Description

CBN HONING

The entire outer surface of this honing plate is coated with fine CBN grain. The plate is not only suitable for sharpening the inside of turning tools but its large even surface also allows universal use. The HonStar is inherently stable, unbreakable and has an extremely long life. Radiuses 2.7 and 6 mm.

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.
