What is the guideline for A-SFT and A-POT material hardness?
The approximate material hardness (HRC) that can be processed by A-SFT AND A-POT is as follows.
A-SFT：30HRC
If the hardness exceeds the above, it is necessary to select a Tap of a different series.
spiral fluted tap }}
～42HRC VP-SFT
spiral pointed tap }}
～45HRC CPM-POT
If you have equipment with a helical complement function (3-axis simultaneous control), we recommend the AT-2 thread mill for high-hardness steel.
It is possible to handle material hardness up to ~60HRC. AT-2
