Westward Threading Tap 5TWN0 The Westward 5TWN0 is made of high-speed steel, this little spiral-point tap has a titanium nitride (TiN) coating for added hardness and longer tool life. It is intended to cut right-hand threads in through-holes and has a total length of slightly less than 54 mm. During cutting, the spiral-point shape forces chips forward, minimizing accumulation and enabling smoother, more effective threading. This tap is perfect for light production, fabrication, and maintenance work, and it works well with metals like steel and aluminum.
