The #38 thread size with a 1-7/16 inch flute length carbide end mill is an essential tool for machinists working on aluminum, brass, or stainless steel material - providing precision threading at high speeds. The 90 degree helix angle enhances chip clearance efficiency, improving the overall accuracy and finish quality of machined parts while reducing the risk of thermal damage to delicate materials. Typically used in machining applications such as gears or screws production lines where precision threading matters, this tool allows users to create smooth yet aggressive threads without breaking under pressure, meeting the standards required in toolmaking industries for reliable assembly solutions.
