The OSG BA Spiral Flute Threading Tap is a precision tool designed for blind-hole threading in metalworking. Crafted with HSS-E cobalt and finished with a steam oxide coating, it combines durability with reliable performance for demanding machining tasks.

• Thread size: 1BA—sized for tight, compact blind-hole threads in metal components.
• Flute design: Spiral flute geometry optimized for effective chip removal in blind holes, reducing risk of clogging and breakage.
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and heat resistance under rigorous cutting conditions.
• Coating: Steam oxide finish to improve wear resistance and provide smoother cutting action.
• Application: Specifically engineered for blind-hole threading where accessible flute clearance is limited.
• Durability: Designed to deliver consistent, high-quality threads over longer tool life in demanding environments.

This tapping solution helps machinists achieve precise thread pitches with clean finishes while maintaining longevity in tough metals. Its combination of cobalt-enhanced steel and steam oxide coating ensures stable performance, even when heat and friction rise during deep or challenging blind-hole operations.
