This Digimatic Spline Micrometer makes it easy for you to measure grooves and shaped parts. It offers you the following benefits:

  • Outstanding accuracy and oil-resistant material used for all plastic parts (IP65).
  • Anvil and spindle are of small diameter for measuring splined shafts, slots and keyways.
  • Excellent resistance against water and dust (IP65 protection level) enables this micrometer to be used in machining situations that include splashing coolant fluid.
