The Diameter Correction Tool (DCT) for thread mills makes it easy to quantify values of the internal thread effective diameter, which used to be difficult to measure. The DCT enables quick and simple measurement with readable values; while the DCT75 (optional accessory) is able to measure, calculate and digitally display results. Select the perfect combination based your specific application needs.
Achieves Stable Tool Life with Accurate Diameter Measurement
How can we properly determine the diameter correction value?
When the effective diameter of the limit gauge is minus, the radius correction value of the thread mill cannot be determined. However, with the use of the thread mill Diameter Correction Tool (DCT), the effective diameter can be measured with readable values. Proper diameter correction value can eliminate the risk of hole expansion, allow appropriate adjustment and significantly reduce setup time.
Will the internal thread effective diameter be the same after changing tool?
Knowing the internal thread effective diameter value can help maintain the same effective diameter after exchanging tool. As long as the starting position is the same, it can be aligned to help predict and stabilize tool life.
Features
