Finding a good
cutter to live tool internal threads can be a chore. I have never
been able to find a tool that would work "as-is". Every one has needed additional work to make
it usable.
Such is the nature of cuemaking.
I have a limited number of micro-grain carbide thread mills available
that are extra long and have relief ground far enough back to be used
not only for shaft threading - they are long enough for 3/8-10 FB joint
pin installation.
All grinding is perfectly concentric & tools will run as accurately
as
your collets will allow.
- IMPORTANT -
Please ensure that your spindle runs true.
A long-overhang cutter in a sloppy spindle is a recipe for disaster.
Excessive vibration can occur & it will be difficult to maintain
accuracy when cutting.
