About Johs. Boss (JBO)
Johs. Boss GmbH & Co. KG (brand JBO), based in Albstadt, develops and manufactures precision tools for the production and inspection of threads. The product range includes high-performance thread mills, helical-interpolation and bell-type thread mills, combination tools, PCD, CVD-D and PcBN tools, high-performance taps, thread rolling dies as well as precision thread gauges, complemented by linear units and rotary units. The carbide tools with an ultra-fine-grain substrate and high-performance coating are designed for steel and non-ferrous metals and are available from stock in thread types such as M, G, UNC, UNF, MJ, UNJC and UNJF. The warehouse covers 22,000 common thread dimensions and tolerances; for quality assurance, works calibration certificates are issued. With its own aerospace portfolio, the company serves in particular the aerospace industry, alongside mechanical engineering and toolmaking, and delivers worldwide.
