The Carmex Threading Tap — Spiral Point, UNF Supercut, with Powder Metal construction — is built for machinists who demand precise 1/2-20 UNF threading and durable performance in challenging materials. Designed for speed and reliability, it delivers clean threads with fewer passes.
- Thread type: UNF (Unified National Fine) threading for high-precision, fine-pitched threads.
- Size: 1/2" diameter with 20 TPI (1/2 x 20 UNF).
- Design: Spiral Point (Supercut) geometry that efficiently channels chips forward, reducing clogging and improving cutting action.
- Material: Powder Metal construction for enhanced wear resistance and durability in demanding applications.
- Chip evacuation: Spiral flutes actively move chips away from the cutting edge for smoother, more reliable cuts.
- Application: Ideal for precision threading tasks in metalworking and high-speed tapping scenarios.
The combination of UNF compatibility, spiral point geometry, and powder metal durability helps you achieve accurate thread forms with consistent quality. This tap is a practical, long-lasting choice for shops that tackle fine-thread projects and require dependable performance across a range of materials.
