Engineered for through-hole precision, the OSG UNC Spiral Point Threading Tap in 1/2-13 UNC delivers durable, reliable threading for demanding metalworking tasks. Its HSS-E construction with a steam oxide finish combines hardness, heat resistance, and long tool life to tackle tough materials with confidence.

• Thread size and design: 1/2-13 UNC through-hole threading tap with spiral point geometry for efficient chip evacuation and clean threads.
• Material: High-speed steel with cobalt (HSS-E) for enhanced hardness and heat tolerance during heavy cutting.
• Coating: Steam oxide coating reduces friction and wear, helping extend tool life in tough drilling and tapping cycles.
• Application: Optimized for through-hole tapping where reliable chip control and precise UNC threads are essential.
• Brand and reliability: OSG engineering delivers consistent performance and durability for critical machining tasks.

This tap is built to deliver consistent, high-quality threads while standing up to repeated use in demanding materials. The spiral point design promotes fast, continuous cutting and efficient chip removal, reducing the likelihood of clogging and rework. With its cobalt-enhanced HSS-E core and steam oxide finish, you can expect improved wear resistance, better heat management, and longer tool life—helping you maintain accuracy and productivity across automotive, hydraulic, and general manufacturing applications where robust UNC threads are required.
