Mitutoyo 505-744 | Dial Caliper | Series 505 | OD Carbide Tipped Jaws | Graduation 0.001 Inch | Accuracy ±0.001 Inch | Range 0 to 6 Inch | Weight 175 g
Part No. 505-744 | Range 0–6" | Graduation 0.001" | Accuracy ±0.001"
Product Overview
The Mitutoyo 505-744 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 applications.
The 505-744 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.
This model has a 0.2" range per revolution, while each dial division represents 0.001". The faster jaw travel can be useful when moving across larger dimensions within the 0–6" measuring range. Bezel and slider lock screws allow the dial setting and jaw position to be retained when required.
The 505-744 features carbide-tipped outside jaws. Carbide provides a wear-resistant measuring surface for applications involving hardened, cast or abrasive workpieces, helping protect the OD measuring faces during repeated use.
For a larger measuring range, the Mitutoyo 505-750 covers 0–12".

Who This Product Is Best For
The Mitutoyo 505-744 is suitable for machinists, quality inspectors, maintenance technicians, fabrication workshops and dimensional inspection teams measuring components up to 6".
Its carbide-tipped outside jaws are useful where OD measuring faces are exposed to harder or abrasive workpieces. The mechanical dial design also suits workshops that prefer a battery-free instrument for routine dimensional measurements.
The 0.2" range per revolution allows the slider to traverse the measuring range efficiently, while the 0.001" dial graduation provides the specified measurement resolution for inspection work.
How to Use the Mitutoyo 505-744
-
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 measuring 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 505-744 measure?
The 505-744 measures outside dimensions, inside dimensions, depths and steps across a 0–6" range.
How accurate is the Mitutoyo 505-744?
The specified accuracy is ±0.001".
What is the graduation of the 505-744?
The dial graduation is 0.001", with a 0.2" range per revolution.
Does the Mitutoyo 505-744 require batteries?
No. The 505-744 is a mechanical dial caliper and does not require batteries for operation.
Does the 505-744 have carbide jaws?
Yes. The 505-744 has carbide-tipped outside jaws. The supplied specification does not identify the inside jaws as carbide-tipped.
What is the difference between the 505-744 and 505-738?
Both models cover a 0–6" range and have carbide-tipped outside jaws. The 505-744 is specified with 0.001" graduation, ±0.001" accuracy and 0.2" per revolution, while the 505-738 is specified with carbide-tipped OD and ID jaws and 0.1" per revolution.
What is the difference between the 505-744 and standard-jaw 0–6" models?
The 505-744 uses carbide-tipped outside jaws, while standard-jaw models use conventional hardened stainless steel measuring jaws. Carbide OD jaws can be useful where the measuring faces are exposed to harder or abrasive workpieces.
What does 0.2" per revolution mean on the 505-744?
It means the caliper's jaw travel associated with one complete dial revolution is 0.2". The individual dial graduation remains 0.001".
