The OSG UNC A-Spiral Point Threading Tap is a precision tool engineered for through-hole UNC threading. It’s ideal for machine shops and professionals who demand dependable performance, clean finishes, and long tool life.

• Thread type: UNC A-spiral point design for efficient chip evacuation and clean, fast through-hole threading.
• Size: 1-8 UNC (1-inch diameter, 8 TPI) for standard Unified National Coarse applications.
• Material: Powder metal construction delivers durability and toughness under high-speed cutting.
• Coating: TiCN coating enhances heat resistance and wear performance for extended tool life.
• Orientation: Right-hand threading aligned with common metalworking practices and tooling setups.
• Through-hole compatibility: Optimized for through-hole tapping and DIN2184-1 specification to ensure reliable thread quality.
• Chip control: Spiral point geometry promotes forward chip flow, reducing clogging and allowing higher cutting speeds.

Using this tap yields consistent thread accuracy and a smoother finish across a variety of materials, including steel, aluminum, and other common metals. The TiCN coating helps resist heat buildup during demanding operations, while the powder metal core provides resilience against wear and deformation. The combination supports higher productivity in production runs, maintenance tasks, and precision assemblies that rely on robust UNC threads with reliable engagement.
