GRINDING DISCS/WHEELS:
While flap discs might be the popular option in the abrasives category, grinding discs or grinding wheels are the preferred choice when heavy material removal is required. Our grinding discs are engineered for aggressive stock removal and extra-long life.

We offer grinding discs in various sizes including 4.5”, 5”, 6”, 7” and 9”.
