A) how deep (technically, wide) to make the cut?
B) Use a tool with a sharp tip, or small radiused tip (.005, .010, 1/64” etc)?
C) Make the cutter parallel to the base (perpendicular to the slide flat), or make the top & flat & cut symmetric by putting the cutter at an angle to bisect the intersection of the slide flat at top-tangent?
D) If parallel, cut it centered right ON the flat/round intersection line, or offset the cutter tip slightly below so the width of the cut comes up to the slide top intersection line?
E) why the hell are single-point threadmill cutters so expensive. And I don’t have an arbor saw for slitting either. Can I use a HSS double-angle cutter like this?
