＊ mark : The tolerances of the extension of the spindle flange from gauge face depend on the M/C. Please be careful to check your M/C specification especially for ATC arm and magazine, when NIT tooling is going to use on the M/C with IT standard spindle. Because, the flange thickness of NIT tooling is 1.7mm （ NIT50 ） or 2.2mm （ NIT40 ） larger than the thickness of the IT standard tooling.
