The OSG UNC Spiral Point Threading Tap is designed for precise through-hole threading, delivering efficient cuts and dependable tool life for demanding machining tasks. Crafted with HSS-E cobalt and a durable steam oxide coating, it stands up to heat and wear while producing clean, accurate UNC threads.

• Size and thread type: No. 5 UNC spiral point threading tap for through-hole applications
• Material: High-speed steel with cobalt (HSS-E) for enhanced hardness and heat resistance
• Coating: Steam oxide finish to reduce friction and extend tool life
• Geometry: Spiral point design to efficiently evacuate chips and promote fast, smooth tapping
• Through-hole capability: Optimized for reliable threading in through-hole workpieces
• Length: 40 mm overall length to fit standard through-hole tapping setups

This tap helps you achieve precise, repeatable threads with fewer reworks and less downtime. The combination of HSS-E material and steam oxide coating increases durability under demanding cutting conditions, while the spiral point geometry accelerates chip evacuation for through-hole work. Ideal for production environments and shop floors where consistent thread quality and tool longevity matter, this tap delivers dependable performance from the first cut to the last.
