This CBN grinding wheel has been developed specially for the Tormek T-7 / T-8. The CBN-coated steel body is perfectly balanced and works without water or coolant, saving time and keeping your workplace dry. With only slight pressure, you achieve an excellent rate of stock removal and stunning grinding results. No risk of annealing for HSS and hardened steels. Sides not coated. The extreme hardness of the CBN abrasive grit ensures a long lifespan. Bore 32 mm. In combination with the adaptor flange No. 704888 it fits Tormek T-7 and T-8.
Grit:
Fine B54, stock removal similar to the performance of an aluminium oxide grinding wheel 250 grit, but with better surface finish.
Superfine B46, stock removal similar to the performance of an aluminium oxide grinding wheel 280 grit, but with better surface finish.
CBN-coating
CBN stands for Cubic Boron Nitride, an abrasive grain that is nearly as hard as diamond but much better suited for sharpening hardened steel. Sharpening on diamond wheels produces heat, and from around 170 °C causes a chemical reaction between the diamond grain and the steel alloys which destroys the diamond grain. CBN, on the other hand, only reacts at above 400 °C, and is only destroyed at 700 °C and above.
