The Mitutoyo 511-803 micrometer head bore gauge and interchangeable anvils greatly expand the gauge’s measurement range with high accuracy. The Mitutoyo bore gauge with a micrometer head (no indicator) delivers a wide range of bore measurement capabilities at high accuracy to 2µm. Interchangeable anvils constructed of alloy steel attach to the micrometer head for accurate dimensional setting. The anvils feature a carbide-tipped ball for better measurement reliability and longevity.
