What is a Spiral tap?

A spiral tap is a type of tool used for cutting internal threads (female threads) in materials. It features spiral flutes that direct chips upward, which helps to prevent clogging and enables efficient threading in deep or blind holes (holes with a bottom). This design makes it suitable for threading various metals, including steel, stainless steel, and aluminum. Compared to straight-flute taps, spiral taps reduce machining load and the risk of breakage. Additionally, they minimize the chance of chips damaging the threads, making them ideal for applications requiring precision.

Application of Spiral tap

１．Automotive Parts Threading
Spiral taps are commonly used for threading in automotive engine parts and chassis components, where deep and precise threads are required. Their chip-ejection capability ensures a smooth thread finish, reducing the risk of machining defects.
２．Aircraft Component Manufacturing
In aerospace, spiral taps are used for threading hard metals like aluminum and titanium. They are ideal for producing lightweight, high-precision components, as they prevent chips from clogging in blind holes, essential for quality in aviation parts.
３．Precision Electronics Components
Spiral taps are also used in electronics, where precise threads are needed. Blind holes are common in electronic components, so the spiral tap's efficient chip ejection prevents leftover chips that could cause defects.
４．Mold Manufacturing
Spiral taps are used in mold making, where detailed threading is often required. Their smooth chip ejection makes them suitable for deep and complex shapes, ensuring high-quality thread production.

Spiral taps are essential in situations where chip removal is challenging or where high precision is needed.
