The OSG UNC Spiral Point Threading Tap is built for precise through-hole threading with speed and reliability. Crafted from HSS-E (high-speed steel with cobalt) and finished with a Steam Oxide coating, it’s designed to deliver durable performance in demanding machining tasks.
- Thread size: 5/8" diameter, 11 TPI UNC, optimized for through-hole tapping.
- Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and heat resistance during cutting.
- Coating: Steam Oxide coating provides improved wear resistance and corrosion protection in challenging environments.
- Geometry: Spiral Point design (gun-tap style) promotes positive chip evacuation and pushes chips ahead of the tool for clean through-hole threads.
- Through-hole suitability: Specifically engineered for through-hole applications, delivering efficient entry, stable cutting, and consistent thread quality.
- Brand precision: OSG’s advanced threading technology ensures accurate thread forms and extended tool life for critical machining tasks.
This tap helps you achieve dependable, high-quality UNC threads with fewer reworks. The combination of cobalt-enhanced HSS-E and a Steam Oxide finish maximizes performance under heat, while the spiral point geometry keeps chips moving forward, reducing clogging in through-holes. Ideal for fabricators and machinists tackling steel and alloy workpieces where precise threading and durability are essential.
