3M 337DC Gator Trizact Abrasive Belts – Structured Finishing Belts for Consistent Results

The 3M 337DC Gator Trizact abrasive belt is designed for finishing processes where you need repeatable, consistent surface quality. Trizact belts use micro-replicated structured abrasive technology, producing a predictable scratch pattern and controlled wear compared with conventional coated abrasives.

337DC is often used for scratch refinement and finishing steps where appearance and uniformity matter — helping reduce rework and variation between belts and operators.

Trizact vs Compact Grain vs Standard Coated
