Learn more about Klarna
The OSG BA Spiral Flute Threading Tap in 3BA is a precision tool built for blind-hole BA threading, designed for machinists who demand reliable, accurate results. Crafted from HSS-E cobalt and finished with a steam oxide coating, it delivers outstanding hardness, heat resistance, and durability in challenging materials.
- Thread Size: 3BA thread, ideal for small, fine BA applications in blind holes.
- Flute Geometry: Spiral flutes optimize chip evacuation and reduce binding during blind-hole tapping.
- Material: HSS‑E (high-speed steel with cobalt) for enhanced hardness and heat tolerance.
- Coating: Steam oxide coating lowers friction and extends tool life under demanding cuts.
- Application: Specifically engineered for reliable threading in blind-hole situations where precision matters.
This tap delivers consistent, high-quality threads with fewer passes, helping to minimize rework and downtime in production tasks. The combination of cobalt-enriched steel and a protective coating supports longer tool life, while the spiral flute design keeps chips moving away from the cutting edge for smoother operation and improved accuracy across multiple threads.
