This spiral flute tap has been constructed with superior vanadium high-speed steel to give optimal performance for heavy-duty tasks such as deep hole drilling or machining tough metals like stainless steel, cast iron, carbon steel among others. The modified bottoming design makes it suitable for drilling smaller holes with accurate bottoming oversize capabilities which prevents breaking off of chips when reaching the end surface without harm to surfaces. Its #12-24 thread size and 3 flutes deliver faster chip evacuation while its 2B class of fit ensures smooth mating when threading pieces together giving consistent high precision fits as per required specifications within industrial applications such as automotive parts manufacture, aviation infrastructure maintenance or hydraulic equipment production to meet quality demands with ease.
