The OSG Threading Tap Metric Fine A-Spiral Flute is a precision tapping solution designed for blind-hole applications. Built for machinists and engineers who need dependable, accurate threads in tight spaces, it combines durability with smooth, efficient cutting.
- Thread type: Metric fine thread in blind holes (DIN371), right-hand design, sized M4.5 x 0.5 for precise engagements.
- Flute design: A-Spiral flute for efficient chip evacuation and reduced clogging in confined blind-hole environments.
- Material: Powder metal substrate engineered for improved wear resistance and extended tool life in demanding jobs.
- Coating: TiCN (Titanium Carbo-Nitride) coating provides increased hardness, lower friction, and better performance at higher speeds and temperatures.
- Application: Ideal for producing clean, accurate threads in metric blind holes across common metalworking materials.
This combination of material, coating, and flute geometry translates to real-world benefits: longer tool life, more consistent thread profiles, and reliable performance in production runs or on repair jobs. The TiCN coating helps maintain sharp cutting edges, while the spiral flute design minimizes chip buildup, reducing the need for frequent rethreading or cleaning. With this tap, you can achieve precise M4.5 x 0.5 threads in blind holes with confidence and efficiency.
