OSG BSPT Spiral Point Threading Tap is a precision tool designed for through-hole BSPT threading tasks, built for professionals who demand consistent, high-quality results and long tool life.

• Thread Type: BSPT (British Standard Pipe Taper) threading for accurate pipe fittings and related components.
• Material: HSS‑E (high-speed steel with cobalt) for enhanced heat resistance and extended edge life under demanding cutting conditions.
• Coating: Steam Oxide finish reduces wear and helps dissipate heat during heavy tapping.
• Flute Design: Spiral Point geometry optimizes chip evacuation, keeping the work surface clear and reducing tapping torque in through-hole operations.
• Through-Hole Capability: Specifically optimized for through-hole tapping to deliver consistent, clean threads along the entire work length.
• Shank/Drive: Square drive shank provides secure, positive engagement with tapping fixtures for precise alignment and repeatable starts.
• Size: 1 x 11, the stated dimensions aligned with standard through-hole BSPT threading tasks.

This tap delivers reliable BSPT threads with reduced tool wear and fewer rework instances. The combination of HSS‑E and steam oxide coating supports durability and heat resistance, while the spiral point design maintains steady chip flow for smoother, faster tapping. Ideal for critical machining tasks in production environments where thread integrity matters.
