I never have ground the top of a parting tool -- but then I've never
had problems with them either. I'll try a little grinding before I
pitch it and pick up a new one.

Karl sure likes his carbide tool. Maybe I'll try one of those.

You usually don't want to grind the top especially if this is the long
blade type. Grind the front face back. Also, a machinest aquaintance
told me to experiment with the angle of the front face (i.e. front
clearance). There is an optimum for best cutting versus chatter. I
found this to be true.
