Axminster Workshop Aluminium Oxide Grinding Wheel 200mm x 40mm

White aluminium oxide grinding wheels have a slightly softer bond compared to standard grey grinding wheels. They are the ideal choice for sharpening tools as opposed to grinding. White wheels cut freely with far less tendency to overheat and draw the temper of the steel. This stone is 40mm wide, 80 grit for fast results and 200mm diameter with a 15.88mm (5/8") bore.
