3M™ Trizact™ Cloth Belt 237AA uses proprietary microreplication technology where micron-graded aluminum oxide particles are formed into tiny pyramids of abrasive mineral and then coated on an X weight cloth backing. As these pyramids wear, fresh, sharp mineral is continually exposed to produce a consistent cut and a predictable, fine finish.

The abrasive and resin structure for the 3M™ Trizact™ Cloth Belt 237AA is formulated to break down under medium pressure and keep fresh, sharp mineral cutting to provide consistent finishes on hard metals such as carbon and stainless steel. These belts also features a grinding aid that helps prevent heat buildup, warping and discoloration. The belt is constructed on an X-weight, durable cloth backing that helps provide control, conformability, and effective medium-pressure grinding. The resin bonded abrasive gives you greater heat resistance and helps prevent delamination.

We recommend using Trizact belts for fine finishing of all steels. They are especially good for finishing blades on our Plunge Platens
