Please note: If you do not have experience with the tools below used as a machinist, please do not apply. This is not a typical production machine operator position.

The tools that a machinist is expected to be proficient with fall into 6 broad categories:

  • Measuring tools:The measuring tools come in several basic varieties:
  • Comparison tools such as adjustableparallelsand plaincalipers,
  • Direct reading tools such as rules, scales, andvernier calipers,
  • Micrometertools based on screw threads,
  • Indicatortools based onclockworkgear movements,
  • Electronic measuring tools based ontransducers. Many of these are digital versions of their mechanical predecessors, as with a digitalcaliper.[3]
  • Hand tools:The hand tools are the usual complement of tools found in a complete auto mechanic’s set except that auto specialty tools would be absent and some outsized tools would likely be present, such as 1 1/2″ (38 mm) open end wrench.
  • Machine tools:The machine tools have undergone a dramatic shift in the last 20 years. Manual machines have given way to computer numerically controlled machines (CNCs). For clarity’s sake a categorization based on the historical groupings will be offered. Each of these groupings has been altered by the advent of CNCs and the CNCs meld some groups and blur the lines between others. In the past, the most common machine tools fall into 4 categories:
  • Drilling machines, bench, floor, radial, and horizontal
  • Milling machines, horizontal, vertical, and boring mills
  • Turning machines, engine lathe, turret lathe, vertical turret lathe, vertical boring mill
  • Grinding machines, surface, cylindrical, centerless, universal
  • Work holders:The work holders may includevises, chucks, indexing accessories, pallets, specialty jigs or fixtures, and faceplates
  • Tool holders:The tool holders may includechucks, cutter adapters, cutter extension, tool posts, indexable turrets, box tools, quick change adapters,arbors, andcollets.
  • Cutting tools:Cutting tools include various milling cutters such asface mills,shell mills,endmills, and form cutters; variousdrills,reamers,taps,countersinks,counterbores, andcore drills; variousturning tools, form tools, andthreadingtools; various grinding wheels[4]distinguished by their geometry, bond, grit size, and compound.
