All 3M belts feature exceptionally durable cloth backings and smooth, strong splices to reduce chatter. The backings, adhesives and abrasive minerals used on each belt are all carefully matched to make sure they work together. This innovative construction helps the cutting surface stay cool, which minimizes loading and maximizes belt life. 3M Brand belts are economical and use a high-quality synthetic mineral. 3M Sine-Lok Splice, with its innovative, low-profile angle, reduces chatter, resulting in a smoother, flatter, more professional finish.
Purple 3M Regalite Belts feature our patented 3M Cubitron ceramic aluminum oxide mineral that starts sharp and stays sharp long after many other belts have stopped cutting.
Black 3M Tri-M-ite Belts are recommended for removing hard, old finishes, such as shellacs, varnishes and paints.
