Description
The OSG UNC A-Spiral Point threading tap is a precision tool designed for through-hole threading in Unified National Coarse (UNC) applications. Built for professional metalworking, it combines durable powder metal construction with a TiCN coating to deliver reliable, long-lasting performance.
- Thread type: UNC A (Unified National Coarse) for standard, widely compatible through-hole threads.
- A-Spiral Point geometry: Optimized for efficient chip evacuation and fast, clean thread formation in through-holes.
- Material: Powder metal body offering enhanced wear resistance and durability under demanding tapping conditions.
- Coating: TiCN coating boosts heat resistance and tool life, maintaining thread quality at higher speeds.
- Through-hole compatibility: Specifically engineered for through-hole DIN2184-1 applications, ensuring reliable fitment and performance.
- Size and length: No.5 x 40, a compact, versatile size suitable for common through-hole threading tasks.
- Tool orientation: Right-hand cut, ideal for standard clockwise threading operations.
This tap is built to help machinists achieve faster cycle times and consistent thread quality on a variety of materials. The spiral-point design pushes chips forward, reducing clogging and improving feed stability, while the TiCN coating and powder-metal construction work together to extend tool life and maintain a smooth finish across multiple taps. Ideal for automotive, general manufacturing, and repair work where dependable UNC through-hole threads per DIN2184-1 are required.
