depth gage
A technician uses a depth gage to measure the depth of a small hole in a metal block.
Noun: A measuring instrument specifically designed to determine the vertical distance from a reference surface to the bottom of a cavity, such as a hole, groove, or recess.
A depth gage is a precision tool used in machining, carpentry, engineering, and quality control to measure the depth of features that are not easily measured with a standard ruler or caliper. It ensures parts meet specified dimensional tolerances.
- The machinist used a depth gage to verify the depth of the drilled hole was exactly 10 millimeters.
- Before assembling the parts, check the groove's depth with a depth gage.
- A digital depth gage provides a more precise and easier-to-read measurement than a traditional dial version.
- "To take a depth gage reading": The act of using the instrument to obtain a measurement.
- The inspector took a depth gage reading from three points along the channel.
- In metrology, a depth gage is a fundamental tool for dimensional inspection, often used alongside micrometers and calipers.
- Depth gauge: The more common modern spelling, identical in meaning and function to "depth gage."
- Depth micrometer: A specific, highly precise type of depth gage that uses a micrometer mechanism for measurement.
- Dial depth gauge: A depth gage that uses a dial indicator to display the measurement.
- Depth probe
- Depth measurement tool
The term "depth gage" uses an older spelling of "gauge." In contemporary technical English, "depth gauge" is the predominant and recommended spelling, though "gage" is still recognized, particularly in some historical or specialized American engineering contexts. Both forms refer to the same instrument.
