Apparently my description has not been adequate to describe what I want,
which is keying the tap holder slug into the R8 so that it cannot rotate
within the keyless bore of an R8 tool holder. The half circle, or a
little over a half circle, as pointed out in the attached scribble, is
where I want to cut away so as to allow the head of a 4mm socket head
screw to enter into the cutaway shown in the end of the R8 so as to key
the "tap hat" slug to the R8, already keyed to the spindle by its pin
and locking slot, removing yet another potential point of slippage to
screw up a hole while rigid tapping it.
Short of spending 6 months to learn how to run one of the cadcam gfx
engines and make a professional drawing, its the best I can do on the
back of an envelope. My water bill TBE. :)
