OSG Threading Tap - UNF Spiral Flute HSS-E - Steam Oxide Coated - Blind Hole - No. 10 x 32

The OSG UNF Spiral Flute Threading Tap is a precision cutting tool designed for blind-hole work, delivering accurate threads with reliable durability. Built for machinists who demand consistency and long tool life, this tap combines advanced materials and coatings to perform in demanding metals.

• Thread Type: UNF (Unified National Fine) spiral flute threading for precise, tight-tolerance threads in blind holes.
• Size: No. 10 x 32, matching standard UNF specifications for fine-thread applications.
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and heat resistance under heavy cutting.
• Coating: Steam oxide coating to reduce friction, improve wear resistance, and extend tool life in challenging materials.
• Flute Design: Spiral flute geometry optimizes chip evacuation, minimizing binding and reducing the risk of tool breakage in deep or blind holes.
• Applications: Ideal for high-precision blind-hole threading in metal projects, fixtures, and assemblies where access is limited from one end.

This tap supports clean, accurate threads and enduring performance across tough machining tasks. The combination of HSS-E cobalt composition and steam-oxide finish helps maintain edge retention and resistance to heat buildup, while the spiral flute design enhances chip clearance for smoother operation. Use with appropriate cutting fluid and steady feeds to maximize life and thread quality in production, repair, and fabrication environments.
