Description
The OSG Metric A-Spiral Flute Threading Tap is a precision tool designed for blind-hole tapping in metalworking. Ideal for professional machinists and machining shops, it delivers consistent, tight threads with enhanced wear life.
- Size: M4 x 0.7 (DIN371)
- Material: Powder metal for toughness and durability
- Coating: TiCN coating to increase surface hardness and reduce friction
- Flute Design: A-Spiral flute for efficient chip evacuation and reduced clogging
- Tolerance: 7GX for an extra-tight thread fit
- Direction: Right-hand threading
- Application: Optimized for blind-hole threading in metallic components
This combination of a high-precision 7GX tolerance, TiCN-coated surface, and spiral flute design translates to cleaner threads, longer tool life, and more reliable performance in challenging drilling depths. The powder-metal composition provides a balanced blend of hardness and toughness, making it a dependable choice for automotive, aerospace, and general manufacturing environments where precise blind-hole threads matter.
