3M 7010299233 Diamond Psa Disc 8 Inch Lapping

Product Description

The 3M 7010299233 is a Diamond Metal Bond PSA Disc designed for precision lapping, finishing, and polishing applications. Micron-graded diamond mineral is bonded to a brass plate using a metal bond matrix, producing consistent cutting action while delivering fine surface finishes. The pressure-sensitive adhesive backing allows fast, secure attachment to a machine platen or support plate without additional fasteners. At 8 inches in diameter, this disc suits bench lapping machines and surface finishing equipment commonly operated by machinists, toolroom technicians, and precision grinding specialists.

This disc is suited for lapping and finishing operations where controlled material removal and repeatable surface quality are required. It performs on a range of substrates including ceramic, carbide, and hard metals. Evenly-spaced diamond mineral distribution helps eliminate workpiece imperfections at a steady, controlled rate, making it a practical choice for flat lapping, fine finishing passes, and light polishing work in toolroom or production environments.

Key Features

• Micron-graded diamond mineral bonded to a brass plate for sharp cutting with fine finish results
• Pressure-sensitive adhesive backing for quick, secure mounting to a platen or support plate
• Evenly-spaced mineral layout promotes consistent, controlled material removal
• Suitable for use on ceramic, carbide, and other hard substrates
• Appropriate for lapping, finishing, and polishing applications

Compatibility

Designed for use with flat lapping machines and support plates that accept 8-inch PSA-backed abrasive discs.

Installation Notes

Installation is performed by trained machinists or abrasives technicians. Power down and lock out the lapping machine before removing a spent disc or mounting a new one. Clean the platen surface thoroughly before applying the PSA-backed disc to ensure full adhesive contact and prevent slippage during operation. Follow equipment manufacturer guidelines for platen speed and applied pressure appropriate to the substrate being lapped.
