Description Product Overview When you move into heavy industrial machining, large-scale engine building, or massive hydraulic cylinder repair, measuring tools get incredibly expensive. Buying four individual micrometers to cover the 300mm to 400mm range is a massive investment. The Mitutoyo 104-142 Interchangeable Anvil Micrometer completely solves this by giving you a single, highly rigid frame that covers the entire 100mm spread. Interchangeable Anvil System: This micrometer features a heavy-duty, baked-enamel frame equipped with an interchangeable anvil system. By simply swapping out the fixed anvils, you can instantly configure the micrometer to measure 300-325mm, 325-350mm, 350-375mm, or 375-400mm. Included Setting Standards: Every time you swap an anvil, you need to re-zero the tool. Please note that while a brand-new factory kit includes four standards, this specific kit includes two factory setting standards (believed to be 350mm and 400mm). You can easily master the micrometer for those specific sizes or use your own shop gauge blocks/standards for the remaining anvil ranges. Carbide-Tipped Accuracy: The measuring faces feature premium carbide tips, ensuring maximum wear resistance and strict adherence to Mitutoyo’s legendary accuracy standards, even when measuring abrasive castings or hardened steel shafts. Constant Force Ratchet: Sweeping a massive 400mm micrometer requires a delicate touch. The built-in ratchet stop ensures a uniform, repeatable measuring force is applied every single time, completely removing operator “feel” from the equation. Condition Used (Great Condition / Worn Box / Original Papers). This heavy-duty micrometer kit has seen professional shop use but remains in great functional and mechanical condition. The Micrometer & Kit: The micrometer frame, the thimble mechanism, and the four interchangeable anvils are all in fantastic shape. The thimble rotates with legendary Mitutoyo smoothness, and the anvils lock in securely. It includes all of its original factory paperwork, including the inspection certificates and instruction manuals. The Wooden Box: In the spirit of total transparency, the large original wooden storage box is quite worn out on the outside. Moving heavy wooden cases around a machine shop inevitably leads to scuffs, scratches, and wear. However, the latches still work, and it continues to do its most important job: keeping this massive, precision instrument safely protected from shop floor hazards. Brand Information Mitutoyo Corporation (Japan) is the undisputed global benchmark for dimensional metrology. Their 104-series interchangeable anvil micrometers are heavily favored by large-scale manufacturing facilities, oil-field repair shops, and heavy diesel mechanics because they provide an incredibly rigid, reliable, and cost-effective way to measure massive diameters.
