Well that hundred dollar bit did it's job.
I hated spending that much for it but what I hate more is not doing something right.
Even though a chip out could probably be covered by the tuner, I still know if it's there
and that just doesn't work for me.

The cool thing is that there are two
different sized areas for the machine to fit in and this bit cuts them both at the same time.

This has been a part of builds that needed to be fine tuned and I sure feel good about the results. Beautiful holes with no chip out.

Trial fit and no issues.

Alignment has to be. Not a very good photo but alignment is right on.
Da-Vinci tuners...love the look and quality.
One more milestone reached.
