Angular thread cutting gauge

With the help of the thread cutting angle gauge, you can check and adjust the cutting angle of threads correctly—especially when working with threads that have a 55° geometry (e.g., Whitworth thread (WW) or RG threads). It is a tool for checking threads and adjusting the sharpening or milling angle of thread cutting tools. Typically used in the manufacture and maintenance of turning/workpiece threads, it is suitable for both external and internal thread inspection. This tool is designed for professionals in machining, maintenance, and repair who work with British/non-metric threads (Whitworth, RG). It ensures that the threading tool is at the correct angle before cutting threads or when inspecting the geometry of the finished thread, helping to maintain accuracy and compliance with thread standards.
