Europa Threading Tap - Spiral Flute - UNF - HSS-E - Green Ring - 1/4 x 28

The Europa Spiral Flute Threading Tap is engineered for engineers and machinists who demand precise UNF threading in demanding metalwork. Crafted from HSS-E with a distinctive green ring for quick identification, this tap delivers reliable cuts and long tool life in tough materials.

• Thread size: 1/4-28 UNF
• Flute style: Spiral flute for efficient chip evacuation and smoother cutting
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and wear resistance
• Shank: Straight cylindrical shank designed for compatibility with standard tapping tools
• Identification: Green ring marks the specialized configuration for quick recognition
• Recommended use: Optimized for UNF threading in steel, stainless steel, and aluminum alloys

When you use this Europa tap, you can expect precise thread formation that meets UNF specifications, reduced chatter, and clean threads that require less finishing. The cobalt-enhanced HSS maintains a sharp cutting edge under higher temperatures, supporting reliable performance during production runs and maintenance work. The spiral flute geometry helps push chips out of the hole, reducing the risk of binding in blind holes and delivering consistent results across parts and batches. The green ring enables quick identification in busy tool cribs, speeding up setup and minimizing mix-ups.
