Achieve precise, durable threading with the OSG UNC Spiral Flute Threading Tap. Designed for blind-hole applications, this tap delivers clean, accurate 9/16"-12 UNC threads with extended tool life thanks to advanced materials and coatings.

• Tap Type: Spiral flute design optimized for efficient chip evacuation in blind holes, reducing clogging and improving thread consistency.
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and wear resistance under demanding cutting conditions.
• Coating: Steam oxide coating lowers friction and improves heat resistance to extend tool life during through- and blind-hole threading.
• Size & Thread: 9/16" diameter with 12 threads per inch (UNC), matching a standard coarse-thread specification for robust assemblies.
• Application: Ideal for professional machining tasks where precise internal threads are required in blind holes, supporting dependable performance across common metalworking materials.

OSG’s threading technology delivers high-quality, accurate threads with improved longevity, helping you tackle critical machining tasks with confidence. For best results, use with a compatible tap wrench and appropriate cutting fluid to maintain thread accuracy and maximize tool life across multiple holes.
