3M 7100053375 Hook Loop Disc 400 Grit 1.5 in Diamond

Product Description

The 3M 7100053375 is a hook and loop abrasive disc engineered for precision surface finishing on hard materials. Built around a diamond abrasive matrix with a cloth backing, it delivers consistent material removal at a super fine 400 grit rating, corresponding to a 40-micron grit size. The disc measures 1.5 inches in diameter and mounts quickly via a hook and loop interface, making pad changes fast during repetitive finishing work. Its flexible construction conforms to slightly curved or contoured surfaces without losing cutting efficiency. This disc is suited to trade professionals and skilled tradespeople performing detail grinding, honing, or finishing work where tight tolerances and a refined surface finish are required.

This disc is designed for use on hard, dense materials such as ceramics, glass, stone, carbide, and composite surfaces where conventional aluminum oxide or silicon carbide abrasives lose performance. At 1.5 inches, it fits compact orbital or right-angle tools used in tight-access finishing applications. The super fine 400 grit designation makes it appropriate for final-stage stock removal or intermediate finishing before polishing. The yellow cloth backing provides dimensional stability and resistance to tearing under moderate pressure.

Key Features

• Diamond abrasive material for high-durability cutting on hard substrates
• 400 grit super fine grade for refined surface finish and controlled stock removal
• 1.5-inch diameter fits compact hook and loop backing pads
• Flexible cloth backing conforms to slightly contoured work surfaces
• Hook and loop attachment system allows fast disc changes without tools
• No vacuum holes — designed for dry or manual finishing applications

Compatibility

Designed for use with 1.5-inch hook and loop backing pads on compact orbital, die grinder, or right-angle finishing tools. Part of the 3M 6002J series.

Installation Notes

This disc is installed by pressing the loop side firmly onto a compatible hook-face backing pad — no tools required. Ensure the backing pad is clean and free of debris before mounting to maintain full contact and prevent premature disc separation. Disconnect or power down the tool before changing discs. Follow applicable workplace safety standards for abrasive tool RPM ratings and use appropriate eye and respiratory protection when grinding hard materials.
