and finishing professionals who require reliable performance across high-volume applications.

Key Features

• 3M Precision Shaped Ceramic Grain technology delivers cut rates up to 2x faster than conventional abrasives
• Abrasive life up to 6x longer than standard abrasive discs
• Film backing provides greater tear resistance and edge retention compared to paper-backed alternatives
• Hook and loop attachment system enables fast disc changes without tools
• Precision multi-hole pattern supports superior dust extraction during use
• Suitable for stock removal across metal, wood, composites, and painted substrates

Compatibility

Designed for use with 5-inch hook and loop random orbital and disc sanders equipped with compatible dust extraction ports. Confirm sanding pad hole pattern alignment before use for optimal dust extraction performance.

Installation Notes

A licensed or experienced finishing professional should verify that the sanding pad hole pattern matches the disc hole pattern before operation. Ensure the sander is powered off and unplugged before attaching or removing the disc. Press the disc firmly onto the hook and loop pad to ensure full engagement prior to use. Always wear appropriate eye and respiratory protection when operating abrasive discs.
