TARO (JTB) Series

 

Recommended to customers who are reluctantly machining workpieces at low feed speed for fear of chipping damage.
The TARO (JTB) Series is available in four sizes that dramatically improve machining efficiency and indispensable to the rough machining of workpieces with a maximum Rockwell hardness of 48 HRC.
