Mitutoyo 505-746 Dial Caliper 0 - 12", Graduation .001", .1"/rev
Part No. 505-746 | Range 0–12" | Graduation 0.001" | Accuracy ±0.002"
Product Overview
The Mitutoyo 505-746 is a Series 505 mechanical dial caliper with a 0–12" measuring range, 0.001" graduation and ±0.002" specified accuracy. It measures outside dimensions, inside dimensions, depths and steps with one instrument, making it suitable for general dimensional inspection and workshop measurement.
The mechanical analog dial provides direct readings without batteries. The Series 505 dial movement is designed for smooth slider operation and high shock protection, supporting regular use in machining, fabrication, maintenance and inspection environments.
This model uses standard hardened stainless steel jaws for general-purpose measurement across a wide range of workpieces. One revolution of the dial represents 0.1", with each dial graduation corresponding to 0.001". This configuration provides finer jaw travel per revolution than the 505-749, which is listed with 0.2" per revolution.
The extended 12" measuring range is useful for larger components such as housings, flanges and plates. Bezel and slider lock screws allow the dial setting and jaw position to be secured when a measurement needs to be retained.
For a smaller metric range, the Mitutoyo 505-743 provides a 0–8" measuring range in the supplied Series 505 comparison data.

Who This Product Is Best For
The Mitutoyo 505-746 is suitable for machinists, quality inspectors, maintenance technicians, fabrication workshops and other users who need a mechanical caliper with a 12" measuring capacity.
Its standard hardened stainless steel jaws provide a general-purpose configuration for mixed workshop applications. The extended range is useful when measuring larger components that exceed the capacity of shorter calipers.
The 0.1" per revolution configuration provides controlled jaw travel while retaining a 0.001" dial graduation. This can be useful when the measurement requires frequent positioning and fine reading across the extended range.
How to Use the Mitutoyo 505-746
-
Clean the measuring jaws and workpiece before measurement.
-
Close the jaws gently and check the dial zero. Adjust the bezel if necessary and secure it.
-
Open the jaws beyond the feature being measured.
-
Position the caliper squarely against the workpiece and close the jaws gently using the slider.
-
Read the main dimension from the beam and the fine value from the dial according to the 0.001" graduation.
-
Use the slider lock when the jaw position needs to be retained for reading or recording.
-
Clean the measuring surfaces after use and store the caliper in its fitted plastic case.
When measuring toward the full 12" range, support the instrument appropriately and keep the beam aligned with the workpiece to help maintain consistent contact.
