Tool Library reduced shank

[SGoldthwaite]

I'm struggling with the shaft tab of the tool library for a reduced shank engraving bit.  I can't seem to figure out how to enter it so it matches the real thing.  My bit looks like this:

Shaft is 0.25", cutter is 0.375" diameter, 60 degrees

I would actually define it as a Spot Drill, which allows us to get something resembling what you actually have;

A spot drill can be used in a 2D Contour, Trace, Chamfer and the Engrave toolpath

That said; in this case, you don't "really" need to make a tool perfectly resemble the physical thing, as the shank isn't doing anything for you. I would just model it as a Chamfer tool with a .375 shank.

I know everything would work just fine without this shaft being accurate, but I wanted to figure out how to do it.  I find the shaft tab in the tool library can be hard to get right sometimes.

In this case, it doesn't seem that the Chamfer tool definition permits a square transition to the reduced shank, but rather, tapering back at the same angle as the tool tip
