What is SPPT (Spiral Point Tap)?

The SPPT (Spiral Point Tap)—commonly referred to as a Gun Tap—is a high-performance threading tool specifically engineered for through-hole tapping. Featuring a uniquely angled spiral point at the cutting edge, this design pushes chips forward during cutting, resulting in cleaner threads, faster operation, and extended tool life.

Advantages of Spiral Point Taps (SPPT)

Spiral Point Taps are the go-to solution for high-speed, high-precision through-hole tapping. Their forward chip ejection minimizes clogging and lowers the risk of tool failure. These taps excel on materials such as carbon steel, stainless steel, aluminum, and brass. Additionally, they allow for higher cutting speeds and significantly longer tool life compared to standard hand taps. This makes them ideal for CNC machining centers, automated tapping machines, and industrial production environments where performance and consistency are critical.

Limitations of Spiral Point Taps (SPPT)

While SPPT taps are extremely effective in through-hole applications, they are not suitable for blind holes, as forward-moving chips have no space to escape, potentially causing jamming or tool damage. These taps also require adequate chip clearance and may be less efficient when used with brittle materials like cast iron. In such cases, Spiral Flute Taps or coated variants (e.g., TiN-coated taps) are recommended for better chip control and wear resistance.

Summary

In summary, Spiral Point Taps (SPPT) are a smart choice for manufacturers seeking speed, precision, and reliability in through-hole threading applications. Their chip-forward design makes them ideal for use with a wide range of materials and in high-volume, automated machining environments. However, users should select alternative tap types for blind holes or challenging materials. By choosing the right tap for the job, you can maximize productivity and reduce downtime.
