Telescopic Gauges are precision measuring tools designed to measure the internal diameter of bores, slots, and recesses. They feature spring-loaded plungers that expand to fit the internal surface, which can then be locked and measured with a micrometer or caliper for accurate readings.
Key Characteristics:
Spring-Loaded Plungers: Expand smoothly to match the internal size of the bore or recess.
Locking Mechanism: Allows the gauge to retain its expanded size for measurement outside the workpiece.
Range of Sizes: Typically supplied in sets covering different bore diameters for versatility.
Durable Construction: Made from hardened steel for accuracy and long service life.
High Accuracy: Used with micrometers or calipers to achieve precise internal measurements.
Common Uses:
Machining: Checking bore diameters during or after turning, milling, or drilling.
Inspection: Verifying internal dimensions of components in workshops and quality control labs.
Maintenance: Measuring wear in engine cylinders, bushings, and other round components.
