One step finishing solution to reduce cost- Quiet, vibration-free grinding- Raised hub fits all standard grinder back flanges- Eco-Trim™ trimmable backing extends disc life by up to 3 times- Safe and easy to trim- With integral thread 5/8"-11 - Max RPM 13,300

A special top coat continuously cools and lubricates the disc for smooth, vibration-free grinding and sanding from start to finish. Moreover, there is no need to discard the disc when the flap overhang is worn down to the backing because the ENDURO-FLEX disc can be restored to like-new performance by reducing the diameter of the ECO-TRIM backing.
