Starrett Telescoping Gage Range

Starrett telescoping gages, also called telescoping gauges, are precision transfer measuring tools. They are used to measure the inside diameter of bores, holes, slots and grooves. Machinists, toolmakers, engine builders and inspectors use them to check dimensions that a standard caliper or micrometer can't reach directly.

Key Features:

• Spring-loaded telescoping plungers adjust to the bore and lock in place so the measurement can be transferred and read with a micrometer
• Locking knurled handle holds the setting after the gage is removed from the bore
• Hardened, precision-finished contact surfaces are built for repeatable accuracy and wear resistance
• Swivel head allows easy positioning and a consistent feel in the bore
• Handles are designed for comfortable control during setup and measuring
• Available in multiple ranges to cover a wide variety of bore sizes

Starrett has a long reputation for precision measuring tools made to demanding standards. Use these gages for engine cylinder bores, bushings, valve guides, lifter bores, bearing housings and other internal machining work. They suit shop, automotive machining and tool room use. Pair them with an outside micrometer to get an accurate inside dimension.
