3M 7100027049 Hook Loop Disc 800 Grit 1 Inch Diamond

Product Description

The 3M 7100027049 is an 800-grit diamond abrasive hook and loop disc designed for precision surface finishing on hard, dense materials. Part of the 3M 6002J series, this disc features a coated diamond abrasive bonded to a flexible cloth backing, making it well suited for controlled material removal at super fine grade. At a grit micron rating of 20, it delivers consistent scratch patterns on surfaces that conventional aluminum oxide or silicon carbide abrasives struggle to finish cleanly. Weighing just 0.05 pounds, it is a single-use consumable sized at 1 inch in diameter. Installers and surface finishing technicians reach for this disc when tight geometry or hard substrate demands a diamond abrasive.

This disc is used in applications involving hard ceramics, carbide tooling, glass, stone, composites, and similarly dense substrates that require super fine surface refinement. The 1-inch diameter suits detail work, tight contours, and small-bore finishing tasks. The hook and loop attachment system allows fast disc changes on compatible random orbital or detail sanders without tools. No vacuum holes are present, so it is appropriate for dry finishing passes or use with equipment that does not rely on through-disc dust extraction.

Key Features

• 800 grit with 20-micron rating delivers super fine surface finish on hard materials
• Diamond abrasive construction handles ceramics, carbide, glass, and composites
• Flexible cloth backing conforms to contoured and irregular surfaces
• Hook and loop attachment enables fast, tool-free disc changes
• 1-inch diameter suited for detail, contour, and small-bore finishing work
• No vacuum holes — compatible with dry finishing or non-extraction tool setups

Compatibility

Designed for use with hook and loop random orbital and detail sanders accepting 1-inch diameter discs. Verify tool compatibility before use, as disc diameter and attachment style must match the backing pad.

Installation Notes

Attach the disc firmly to a clean, dry hook and loop backing pad before starting the tool. Inspect the backing pad regularly — a worn or contaminated pad reduces disc adhesion and can cause the disc to release during use. Allow the tool to reach operating speed before bringing the disc into contact with the workpiece. Disc is a consumable; discard when abrasive surface is worn or loading is visible.
