SERIES 251 -01
A dial bore gauge is a precision instrument used to measure the internal diameter of holes, cylinders, or bores with high accuracy. It consists of a measuring head with adjustable anvils and a dial indicator that displays the measurement. Dial bore gauges are commonly used in machining, automotive, and industrial applications to ensure that bored holes meet specific dimensional tolerances.

Advantages of a Dial Bore Gauge
- High Precision: Provides highly accurate internal diameter measurements, essential in precision engineering.
- Ease of Use: The dial indicator allows for easy and quick reading of measurements, reducing the likelihood of errors.
- Durability: Dial bore gauges are robust and can withstand regular use in industrial environments.
- Versatility: With interchangeable anvils and spacers, a single dial bore gauge can measure a wide range of bore sizes.
Usage Procedure
- Preparation: Select the appropriate anvils and spacers for the bore size you intend to measure. Attach them to the measuring head and ensure the dial indicator is zeroed using a master gauge or standard.
- Insert the Gauge: Insert the bore gauge into the bore or hole to be measured. Ensure that the anvils are fully inside the bore.
- Center the Gauge: Gently rock the bore gauge back and forth within the bore to ensure the anvils are aligned and the gauge is centered.
- Read the Dial: Observe the needle's movement on the dial indicator. The smallest reading, which occurs when the gauge is perfectly aligned and centered, represents the bore's diameter.
- Compare with Specification: Compare the reading against the required tolerance to determine if the bore is within specification.
