Mitutoyo 155-905 Telescoping Gauge Set, 8 to 150 mm

Description

The Mitutoyo 155-905 Telescoping Gauge Set is a 6-piece, analog, metric tool used for taking precise internal diameter measurements of holes, slots, and bores. Each gauge has a spring-loaded plunger that expands within the bore and is then locked in place with a knurled screw. The final diameter is measured with an outside micrometer after the gauge is removed.

Key features

• Constant spring force: The gauges have hardened steel plungers powered by a balanced, spring-loaded mechanism that ensures smooth operation. This constant spring force provides uniform contact pressure, which is critical for consistent and accurate readings.
• Hardened contacts: The contact points on the plungers are hardened and ground to a radius, which ensures a true fit and accurate measurements inside bores, holes, and slots.
• Self-centering: The plungers are designed to self-center within the bore, minimizing errors from misalignment during measurement.
• Knurled handle and lock: A knurled screw on each gauge locks the plungers in place once the measurement is set. The knurled handle also provides a confident grip and is resistant to rust.
• Satin chrome finish: The rust-resistant satin chrome finish on the gauges provides additional durability and protects against corrosion.
