The OSG BA Spiral Flute Threading Tap in 8BA is a precision tapping tool designed for blind-hole applications, delivering clean, accurate 8BA threads in tight spaces. Built for small-scale machining and delicate assemblies, it combines durable materials with an advanced coating for reliable, long-lasting performance.

• Size: 8BA threading for compact, fine-thread applications
• Flute Type: Spiral flute geometry for efficient chip evacuation in blind holes
• Material: HSS-E (high-speed steel with cobalt) for greater hardness and heat resistance
• Coating: Steam oxide coating to reduce friction, improve wear resistance, and extend tool life
• Application: Optimized for blind-hole tapping to minimize chip interference and maintain thread quality
• Brand & Technology: OSG threading technology renowned for precision and consistency

The combination of a cobalt-infused substrate and steam-oxide finish delivers robust performance in demanding materials and higher cutting temperatures. The spiral flute aids continuous chip removal, helping you maintain a clean thread and reduce tool binding during deep or restricted-depth tapping. This tap is designed to produce repeatable 8BA threads with tight tolerances, improving assembly reliability in small components, precision housings, and instrumentation enclosures. When you choose this OSG tap, you’re investing in a tool that prioritizes accuracy, longevity, and dependable results for critical machining tasks.
