Cyclus Tools is a specialist in crafting high-quality tools designed for professional bicycle repair shops, equally suitable for hobby technicians. These durable tools, manufactured in Europe, undergo rigorous quality checks to ensure longevity. In addition to their extensive tool range, Cyclus Tools offers workshop furniture and cosmetic care products. As a leading bicycle tool manufacturer, Cyclus Tools constantly evolves its products to align with the dynamic industry landscape. One notable product is the Cyclus Tools Cutting and Milling Tool for T-47 threads, specifically engineered for re-cutting bottom bracket threads and milling bottom bracket shells. This versatile tool seamlessly transitions between tasks, eliminating the need for tool changes and ensuring a flawless 100% parallel face milling of the bottom bracket shell threads. Key advantages include the convenience of using a single tool for both processes and precise guidance leading to parallel milled housing sides. This tool is essential for T47 bottom bracket assembly, accommodating BSA and large-volume bottom bracket shells with a 46 mm diameter, such as PressFit 30, BBRIGHT PressFit, 386EVO, and OSBB. It facilitates the professional preparation of existing housings with a flat milled surface, ensuring the secure installation of bearing shells akin to BSA standards. However, it's crucial to note that the cutter requires a metal surface for proper functioning, and not all frames are suitable for this conversion. Users are advised to consult the frame manufacturer for compatibility. Special attention is needed when working with frames featuring glued-in or laminated metal sleeves during the thread-cutting process, as they are subjected to high torsional forces. The tool markings, such as "R" for right (clockwise) or "L" for left (counterclockwise), should be interpreted in relation to the tool itself, not its application on the bicycle, as there is no fixed reference system in that context. Users are strongly encouraged to exercise caution and consult the manufacturer for frame suitability in this type of conversion. Part number: 720151 Barcode: 8590831360074 Product code: CYC 720151
