A spiral point tap, also known as a gun tap, is a specialized cutting tool used in machining to create internal threads in a pre-drilled hole. Unlike traditional taps that have straight flutes, a spiral point tap features a unique design with helical flutes that direct the chips forward, away from the cutting area. This innovative design makes it particularly effective for through-hole threading, where the tap can push the chips out of the hole as it advances.The primary advantage of a spiral point tap lies in its ability to handle high-speed threading operations with greater efficiency and reduced risk of chip clogging. By directing the chips forward, the tool minimizes the likelihood of chip buildup, which can cause tool breakage or damage to the workpiece. This makes it an ideal choice for materials that produce long, stringy chips, such as steel, aluminum, and other ductile metals.Spiral point taps are also known for their excellent cutting performance and extended tool life. The helical flutes not only improve chip evacuation but also enhance the cutting action by maintaining consistent contact with the workpiece. This results in smoother, more precise threads and reduces the need for frequent tool changes, ultimately lowering production costs and increasing productivity.Another notable feature of spiral point taps is their ability to perform well in both manual and automated machining environments. In CNC machines, where speed and precision are critical, these taps excel due to their efficient chip removal and reliable cutting performance. Similarly, in manual applications, they provide operators with greater control and reduce the effort required to create clean, accurate threads.When selecting a spiral point tap, it’s essential to consider factors such as the material being threaded, the hole size, and the desired thread quality. Proper lubrication is also crucial to ensure optimal performance and prevent premature wear. With the right setup and maintenance, a spiral point tap can deliver exceptional results, making it a valuable tool in any machinist’s arsenal.In summary, the spiral point tap is a highly efficient and versatile threading tool designed to improve productivity and thread quality. Its forward chip evacuation, robust cutting performance, and adaptability to various machining applications make it a preferred choice for professionals seeking reliable and precise threading solutions. Whether for through-hole threading or working with challenging materials, the spiral point tap stands out as a dependable and effective tool in the machining industry.
