Mitutoyo 511-931-20 Standard Bore Gauge Set, .0005"

Description

The Mitutoyo 511-931-20 is a standard dial bore gauge set that measures the internal diameter (ID) of bores from 0.7 to 6.0 inches. The set provides high accuracy and repeatability, and includes three bore gauges, 26 interchangeable anvils, 10 spacers, and a protective carrying case.

Key features

• High accuracy and repeatability: The set is capable of high-precision measurements with an accuracy of 0.00008 inches and a repeatability of 0.00002 inches. This is achieved through its two-point contact system, which also detects potential geometry issues like ovality and taper.
• Automatic self-centering: A pendulum guide structure allows the gauge to automatically self-center within a bore, which helps improve measurement consistency.
• Interchangeable components: The set includes interchangeable anvils (26 total, plus a sub-anvil) and 10 spacers. This allows the user to configure the gauge for a wide range of bore sizes, from 0.7 to 6.0 inches.
• Protection for dial indicator: The included Mitutoyo dial indicator is protected by a rugged cover, helping to prevent damage in a workshop environment. 
• Carbide-tipped contact points: The interchangeable anvils feature carbide-tipped measuring faces, which are highly durable and wear-resistant for extended use.
• Reduced heat transfer: The handle is hollow, which reduces the transfer of heat from the operator's hand to the gauge by 50%, maintaining measurement stability and accuracy.
• Protective case: The entire set comes supplied in a fitted plastic case for secure storage and transport.
