New product: CBN Super High Precision Radius End Mill

SHPR400 Released in May, 2020.

CBN end mill, optimized for finishing on hardened steels.
Improve machining accuracy.
New tool design of 4 flute corner radius end mill.


Prevent wearing progress is important step to achieve stable machining accuracy when direct finishing on hardened steels. NS TOOL developed a new CBN end mill, which has higher wear resistance than coated carbide tool. The new corner radius type「SHPR400」reduces machining resistance and further improve machining accuracy and tool life. NS TOOL grinding technology developed 4-flute design from φ0.1mm and improved cutting quality with sufficient rigidity to realize a long time stable machining with higher efficiency and accuracy on finishing process.
