I am attempting to use a spiral entry with a 3/16" cutter in a 3/8" hole geometry. But for some reason I'm getting these really huge toolpaths that go WAY outside the geometry. How do I remedy this? SEE PICTURE:

set number of steps (turns) to 5
set angle of approach to 5.5 or 6
see what happens

Thanks, I tested it and it looks better. I have no idea what that did but I think it worked.
thanks!!

this is pocket feature??
steps is how many times the tool will travel around
to reach the first level or bottom of hole
if this is a deep hole use step down!!!!
angle of approach is how steep the z is moving down
smaller angle will give you a larger circle
anytime the entry is out side the circle you are trying to cut
increase the angle of approach

hope you are using a upcut tool for this
test in scrap before putting to good wood easy to burn

hope this helps a little
