Mitutoyo 8-10mm Digital Holtest Micrometer

Description Product Overview This Mitutoyo Digital Holtest is a premium three-point internal micrometer designed for the rapid and highly accurate measurement of small bores in the 8mm to 10mm range. Three-Point Contact: Unlike two-point calipers that can rock inside a hole, this gauge uses three self-centering anvils spaced at 120°. This geometry automatically aligns the tool squarely within the bore, ensuring you capture the true diameter every single time. Digimatic Readout: The digital LCD screen provides an instant, error-free reading. This completely eliminates the need to squint at tiny mechanical vernier scales in poorly lit shop environments, speeding up your inspection process. Ratchet Stop: Equipped with a constant-force ratchet mechanism on the thimble. This ensures the exact same measuring pressure is applied to the anvils during every use, guaranteeing repeatable results regardless of the operator’s touch. Small Bore Capability: Measuring accurately under 10mm is notoriously difficult; this specialized Holtest makes it a fast and reliable process for critical internal dimensions. Condition Used (Bare Tool / Tested & Accurate). This Holtest is in used condition and is being sold as a bare tool. Included: This listing is for the micrometer only. It does not come with a storage case, factory paperwork, adjustment spanners, or a setting ring. Tested & Verified: Despite lacking its original accessories, this gauge has been personally tested and calibrated in-house against a known 8mm master setting ring. Its mechanical action is smooth, and its dimensional repeatability is spot-on, making it a reliable addition to any working shop. Brand Information Mitutoyo Corporation (Japan) is the undisputed global benchmark for dimensional metrology. Their “Holtest” series is widely considered the best internal bore measurement system in the world, prized for its ability to hold microscopic tolerances and maintain flawless electronic readouts even after years of shop-floor use. 1 Specifications FeatureSpecificationBrandMitutoyo (Japan)TypeDigital Holtest (Three-Point Internal Micrometer)Measuring Range8mm – 10mmThimble TypeRatchet StopIncluded AccessoriesNone (Bare tool only)ConditionUsed / In-house Tested & Calibrated Keywords Mitutoyo digital holtest, 8-10mm bore gauge, internal micrometer, three point micrometer, small bore gauge, Digimatic holtest, machinist tools, Japanese metrology, bare tool micrometer.
