The OSG BA Spiral Flute Threading Tap is a precision internal-threading tool designed for 6BA blind-hole applications. It’s crafted for machinists and technicians who demand clean, accurate threads in tight spaces and small-diameter workpieces.
- Thread Size & Type: 6BA British Association internal thread for compact, high-precision assemblies.
- Material: HSS‑E (high-speed steel with cobalt) for enhanced hardness and heat resistance under demanding cutting conditions.
- Coating: Steam Oxide Coated Plus to reduce friction, improve corrosion resistance, and extend tool life.
- Flute Design: Spiral flute geometry for efficient chip evacuation in blind holes, minimizing chip clogging and chatter.
- Application: Optimized for blind-hole threading in metalworking, precision instrumentation, and narrow enclosures where space is limited.
- Precision & Finish: Precisely ground cutting edges and formed threads for consistent thread form and reliable engagement.
With the OSG BA Spiral Flute Threading Tap, you’ll achieve repeatable, accurate internal threads from the first cut. The spiral flute enhances chip removal in blind holes, reducing heat buildup and the risk of cross-threading. The combination of HSS‑E cobalt and Steam Oxide Coated Plus delivers durable performance and steadier results across multiple parts and materials, making this tap a dependable choice for critical machining tasks that demand tight tolerances and clean finishes.
