Mitutoyo 50-1000mm Tubular Micrometer

Description Product Overview When you need to accurately measure massive internal diameters, deep engine cylinders, or large structural spans, standard tools simply cannot bridge the gap. The Mitutoyo 50-1000mm Tubular Inside Micrometer is the ultimate heavy-duty metrology solution for large-scale machining and inspection. Massive 1-Meter Capacity: This comprehensive kit covers a staggering measuring range from 50mm all the way up to 1000mm (approx. 2″ to 40″). By combining the precision micrometer head with the interchangeable extension rods, you can custom-build the exact length required for your specific bore. Rigid Tubular Design: When spanning a full meter, solid rods will droop and sag under their own weight, destroying your measurement accuracy. Mitutoyo engineers these extension rods as hollow tubes, providing incredible structural rigidity while keeping the tool lightweight and easy to handle during delicate sweeping operations. Flawless Joints: The extension rods connect with exceptionally precise fitting mechanisms to ensure that stacking multiple rods together does not introduce cumulative parallel errors. Carbide-Tipped Precision: The measuring faces are carbide-tipped for superior durability, ensuring the tool maintains its strict 0.01mm resolution accuracy even after years of sliding against rough cast iron cylinders or steel pipe. Condition Used (Very Good Condition / Complete in Box). This large-scale inside micrometer is in very good used condition. It has been treated with the utmost respect in a professional machining environment. Mechanical Integrity: The micrometer head thimble rotates with legendary Mitutoyo buttery smoothness, and the locking clamp engages securely. The tubular extension rods are straight, undamaged, and the connection threads are clean. Included Setup: The entire kit comes safely housed in its original Mitutoyo factory fitted plastic box, keeping all the rods perfectly organized and protected from shop floor moisture. Brand Information Mitutoyo Corporation (Japan) is the undisputed global benchmark for dimensional metrology. Their large-scale internal measuring instruments are heavily sought after by master engine builders, aerospace machinists, and heavy-industry inspectors because they maintain laboratory-grade accuracy over massive spans where budget brands flex and fail.
