Cutting & drilling 110 copper, good carbide cutters .375 & .5. 2-flutes, No cadcam here programing manual on a brand new HAAS VF2SS from old school paper draftsmen prints. I need help with the feed & speed (IPM & RPM) looking for good tool life as opposed to maxing it out. Main issue is drilling.....getting chips wrapped around drill using carbide TSC drills. Thanks
