OSG BA Spiral Point Threading Tap is a precision tool built to create 5BA through-hole threads with dependable accuracy and extended tool life. Designed for machinists and fabricators working with miniature BA fasteners, it delivers clean, repeatable threads in tight-tolerance parts.

• Threading Tap Type: BA spiral point (gun-tap) design for through-hole tapping, engineered to push chips forward for efficient cutting and reduced clogging.
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness, heat resistance, and wear performance.
• Coating: Steam oxide coating provides lubricity, improved wear resistance, and smoother cutting action.
• Hole Type: Through-hole geometry optimized for reliable tapping in through-hole applications.
• Size/Thread: 5BA thread size, ideal for precise miniature assemblies and specialty hardware.
• Brand: OSG, a trusted name in high-precision threading solutions known for consistency and durability.

When precision matters, this BA spiral point tap delivers consistent, high-quality threads. The spiral point design directs chips out of the hole to minimize interference during cutting, while the cobalt-enhanced HSS-E core maintains sharpness under heat. The steam oxide coating lowers friction and extends tool life, making it well-suited for electronics housings, precision instruments, camera accessories, and other small assemblies that require reliable 5BA threads. For best results, pair with appropriate tapping fluid and a controlled tapping sequence to ensure clean, dimensionally accurate threads every time.
