75mm diameter A65 grade 3M Trizact 237EA grip / velcro discs fit on the Cibo 75VEL/VZ back up pad which was designed specifically to ensure cool cutting and a long lifetime for the Trizact discs.
A65 237GR Trizact finishing discs will quickly refine and blend the Trizact A160 or P150 grit sanding lines easier and more effectively than traditional abrasives without the risk of undercuttting to leave a P280 grit finish.
Use the 75mm velcro discs as a faster and more cost effective option than the traditional roloc type quick change pads. 237GR 75mm discs are particularly good for sanding fine limit sheet metal with thin wall stainless steel tig weld removal.
Although Trizact works best at slower operating speeds, 75mm A65 discs can work effectively on 115mm or 125mm angle grinders when used with the75VEL/VZ back up pad + 75IT foam interface layer.
