  • All figures are for the United States as a whole. Pay varies a lot by state and city.
  • Wages are for everyone working in the occupation in May 2025, at every career stage. They are not starting salaries or figures for new graduates.
  • Growth and openings are BLS projections for 2025–35. They are estimates, not promises. Openings include jobs that open up when people retire or change occupation, not just new jobs.

What the work involves

Set up, operate, or tend drilling machines to drill, bore, ream, mill, or countersink metal or plastic work pieces.

Main tasks

  • Verify conformance of machined work to specifications, using measuring instruments, such as calipers, micrometers, or fixed or telescoping gauges.
  • Study machining instructions, job orders, or blueprints to determine dimensional or finish specifications, sequences of operations, setups, or tooling requirements.
  • Move machine controls to lower tools to workpieces and to engage automatic feeds.
  • Verify that workpiece reference lines are parallel to the axis of table rotation, using dial indicators mounted in spindles.
  • Establish zero reference points on workpieces, such as at the intersections of two edges or over hole locations.
  • Change worn cutting tools, using wrenches.
  • Select and set cutting speeds, feed rates, depths of cuts, and cutting tools, according to machining instructions or knowledge of metal properties.
  • Position and secure workpieces on tables, using bolts, jigs, clamps, shims, or other holding devices.
