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.
