3M 7100192077 Diamond Psa Cloth Disc 3 Inch 15000 Rpm

Product Description

The 3M 7100192077 is a diamond polishing PSA cloth disc designed for grinding and polishing hard-to-machine materials including carbides and ceramics. Micron-graded diamond particles are bonded to a flexible, J-weight waterproof cloth backing, producing a consistent cut with a long service life. The disc measures 3 inches in diameter with a 1/2 inch arbor and is rated for operation up to 15000 RPM. A pressure-sensitive adhesive backing allows fast, secure attachment to compatible disc holders without additional fasteners. This disc is suited for precision surface finishing applications where conventional abrasives lose effectiveness against hard substrates.

The 7100192077 is used in tool-and-die, machinist, and precision grinding applications involving carbide tooling, ceramic components, and other hard-to-grind materials. The waterproof cloth backing supports wet grinding with coolants, making it appropriate for applications where heat management and surface finish quality are both critical. The 3 inch diameter fits compact disc holders commonly used in bench and handheld precision finishing setups. Available grades in this disc family include 1800, 3000, 8000, and 50000 mesh, corresponding to 9, 6, 3, and 0.5 micron particle sizes, allowing users to select the correct grit for rough stock removal through final polishing.

Installation Notes

Installation is performed by machinists, tool-and-die technicians, or precision grinding specialists. Power down and lock out the grinding unit before mounting or removing the disc. Ensure the backing pad surface is clean and dry before pressing the PSA disc into place to achieve full adhesive contact. Do not exceed the rated 15000 RPM operating speed.
