Learn more about Klarna
Description
The OSG Threading Tap is a metric M1.6 x 0.35 right-hand tap designed for precise threading of blind holes in a variety of metals. Built for machinists and production environments, it delivers reliable performance and long tool life in DIN371 applications.
- Thread format: Metric M1.6 x 0.35, right-hand thread for standard, common-material tapping
- A-Spiral flute: Optimized chip evacuation in deep or blind holes to minimize binding and improve hole quality
- Body material: Powder metal construction for enhanced strength and wear resistance
- Coating: TiCN coating increases hardness and reduces friction, extending tool life in high-speed operations
- Standards: DIN371 compliant geometry to ensure consistent thread profiles and compatibility with standard holes
Designed to deliver consistent thread quality across production runs, this tap excels where blind-hole threading is required. The combination of a powder-metal body and TiCN coating reduces wear under high-speed tapping, while the A-Spiral flute helps keep chips moving even in deeper cavities. Expect dependable performance, smoother tapping, and longer intervals between tool changes across a range of metals.
