Learn more about Klarna
Description
The Carmex Spiral Flute Metric Supercut Threading Tap is a precision tapping tool built for metric threading in tough materials. Designed for professionals and serious hobbyists, it delivers reliable, clean threads with consistent performance in demanding machining setups.
- Thread Size: M12 x 1.25
- Flute Design: Spiral flutes for efficient chip evacuation and reduced clogging
- Material: Powder Metal body with HSS-E cutting edges for durability and heat resistance
- Cutting Edges: HSS-E (high-speed steel with cobalt) for enhanced performance under high-speed threading
- Applications: Optimized for metric threading in tough materials and high-speed tapping operations
This tap helps you achieve precise thread forms with less tool wear, thanks to its spiral flute geometry that keeps chips moving away from the cutting edge. The combination of powder metal construction and HSS-E cutting edges means better wear resistance and heat tolerance, enabling reliable performance across steel, cast iron, and other demanding metals. Whether you’re setting threads for fasteners or creating threaded holes in welded assemblies, this tap supports fast, accurate threading with minimal rework.
