3M 7010307650 Diamond Psa Cloth Disc 6 Inch Abrasive

Product Description

The 3M 7010307650 is a diamond polishing PSA cloth disc designed for grinding and polishing hard-to-grind materials including carbides and ceramics. The disc uses micron-graded diamond particles bonded to a flexible, J-weight waterproof cloth backing, delivering consistent cut and long service life in demanding finishing applications. A pressure-sensitive adhesive (PSA) backing allows fast, tool-free mounting to compatible backup pads. At 6 inches in diameter and weighing 0.1 pounds, this disc is suited for precision surface finishing where conventional abrasives fall short. It is sold individually and compatible with wet or dry use.

This disc is used in precision grinding and polishing operations on carbide tooling, ceramic components, and other superhard workpieces. It is a practical choice for tool and die shops, production grinding cells, and lapping operations where tight surface-finish tolerances are required. The waterproof cloth backing allows use with water-based and oil-based coolants, making it well suited for wet grinding setups. Available grades span from coarse stock removal to ultra-fine polishing, covering a wide range of finishing stages.

Key Features

• Micron-graded diamond mineral for consistent performance on carbides, ceramics, and other superhard materials
• Flexible J-weight cloth backing conforms to workpiece surfaces and resists tearing
• Waterproof construction supports use with water-based and oil-based coolants
• Pressure-sensitive adhesive backing allows quick mounting and removal with no tools
• Available in mesh grades 1800, 3000, 8000, and 50,000 (corresponding to 9, 6, 3, and 0.5 micron)
• Long service life reduces disc change frequency in production environments

Compatibility

Designed for use with 6-inch PSA backup pads on bench grinders, lapping machines, and rotary finishing equipment used in precision tooling and ceramic finishing applications.

Installation Notes

Installation is performed by pressing the PSA-backed disc firmly onto a clean, dry, compatible 6-inch backup pad — ensure the pad surface is free of debris or residue before mounting. Power down the machine completely before changing discs. Inspect the disc for damage before each use and do not exceed the speed rating of the backup pad in use. Wet grinding with coolant is supported, but ensure the machine and workholding setup are rated for wet operation.
