The OSG BA Spiral Point Threading Tap in 11BA size is a precision tool built for BA-sized through-holes. Crafted from cobalt-enhanced HSS-E and finished with a steam oxide coating, it delivers durable, accurate threads in tight spaces for electronics, instrumentation, and other small-precision applications.

• Thread Size and Type: 11BA BA-thread spiral-point tap designed specifically for through-hole threading.
• Material: HSS‑E (high-speed steel with cobalt) for enhanced hardness and heat resistance.
• Coating: Steam oxide finish reduces friction and improves wear resistance during tapping.
• Design: Spiral-point geometry promotes efficient chip evacuation, minimizing clogging in through-holes.
• Applications: Ideal for BA-thread through-holes in electronics, instrumentation, and precision machinery.
• Durability: Precision grinding and robust construction extend tool life in repetitive tapping tasks.

With its cobalt-enhanced HSS-E core, steam-oxide coating, and spiral-point design, this tap delivers consistently clean, accurate BA threads while resisting heat and wear. The spiral-point geometry pushes chips toward the exit, reducing the risk of clogging and improving cycle times in production. Suitable for through-hole BA threading, it supports reliable assemblies, minimizes rework, and lowers downtime by providing long-lasting performance in your BA-thread projects.
