The OSG Threading Tap UNF A-Spiral Point is a precision through-hole tap engineered for high-strength UNF threads. Designed for machinists and manufacturers who demand consistent, accurate results, this tool blends durable powder metal construction with a TiCN coating to extend life and performance.

• Thread form: UNF (Unified National Fine) taps for fine-pitch threading in through-holes.
• A-Spiral Point geometry: Provides efficient chip evacuation and clean, ahead-of-thread fastening in through-hole applications.
• Substrate: Powder metal formulation delivers enhanced durability, wear resistance, and heat tolerance in demanding machining conditions.
• Coating: TiCN coating reduces friction, lowers cutting temperature, and extends tool life for repetitive use.
• Cut direction: Right-hand threading—standard orientation for common through-hole tapping jobs.
• Through-hole design: Optimized for through-hole work, enabling reliable, consistent thread formation from start to finish.
• DIN2184-1 compliance: Built to DIN2184-1 specifications to ensure proper fit and performance with compatible tooling and components.
• Size: No.5 x 40, providing a compact tap suitable for smaller through-holes with precise thread depth.

This tap is purpose-built for through-hole UNF threading across a range of materials, delivering a clean, accurate thread with minimal walk-off. The spiral point helps push chips ahead of the cutting edge, reducing tool chatter and improving cycle times in production environments. The TiCN coating work synergistically with the powder-metal substrate to resist wear and maintain sharpness, enabling more holes per tool and reducing downtime for tool changes. Ideal for shops focused on automotive components, electronics housings, and precision mechanical assemblies where small, high-fidelity UNF threads are critical.
