Advantages of Cotton-Fiber Abrasives


Reduced grinding time. Our abrasives consistently reduce finishing from two or three steps, to just one.

Non-loading. Cotton Fiber abrasives are naturally non-loading so they will not clog when working on aluminum.

Cool action. Due to the cotton fiber construction, new grain is continually exposed during the grinding process resulting in a cooler operation.

Smooth, Quiet Action. Our cotton fiber abrasive material is resilient, which creates very low vibration products. Rex-Cut products run chatter free and are easy on the operator.

Application tailored. Many grit, bond, and size options are available to suit specific applications.
