Any one use carbide tools with their shaper? I've been playing around for awhile with different types of carbide and tool shapes for both finishing and rough cut tools. I'm getting a great finish with a carbide shear tool, better than with a corresponding HSS shear tool.
On a rough cut type tool I get a finish that would be every bit as good if not better than a corresponding tool in HSS (at the same depth,feed,speed).
I've used c2,c5 , K21 grades of carbide so far and haven't found a clear preference yet.
I'm using both a South Bend 7 and an Atlas 7, mostly with cr1018 steel. Carbide seems to need lots of cutting fluid for a good finish.
What have others learned about carbide? This seems like a little discussed topic for shapers.
