1 Inch 800 Grit (A10-Blue) Dual Lock Backed 3M 268XA Trizact Disk Pack of 3

3M's 268XA Trizact material is an embedded aluminum oxide structure with small pyramid shapes on the surface of this disk that allows for quick, high removal of material, but with a super fine finish of aluminum oxide on the glass surface. The Trizact disks are an excellent choice for pre-polish finishing of your glass surfaces before moving to a final polish with cerium oxide.

The softer aluminum oxide abrasive is perfect for cleanup on surfaces to give a semi-transparent finish on the glass that is super easy to polish.

Be aware that Trizact disks will generate a lot of surface heat while working your glass,so be careful not to overdo it or you'll end up with micro-fractures in your glass surfaces.
