125mm diameter A6 grade 3M Trizact 237EA grip / velcro discs with a pop-out centre fit on the Cibo 125VEL/VZ back up pad which was designed specifically to ensure cool cutting and a long lifetime for the Trizact discs.
A6, 237GR Trizact finishing discs will quickly refine and blend the Trizact A16 grit sanding lines easier and more effectively than traditional abrasives to leave a P2000 grit finish.
The 2000 grit finish should have a bright and clear reflection but it is not technically mirror polished it is a mechanical bright finish.
Use the 115mm velcro discs as a fast and cost effective option for repairing bright polished stainless steel.. 237GR 125mm discs are particularly good for polishing thin wall stainless steel in preparation for mirror polishing.
Use the Trizact 237GR A6 discs after the A16 disc. Suggested polishing sequence:
1. Weld removal FX87GR P100 S133
