IT TOOLING SYSTEM
What is IT Shank Tooling?
IT shank is based on ISO 7388/1-'83 (DIN69871-'90) and its flange has an unsymmetrical shape. -Depth of Drive Key Slots are different. -V Notch on one side. Therefore, NIKKEN IT_X shank has a groove at bottom of V groove for mass balancing. Diameter “D” below the flange is restricted under the above standard. Normally the holder for large diameter cutter has a large body, therefore, large diameter at “D” is expected. However, in case of IT Shank large diame- ter tool holder, “D” is smaller than the front end part due to the standard, and the length from gauge line is also different from BT Shank tool holders.

IT-X has to be balanced by machining this area due to the unsymmetrical design of IT (Drive Key Slot and V Notch).
