The OSG BA Spiral Flute Threading Tap in 7BA is designed for precise tapping of British Association threads in blind holes, delivering reliable, consistent results in tight spaces. Built for professional use, it combines durable powder-metal construction with a wear-resistant TiCN coating to extend tool life and performance.
- Thread Type: BA (British Association) threading in 7BA size with a right-hand thread for standard tapping operations.
- Flute Geometry: Spiral flute design that enables smooth chip evacuation in blind-hole applications, reducing jam risk.
- Material: Powder metal body offering enhanced durability, wear resistance, and heat tolerance for demanding tapping tasks.
- Coating: TiCN (Titanium Carbonitride) coating to lower friction, improve heat resistance, and support higher cutting speeds.
- Application: Specifically engineered for blind holes to produce clean, precise BA threads with dependable form and finish.
- Usage: Ideal for precision machining environments where compact BA threads are required, such as instrumentation, electronics enclosures, and small mechanical assemblies.
With its spiral flute design and TiCN-coated powder-metal body, this tap delivers consistent thread formation, reduces tool wear, and stays cooler under load. The result is steadier production, fewer reworks, and longer intervals between tool changes. This makes it a reliable choice for shops and manufacturers working with delicate or tight-tolerance BA assemblies, ensuring accurate threads and reliable performance in blind-hole tapping scenarios.
