Tyrolit CBN 14E1 wheel, 30° angle, in 200 mm diameter, is optimized for finishing the profile on HSS tools when you need to maximize surface quality and cutting edge stability in operation. The 76 grit helps reduce micro-irregularities that increase friction and temperature and can destabilize chip formation and evacuation, especially in repetitive operations where dimensional consistency is critical.

In profiling, this wheel “qualifies” the final profile: it improves surface regularity in functional zones and helps make forces and wear more predictable, increasing tool life and reducing dimensional drift. Used as the final pass after roughing, it allows you to close the profile with higher accuracy and achieve more stable behavior over time. When to choose it: use it for finishing on HSS after roughing, when you want better surface quality, less heat and higher profile repeatability.
