Update:
I setup my machine to assert motion.feed-inhibit when the spindle falls
below the target RPM. This saved a tool immediately. Within minutes of
starting the test, there was a power surge that caused the spindle
controller to go off-line and the machine stopped feed, saving the tool.

Hello,
At least with my machine, holding the tap accurately is not an issue. It is
a CAT40 size spindle, and I use good quality collets that that have the
square hole at the bottom that the square end of the tap fits into. They
use in insert to compress around the shank that is like a really short

I clicked the link for ANSI sized, then found a part number, then
Googled that, and fo

My Tapmatic tapping heads seem to hold taps just fine. If I recall
correctly (I'll look in the shop later), they have two mechanisms:
1 -- A vise like mechanism that closes on the flat sides of the square --
that provides the driving power
2 -- A rubber flex collet -- that provides the alignment

Hello everyone,
Thank you very much for your comments and suggestions. To me the tap is not
the issue, a broken tap in a hole IS an issue, so it is all about not
breaking the tap if the spindle faults out. As long as the axis stays
slaved to the spindle, the tap can be removed by hand. There is not

Does motion.feed-inhibit sound like what you need?
