Mitutoyo 511-439-20 Series 511 Blind Hole Bore Gauge with protective cover, 1.4 to 2.4", inch

Description

The Mitutoyo 511-439-20 Series 511 Blind Hole Bore Gauge is an analog tool designed for taking precise internal diameter measurements near the bottom of blind bores and holes. This specific model has a measurement range of 1.4 to 2.4 inches and features a dial indicator with a 0.0001-inch graduation. The "protective cover" refers to a rugged casing that protects the dial indicator.

Key features

• Measurement capability: Features a flat-bottomed head to measure inside diameters close to the bottom of blind holes.
• High accuracy: It has a high-range accuracy of 0.00016 inches (4µm) and a repeatability of 0.00004 inches (1µm), according to Global Test Supply.
• Precision and stability: A pendulum guide structure allows the gauge to slide easily for measurements without sacrificing accuracy, and a two-point contact system helps detect geometric anomalies like ovality and taper.
• Durable contact points: The interchangeable anvils have carbide-tipped measuring faces for high durability and wear resistance.
• Reduced heat transfer: The large, hollow grip is designed to reduce the effect of the operator's body heat on high-accuracy measurements.
• Set inclusions: The gauge is supplied with six interchangeable anvils and four spacers, and it comes in a fitted plastic case.
• Indicator protection: A rugged cover protects the dial indicator from damage.
