237GR Trizact A30 grade grip disc 50mm dia

50mm diameter A30 grade 3M Trizact 237EA grip /velcro discs fit on the Cibo 50vel back up pad which was designed specifically to ensure cool cutting and a long lifetime for the Trizact discs.

A30 237GR Trizact finishing discs will quickly refine and blend the Trizact A65 grit sanding lines easier and more effectively than traditional abrasives without the risk of undercuttting to leave a P800 grit finish.

Use the 50mm 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 polishing thin wall stainless steel in preparation for mirror polishing.

Although Trizact works best at slower operating speeds, 50mm A30 discs can work effectively on 115mm or 125mm angle grinders when used with a 50mm velcro back up pad.

Use the Trizact 237GR A30 discs after the A160 disc. Suggested polishing sequence:
