Mitutoyo 505-747 | Dial Caliper | Series 505 | OD Carbide Tipped Jaws | Graduation 0.001 Inch | Accuracy ±0.002 Inch | Range 0 to 12 Inch | Weight 370 g
Part No. 505-747 | Range 0–12" | Graduation 0.001" | Accuracy ±0.002"
Product Overview
The Mitutoyo 505-747 is a Series 505 mechanical dial caliper with a 0–12" measuring range, 0.001" graduation and ±0.002" specified accuracy. It provides outside, inside, depth and step measurement in one instrument, making it suitable for general dimensional inspection of large components.
This version features carbide-tipped outside jaws. The carbide measuring faces provide increased resistance to wear when repeatedly checking hardened, cast or abrasive components, helping maintain the condition of the outside measuring surfaces during regular workshop use.
The mechanical dial provides a direct analog reading without batteries. On the 505-747, one dial revolution corresponds to 0.1", while each dial division represents 0.001". This provides a fine inch-based reading for routine machining, fabrication, maintenance and inspection work.
The hardened stainless steel beam and caliper construction are suited to demanding workshop environments. The Series 505 dial mechanism is designed for smooth slider movement and shock protection, while the bezel and slider locking screws allow the operator to retain the dial setting and measurement position when required.
The 0–12" range provides useful capacity for larger parts such as flanges, housings, shafts and plates. When measuring at the upper end of the range, keep the caliper square to the feature and support the instrument appropriately for consistent contact.
For a smaller measuring range, the Mitutoyo 505-737 provides a 0–8" range.

Who This Product Is Best For
The Mitutoyo 505-747 is suitable for machinists, quality inspectors, maintenance technicians, fabrication teams and dimensional-inspection departments working with components up to 12".
The carbide-tipped outside jaws are particularly useful for applications involving repeated outside measurement of hardened, cast or abrasive materials. The 0.001" graduation and mechanical dial make the instrument suitable for inch-based workshop and inspection applications where battery-free operation is preferred.
How to Use
-
Clean the measuring jaws and the component before measurement.
-
Close the jaws gently and check the dial zero.
-
Rotate the bezel to align the pointer with zero if adjustment is required, then secure the bezel lock.
-
Open the jaws beyond the dimension being measured.
-
Position the caliper squarely against the workpiece and close the jaws gently using the thumb roller.
-
For outside measurement, ensure the carbide-tipped OD faces make proper contact with the component.
-
For inside measurement, position the appropriate inside jaws within the bore or opening.
-
Use the depth function for recessed features and the step surfaces for step measurements.
-
Read the beam and dial indication according to the 0.001" graduation.
-
Lock the slider if the measurement needs to be retained while removing the caliper from the part.
-
Check zero again after measurement and clean the instrument before storage.
Frequently Asked Questions
What can the Mitutoyo 505-747 measure?
The 505-747 measures outside and inside dimensions, depths and steps over a 0–12" range.
What is the graduation of the Mitutoyo 505-747?
The dial caliper has a 0.001" graduation, with one complete dial revolution corresponding to 0.1".
How accurate is the Mitutoyo 505-747?
The specified accuracy for the 0–12" model is ±0.002".
What type of jaws does the 505-747 have?
The 505-747 has carbide-tipped outside measuring jaws. The inside jaws are not specified as carbide-tipped for this order number.
Why use carbide-tipped OD jaws?
Carbide provides increased resistance to wear when the outside measuring faces are repeatedly used on hardened, cast or abrasive components.
Does the Mitutoyo 505-747 require batteries?
No. It is a mechanical dial caliper and does not require batteries for normal operation.
What is the difference between the 505-747 and 505-748?
Both models have a 0–12" range, 0.001" graduation and 0.1" per revolution. The 505-747 has carbide-tipped OD jaws, while the 505-748 has carbide-tipped OD and ID jaws.
Is the Mitutoyo 505-747 suitable for depth measurement?
Yes. The caliper provides depth measurement in addition to outside, inside and step measurement.
