Mitutoyo 505-738 | Dial Caliper | Series 505 | ID/OD Carbide Tipped Jaws | Graduation 0.001 Inch | Accuracy ±0.001 Inch | Range 0 to 6 Inch | Weight 175 g
Part No. 505-738 | Range 0–6" | Graduation 0.001" | Accuracy ±0.001"
Product Overview
The Mitutoyo 505-738 is a Series 505 mechanical dial caliper designed for measuring outside, inside, depth and step dimensions across a 0–6" range. It provides ±0.001" accuracy with 0.001" graduation and operates without batteries, making it suitable for routine dimensional inspection in machining, fabrication, maintenance and quality-control environments.
The 505-738 uses Mitutoyo's redesigned Series 505 dial movement for smooth slider operation and high shock protection. Its hardened stainless steel construction is suited to regular shop-floor use, while the analog dial provides a direct mechanical reading.
The dial has a 0.1" range per revolution, with each division representing 0.001". This provides a clear mechanical indication while avoiding the need for a battery-powered display. Bezel and slider lock screws allow the dial setting and jaw position to be retained when required.
Both the outside and inside jaws are carbide-tipped. Carbide provides wear-resistant measuring faces for applications involving hardened, cast or abrasive workpieces, helping protect the OD and ID measuring surfaces during repeated use.
For a larger measuring range, the Mitutoyo 505-739 covers 0–8".

Who This Product Is Best For
The Mitutoyo 505-738 is suitable for machinists, quality inspectors, maintenance technicians, fabrication workshops and dimensional inspection teams measuring components up to 6".
Its carbide-tipped outside and inside jaws are useful where measuring faces may be exposed to hardened, cast or abrasive materials. The battery-free mechanical design also suits workshops that prefer a straightforward analog measuring instrument for routine inspection.
With four measurement functions in one tool, the 505-738 can be used for outside and inside dimensions as well as depth and step measurements, reducing the need to change between different measuring instruments during general inspection work.
How to Use the Mitutoyo 505-738
-
Clean the measuring jaws and workpiece before measurement.
-
Close the jaws gently and check the dial position. Adjust the bezel to zero when required and secure it with the bezel lock screw.
-
Open the jaws beyond the feature being measured.
-
Position the appropriate outside or inside jaws squarely against the workpiece.
-
Close the jaws gently using the slider/thumb roller until proper contact is established.
-
Read the beam scale together with the dial indication to determine the measurement.
-
Use the slider lock screw when the jaw position needs to be retained for inspection or recording.
-
Clean the caliper after use and return it to its fitted plastic case.
For repeatable measurements, keep the measuring surfaces clean, avoid excessive measuring force and maintain proper alignment between the caliper and workpiece.
Frequently Asked Questions
What can the Mitutoyo 505-738 measure?
The 505-738 measures outside dimensions, inside dimensions, depths and steps across a 0–6" range.
How accurate is the Mitutoyo 505-738?
The specified accuracy is ±0.001".
What is the graduation of the 505-738?
The dial graduation is 0.001", with a 0.1" range per revolution.
Does the Mitutoyo 505-738 require batteries?
No. The 505-738 is a mechanical dial caliper and does not require batteries for operation.
Does the 505-738 have carbide jaws?
Yes. Both the outside and inside jaws are specified as carbide-tipped.
What is the difference between the 505-738 and 505-744?
Both models cover 0–6" and have 0.001" graduation with carbide-tipped outside jaws. The 505-738 also has carbide-tipped inside jaws and uses 0.1" per revolution, while the 505-744 has carbide-tipped outside jaws and uses 0.2" per revolution. The supplied accuracy is ±0.001" for both models.
What is the difference between the 505-738 and 505-736?
Both are 0–6" Series 505 dial calipers with carbide-tipped outside jaws and 0.1" per revolution. The 505-738 is specified with carbide-tipped outside and inside jaws, while the 505-736 is specified with carbide-tipped outside jaws.
What is the difference between the 505-738 and standard-jaw 0–6" models?
The 505-738 uses carbide-tipped outside and inside jaws, whereas standard-jaw versions use conventional hardened stainless steel measuring jaws. The carbide configuration provides increased resistance to wear when measuring harder or abrasive workpieces.
