Precision-engineered threading tap designed for UNF through-hole applications, the OSG UNF A-Spiral Point Tap delivers reliable, high-performance threading for through holes. Built with a powder-metal body and TiCN coating, it’s crafted for durability and consistent results in demanding machining environments.

• UNF A-Spiral Point geometry: Efficient chip evacuation and smooth thread formation in through-holes.
• Material: Powder-metal construction for exceptional wear resistance and heat tolerance.
• Coating: TiCN coating reduces friction, extends tool life, and improves cutting performance.
• Right-hand thread: Specifically designed for standard UNF right-hand threading.
• Through-hole DIN2184-1: Meets DIN2184-1 specifications for reliable through-hole tapping.
• Size: 1/2 x 13 (UNF) suitable for common precision applications.

This tap enables clean, precise UNF threads with minimal resistance and consistent results across a range of materials. The spiral point design promotes smooth chip flow, reducing heat buildup and the chance of tap binding. With the durability of powder metal and the low-friction benefits of TiCN, you can expect longer tool life, fewer insert changes, and repeatable thread quality, even in high-speed or high-feed operations. Ideal for aerospace, automotive, and general precision manufacturing tasks that demand accurate through-hole threads and reliable performance.
