Achieve clean, precise BSPT internal threads with the OSG BSPT Spiral Point Threading Tap. Designed for through-hole tapping in metalworking environments, it combines high-speed steel with cobalt (HSS-E) and a durable Steam Oxide finish for reliable, long-lasting performance.

• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and wear resistance.
• Coating: Steam Oxide coating to improve heat tolerance and surface durability.
• Thread type: BSPT (British Standard Pipe Taper) threading for accurate tapered internal threads.
• Tip/geometry: Spiral Point design supports efficient chip evacuation in through-hole tapping.
• Through-hole design: Specifically optimized for tapping through-hole environments to maintain thread quality.
• Size: 3/8 in. diameter x 19 TPI (BSPT) for precise, compatible threading.

This tap delivers repeatable, high-quality BSPT threads essential for plumbing, hydraulic, and pneumatic assemblies, as well as other applications requiring reliable through-hole threading. The combination of HSS-E with Steam Oxide coating minimizes wear, extends tool life, and helps maintain consistent thread profiles across multiple holes. Use with appropriate lubrication and steady feed to maximize performance and achieve consistent fit with BSP fittings.
