The OSG Threading Tap, Metric A-Spiral Flute, is a high-performance right-hand tap designed for precise threading of blind holes in a range of materials. Ideal for engineers and machinists, it combines durability with efficient chip evacuation to deliver consistent results in demanding production environments.
- Thread Type: Metric A-Spiral flute optimized for quick chip evacuation in blind holes
- Size & Standard: M4 x 0.7 with DIN 376 specification for reliable compatibility
- Material: Powder metal substrate delivering robust strength and wear resistance
- Coating: TiCN coating to increase hardness, reduce friction, and extend tool life
- Orientation: Right-hand threading suitable for common internal threading tasks
- Application: Specifically engineered for tapping blind holes, supporting deep hole accuracy and smooth operation
With the combination of a tough powder-metal core and a hard TiCN coating, this tap maintains sharpness longer, reduces heat buildup, and minimizes insert wear during high-speed production. The A-flute geometry improves chip clearance in deep or restrictive holes, helping to prevent chip packing and improve thread quality. DIN 376 compatibility ensures dependable performance across standard tapping applications, making this tool a reliable choice for shops that demand consistent, repeatable results.
