Description Product Overview The NSK 1500mm Tubular Inside Micrometer is a vintage, heavy-duty measuring set designed for checking large internal diameters such as cylinder bores, pipes, and casings. Tubular Construction: Uses hollow tubular extension rods. This design provides the necessary rigidity to measure across 1.5 metres without the sagging weight associated with solid rods. Unique Configuration: Unlike standard sets that come with a single measuring head, this specific set features 3 Micrometer Heads. This allows for multiple setups or redundancy without needing to constantly disassemble the head from the rods. Wide Capacity: With the included extensions, this set covers a massive range (up to 1500mm), making it an essential tool for heavy equipment repair and industrial maintenance. Condition Used (Vintage / Great Condition). This is a “User Set” in great mechanical condition. Cosmetics: It shows signs of use and “patina” consistent with a vintage tool, but there is no damage that affects functionality. The micrometer heads move smoothly. Configuration Note: This is a mixed set. It is missing the original 150mm and 200mm rods. However, it includes an extra 12mm spacer and an extra 200mm rod to help bridge the gaps. Despite the mismatch, it remains a fully functional kit offering a wide range of measurement options. Brand Information NSK (Japan) is a legendary name in precision engineering. While best known today for their world-class bearings, their vintage measuring tools are highly prized by machinists for their build quality, often rivalling Mitutoyo and Starrett from the same era.
