Tyrolit CBN 14E1 wheel, 30° angle, is dedicated to finishing profiles on HSS tools, when surface quality and edge stability are decisive for life and accuracy. The 76 grit enables finer grinding than roughing, improving surface uniformity in contact areas and reducing friction and heat generation during real cutting.

Proper finishing helps limit adhesion and force variations that cause dimensional instability, especially when the chip must slide smoothly over clean, functional surfaces. In profiling, this means reducing the initiation of micro-defects and obtaining a more repeatable profile on the workpiece, with fewer corrections and better consistency over time. When to choose it: use it as the final pass on HSS after roughing, when you want to close the profile and improve the quality of the functional surface.
