Mitutoyo 511-440-20 Mechanical Blind Hole Bore Gauge, 2-6" Range, Dial

Description

The Mitutoyo 511-440-20 Mechanical Blind Hole Bore Gauge is a two-point dial bore gauge designed to accurately measure the internal diameter (ID) of blind holes at or near the bottom. It has a measuring range of 2 to 6 inches, with a graduation of 0.0001 inches. The gauge comes with a dial indicator, interchangeable anvils, and spacers.

Key features

• Blind-hole measurements: The flat-bottomed head enables accurate measurement of the internal diameter close to the bottom of blind holes.
• High accuracy: The gauge has a graduation of 0.0001" and an accuracy of 0.0002".
• Carbide-tipped contact points: The measuring faces are made with durable, wear-resistant carbide for extended tool life and accuracy.
• Ergonomic grip: A large, hollow grip is designed to reduce the transfer of heat from the operator's hand, minimizing its effect on high-accuracy measurements.
• Pendulum guide structure: This design improves the sliding action of the gauge for easier and more precise measurements.
• Interchangeable anvils: The gauge set includes a range of interchangeable, alloy-steel anvils and spacers to cover its full measuring range.
• Two-point contact system: This system can detect bore geometry problems such as ovalness and taper.
• Dial indicator protection: A cover protects the dial indicator from damage.
