3M 7100145452 Sanding Disc 400 Grit 3 Inch Hook Loop

Product Description

The 3M 7100145452 is a 3-inch hook-and-loop sanding disc designed for high-efficiency stock removal across a wide range of substrates. Built on a film backing with Precision Shaped Ceramic Grain technology, the triangular ceramic mineral is engineered to slice through material rather than gouge or plow like conventional abrasives. At 400 grit, this disc is suited to fine stock removal and surface finishing tasks. The film backing provides tear resistance and edge retention, while the precise multi-hole pattern enables superior dust extraction during use. Licensed trades and finishing professionals working on metal, composite, or painted surfaces will find this disc well-suited to production-rate applications.

This disc is designed for use in automotive refinishing, metalworking, woodworking, and general surface preparation. The hook-and-loop attachment system allows for fast disc changes without tools, reducing downtime on the work surface. The 3-inch diameter fits standard random orbital and disc sanders equipped with a compatible hook-and-loop pad. The 400 grit rating makes it appropriate for intermediate to final-stage sanding where controlled material removal and surface consistency are required.

Key Features

• Precision Shaped Ceramic Grain technology cuts up to 2x faster than conventional abrasives
• Ceramic mineral geometry slices substrate cleanly rather than gouging, extending disc life up to 6x versus conventional abrasives
• Film backing delivers greater tear resistance and edge retention compared to paper-backed alternatives
• Multi-hole pattern engineered for superior dust extraction, reducing loading and improving visibility
• Hook-and-loop attachment enables fast, tool-free disc changes
• Suited for stock removal on metal, composite, wood, and painted surfaces

Compatibility

Designed for use with 3-inch random orbital and disc sanders equipped with a hook-and-loop backing pad. No specific compatible model numbers were provided in the product data.

Installation Notes

Installation is performed by pressing the disc firmly onto a compatible hook-and-loop sanding pad until fully seated. Confirm the sander pad diameter matches the disc diameter before use. Do not exceed the rated maximum speed of 15000 RPM. Always wear appropriate eye and respiratory protection when sanding, and ensure adequate ventilation or dust collection is in place before operating.
