The Europa Spiral Point UNF threading tap (7/16 x 20) is built for precision through-hole threading in demanding metalworking environments. Crafted from high-speed steel with cobalt (HSS-E) and identified by a distinctive yellow ring, it combines durability with quick recognition in busy workshops.

• Size: 7/16" diameter, 20 UNF
• Configuration: Spiral Point (gun-style) geometry for efficient chip evacuation in through-holes
• Material: High-Speed Steel with cobalt additives (HSS-E) for enhanced hardness and heat resistance
• Identification: Yellow ring marks the specialized spiral-point configuration for fast recognition
• Application: Suitable for through-hole tapping in common metals, including steel, stainless steel, and aluminum
• Use case: Ideal for production runs, maintenance, and engineering projects that require reliable, repeatable threads

The tap is designed to deliver consistent, accurately formed UNF threads with fewer passes and smoother chip evacuation. Its spiral-point geometry pushes chips forward, reducing the risk of clogging in through-holes and facilitating quicker tool changes in high-volume environments. The cobalt-enhanced HSS ensures better wear resistance and performance under higher cutting temperatures, extending tool life when tapping tougher materials. The visible yellow ring helps operators identify the tool’s specialized configuration at a glance, speeding up setup and reducing setup errors. This makes the Europa tap a dependable choice for engineers and machinists aiming for efficient, quality threading in everyday manufacturing tasks.
