A Telescopic Gauge is a precision measurement tool used to measure the internal diameter or bore of holes, slots, or grooves. It works by expanding its telescopic arms to fit inside a bore or cavity, and then the measured dimension is transferred to a micrometer or caliper for accurate reading. This tool is widely used in machining, metalworking, and engineering for measuring internal dimensions in hard-to-reach areas.
- 6 gauges per set
- For quick measurement of inside diameter of holes and width of slots
- Satin chrome finish
Advantages of a Telescopic Gauge:
- Accurate Measurement: Provides a reliable method of measuring internal diameters, especially for hard-to-reach areas where other tools may not fit.
- Durable and Long-Lasting: Made from high-quality materials like hardened steel for durability in industrial use.
- Self-Centering Design: Ensures precise alignment for more accurate measurements.
- Versatile: Available in different sizes to measure a wide range of bore diameters.
A Telescopic Gauge is an indispensable tool for accurately measuring internal diameters of bores and cavities in various machining, metalworking, and engineering applications. Its self-centering telescopic arms, durable construction and ease of use make it a valuable instrument for ensuring precise and reliable internal measurements.

Applications:
-
Machining and Metalworking:
- Bore Measurement: Telescopic gauges are used to measure the internal diameter of bores and cylindrical cavities, such as in engine cylinders, bearing housings, and other precision-machined parts.
- Tool Setup: Essential for setting up machine tools and ensuring that bores and holes meet exact specifications.
-
Quality Control and Inspection:
- Dimensional Inspection: Commonly used in quality control processes to verify that internal diameters of machined parts meet specified tolerances.
- Part Verification: Useful for checking the dimensional accuracy of various components in manufacturing and assembly.
-
Automotive and Aerospace:
- Engine Component Inspection: Used to measure bores in engine blocks, cylinders, and other critical components in automotive and aerospace applications, ensuring that they meet strict tolerance standards.
-
Tool and Die Making:
- Internal Feature Measurement: Useful for measuring the internal features of tools, dies, and molds to ensure they match the desired specifications.
Key Features:
-
Telescopic Arms:
- Spring-Loaded Mechanism: The gauge has two spring-loaded telescopic arms that expand to fit the internal surface of a bore or hole. The arms retract or extend when the locking mechanism is released, making it easy to fit the gauge into place.
- Self-Centering: The telescopic arms are designed to center themselves within the bore, ensuring a more accurate measurement by aligning with the hole’s center.
-
Measuring Range:
- Various Sizes: Telescopic gauges come in different sizes to accommodate various bore diameters.
-
Locking Knob:
- Secure Measurement: Once the arms are expanded to fit the bore, the user tightens the locking knob to hold the telescopic arms in place. This locking mechanism ensures that the measurement remains stable and precise when the gauge is removed for reading.
-
Durable Construction:
- Hardened Steel Construction: The gauge is typically made from durable materials such as hardened steel, making it robust enough to withstand repeated use in industrial environments.
- Polished Surface: The polished arms ensure smooth expansion and retraction without damaging the internal surfaces of the bore being measured.
-
Transfer to Micrometer or Caliper:
- Indirect Measurement: Once the telescopic gauge is locked in position, the gauge is removed from the bore, and the expanded distance is measured using an outside micrometer or caliper. This indirect method ensures high accuracy in measuring the internal dimensions.
