Mitutoyo 511-437-20 Series 511 2-Point Inside Measuring Instrument Bore Gauge for Blind Holes, 50-150 mm Range, 0.001 mm Graduation, with Indicator

The Mitutoyo blind hole bore gage is ideal for measuring the inner dimensions at the bottom of blind bores and holes with an accuracy of 4 µm. Interchangeable anvils constructed of alloy steel allows for measurements of a wide range of bore diameters. A pendulum guide structure permits the slide of the gage for easier measurements without sacrificing accuracy. A two-point contact system detects geometry anomalies such as ovalness and taper.
