ChipDial

ChipDial is a focused machining calculator for machinists, CNC operators, and small shops. Calculate spindle RPM, surface speed, speeds and feeds, turning feed, drill feed, tap drills, thread pitch, taper angles, chamfers, bolt-circle coordinates, and shop geometry. Use Imperial or Metric units, save recent calculations locally, and restore favorite setups when needed. ChipDial works offline and does not require an account, subscription, advertising, or network connection. These calculations are starting points for process planning. Always verify tooling data, workholding, machine limits, material condition, and safe operating procedures before cutting.
