Mitutoyo 123-108 Series 123 Disk Micrometer, Hardened Steel Disks, 175-200 mm, 30 mm Disk Diameter

The Mitutoyo mechanical disk micrometer uses flat disks made with hardened steel in Mitutoyo Japanese facilities to measure lengths of spur and helical gears. The flatness and thinness of the disks allow for reliable measurements in tight spaces. A ratchet-stop mechanism provides uniform pressure on a workpiece for precise, repeatable measurements and eliminates over-speed error.

Features:

• Ratchet mechanism provides an audible click to ensure measurement is performed with constant force
• Knurled friction thimbles provide quick adjustments even when wearing gloves
• Satin chrome finish on the sleeve and laser etched measurements on thimble for easier reading
• Frame has a baked enamel finish for durability and longer lifespan
• Diameter of measuring disk: 30 mm.
• 1 mm edge thickness to enter narrow recesses.
• With ratchet stop for constant force.
• With a standard bar.
• Supplied in fitted wooden case.
