The OSG BA Spiral Flute Threading Tap in 10BA is a precision threading tool designed for blind-hole applications. Built for machinists and precision instrument makers, it delivers clean, accurate threads with extended tool life.

• Size and Thread Type: 10BA British Association thread designed specifically for precision blind-hole threading
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and heat resistance
• Coating: Steam oxide coating to improve wear resistance and lubricity during cutting
• Flute Design: Spiral flute geometry optimizes chip evacuation in confined blind holes, reducing clogging and breakage
• Application: Ideal for producing accurate internal threads in small-diameter, restricted-depth holes
• Brand/Technology: OSG threading technology focused on delivering precise, consistent threads and longer tool life

This tap couples a tough cobalt-enhanced core with a specialty spiral flute to handle challenging blind-hole work. The combination minimizes heat buildup and wear while ensuring you achieve reliable thread engagement on every part. It’s well-suited for precision assemblies in instrumentation, small enclosures, and other applications where space is limited and thread quality matters.
