Norton 3X Blue Grinding Wheel I Grade

Our Coolest Running Grinding Wheel

When speed is important to your grinding, the Norton 3X wheel is a wheel worth considering. Unlike other fast cutting wheels, the 3X wheel actually runs cool so you run less risk of overheating your tool. Our medium 60 grit is a good way to grind your initial bevel. After grinding, a few strokes on a bench stone and your tools are ready for use. This wheel is in a softer I-grade suitable for high carbon steel. Softer wheels run much cooler than harder wheels. The 8″ wheel has a 1″ arbor hole with bushings for 7/8″, 3/4″ and 5/8″ arbors and is rated for 3600 rpm. The 6″ wheels have a 1″ arbor hole with bushings for 7/8″, 3/4″, 5/8″ and 1/2″ arbors and are rated for 5410 rpm.
