Mitutoyo, 293-668-20, 293 Series Digital Absolute Micrometer QuickMike, 50-80mm
Features:
- Non-rotating spindle and the ratchet friction thimble reduces torsion on softer parts being measured
- Ratchet thimble allows for easy single-hand use when measuring objects
- ABSOLUTE linear scale eliminates the need for setting the origin point every time the micrometer is powered on
- Elimination of overspeed errors provides a higher measurement reliability and repeatability
- IP54 protection permits use in environments exposed to cutting oil, coolant, dust, etc., for use on most shop floor environments
- Includes a standard bar to set the origin point (for models with 25-55mm / 1-2.2″ ranges or larger)
- Supplied in fitted plastic case
The Mitutoyo Digimatic Quickmike coolant proof digital micrometer feeds the spindle 10mm per thimble rotation, or 20-times faster than standard micrometers. This speed provides quicker measurements on different sized features. Its wide 30mm / 1.2″ measuring range allows for measuring of different workpieces without sacrificing speed or accuracy.
