Industrial GWO TOOL 3-4 UNC Hand Tap 6 Flute HS GH9 HSS 4140 Hand Tap

The GWO TOOL Industrial 3-4 UNC Hand Tap is a six-flute tool designed to cut internal UNC threads with robust, repeatable performance for metalworking tasks. It is described as made from high-speed steel (HSS) with GH9 and 4140 steel references, signaling a focus on hardness and wear resistance suitable for industrial tapping. The 3-4 UNC designation indicates the target thread size range, enabling tapping of standard coarse-thread holes in ferrous and nonferrous metals. The six-flute geometry supports efficient chip evacuation, helping to reduce clogging and produce cleaner thread profiles during manual tapping. This hand tap is positioned for use in workshop environments, maintenance, fabrication, and repair work where durable threading tools are required. By combining HSS characteristics with steel-grade considerations, the tool aims to deliver long service life under repeated tapping cycles, making it a suitable choice for technicians and machinists working with UNC-threaded fasteners.
