Mechanical Holtest (Type II) Three-Point Internal Micrometer Complete Set
The Mitutoyo Holtest (Type II) mechanical three-point internal micrometer complete set includes holtests capable of measuring inside dimensions from 12mm to 200 (metric set) and .5” to 8” (inch set).
Features & Benefits
The Mitutoyo mechanical Holtest internal micrometer set includes complete gages (micrometer head units and measuring heads) for each size. Three alloy steel anvils evenly spaced at 120° for true alignment of the axis bore for accurate, easily repeatable measurements. Hardened steel spindles with a carbide ball and cones with a carbide pin ensure accuracy and durability when extending and retracting the anvils. The holtests ratchet stop mechanism provides a constant measuring force on the hardened steel spindle to ensure accurate, even measurements.
