OSG BSPT Spiral Point Threading Tap in HSS-E with Steam Oxide coating is engineered for precise through-hole BSPT threading. Designed for demanding metalworking tasks, it delivers reliable performance and long tool life for plumbers, machinists, and fabrication shops.
- Thread Size: 1/4" x 19 BSPT (British Standard Pipe Taper) internal thread
- Material: HSS-E (cobalt-enhanced high-speed steel) for improved heat resistance and durability
- Coating: Steam Oxide finish to enhance wear resistance and chip flow
- Geometry: Spiral Point design optimized for efficient chip evacuation in through-hole tapping
- Application: Specifically engineered to create clean BSPT threads in through-holes
- Brand: OSG — trusted for advanced threading technology and precision tooling
This tap combines a robust cobalt-infused core with a protective steam-oxide surface to extend life and maintain consistent thread quality, even in tougher materials. The spiral point geometry helps push chips out of the hole, reducing the risk of binding and rework, making it ideal for through-hole BSPT threading in plumbing, hydraulic, and pneumatic assemblies where reliable, leak-proof connections matter.
