UNF Spiral Point Gun Taps are designed for precision machine tapping of Unified National Fine (UNF) internal threads, making them ideal for through-hole applications. The spiral point (gun) design pushes chips forward ahead of the tap, reducing chip build-up, improving cutting efficiency and extending tool life in production environments. Manufactured from high-quality HSS or HSS-E (depending on the product specification), these machine taps are suitable for CNC machining, milling machines, lathes and drill presses. Ideal for threading stainless steel, alloy steel, carbon steel, mild steel and other machinable materials, they provide fast, accurate and reliable thread cutting for engineering, manufacturing, fabrication and maintenance applications.
