The spiral flute tap offers excellent thread forming capabilities with its three-flute design and a semi-bottoming finish to provide superior cutting performance. With a UNC (Unified National Coarse) 1/4-20 thread form, it's suitable for industries such as aviation, automotive, military, aerospace, construction, and general machining where precise threads need to be created in metals such as steel, stainless steel, brass, aluminum, or copper. Its 2B & 3B class of fit ensures compatibility with multiple materials, while its SUPER-B finish offers minimal drag during thread cutting, reducing chatter for smooth, clean threads that are ideal for critical applications requiring uniform pitch and form threads. Additionally, its durable construction ensures long-lasting performance, making it an attractive option among industrial users seeking quality tapping tools to meet various material removal requirements.
