OSG Threading Tap - UNC Spiral Point HSS-E - Steam Oxide Coated - Through Hole - No. 2 x 56

Engineered for precision threading in through-hole applications, the OSG UNC Spiral Point Threading Tap delivers reliable UNC threads with exceptional durability. Built for machinists and production environments that demand consistent results, this tap combines advanced metallurgy with a practical spiral-point design to optimize every cut.

• No. 2 x 56: UNC-size through-hole tapping tap designed for efficient, accurate threads in through-hole work.
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and heat resistance during demanding cuts.
• Coating: Steam Oxide finish reduces friction, aids heat dissipation, and extends tool life in tough materials.
• Flute Design: Spiral Point geometry promotes forward chip flow, improving evacuation and reducing snagging in through-holes.
• Application: Specifically optimized for through-hole tapping, delivering clean, concentric threads from start to finish.
• Precision Technology: OSG’s advanced threading technology ensures consistent pitch, tight tolerances, and repeatable results.

This combination of cobalt-enhanced steel, durable coating, and an efficient spiral-point geometry means fewer re-cuts and longer tool life, even under high-speed production. The tap handles tougher materials with steady performance, making it a dependable choice for job shops and manufacturing environments that require precise UNC threads in through-holes. Expect smooth operation, reliable thread quality, and reduced downtime across your critical machining tasks.
