OSG Diameter correction tool for thread mill with memory for DCT 6H

By using the diameter correction tool for thread mills, you can easily quantify the effective diameter of the thread opening, which has previously been difficult to measure.
If the effective diameter of the stop gauge is negative, you won't know how much to change the tool radius offset value for thread milling.
However, if you have a diameter correction tool for thread mills, you can also measure the minus effective diameter. Appropriate corrections can be made without worrying about enlargement. Helps significantly reduce setup time.
By quantifying the effective diameter of the female thread opening, it is possible to make the effective diameter of the female thread almost the same after tool replacement.
By making the start position the same, the goal position (tool life) can also be made the same, which stabilizes the tool life.
Can also be used for 5H, class 2, and class 1 female threads. The measurement range is female thread (6H) tolerance 100% to -50%.
When the diameter correction tool is screwed in and the sleeve stops, the effective diameter of the mouth can be quantified using the line and scale on the sleeve. (Used for diameter correction during thread mill processing setup)
*If the female thread is a blind hole, please confirm that the female thread length is longer than the DCT thread length.
