Precision threading for 14BA through-hole work, the OSG BA Spiral Point Threading Tap is built for machinists who demand accurate, durable threads with long tool life.

• Thread Size & Form: 14BA British Association thread with spiral point geometry to push chips ahead and promote clean, accurate thread formation in through-hole applications.
• Material & Coating: HSS‑E (high‑speed steel with cobalt) plus a steam oxide coating for enhanced hardness, heat resistance, and reduced friction during cutting.
• Through-Hole Design: Specifically optimized for through-hole tapping, delivering reliable exits and consistent thread quality from entry to finish.
• Durability & Consistency: Cobalt-enriched base and protective coating extend tool life under demanding speeds and materials, helping maintain precision over more holes.

This tap pairs a robust HSS‑E core with a coating that minimizes wear and temperatures, making it a dependable choice for small-diameter BA threads in electronics housings, instrument casings, and other precision components. The spiral point ensures efficient chip evacuation, reducing the risk of chip packing and chatter so you achieve reproducible thread quality each cycle. Built for repeatable results, it’s a smart investment for shops seeking reliable, long-lasting threading performance.
