The OSG BSP Spiral Point Threading Tap is a precision through-hole tapping tool built for engineers and machinists who need consistent BSP threads with long tool life. Crafted from cobalt-enhanced HSS (HSS-E) and finished with a robust steam oxide coating, this tap delivers reliable performance in demanding metalworking environments.
- Threading Type: Spiral point geometry designed to push chips forward and promote smooth entry for through-hole BSP threading.
- Size & Pitch: 5/8" diameter with 14 threads per inch (5/8-14 BSP), suitable for common BSP through-hole fits.
- Material: HSS-E (high-speed steel with cobalt) for increased hardness, wear resistance, and heat tolerance during heavy cuts.
- Coating: Steam oxide coating that reduces friction and extends tool life in tough metals.
- Application: Optimized for through-hole tapping to produce precise BSP threads in steel, cast iron, and other common metals.
- Chip Evacuation: Spiral point design aids efficient chip removal, minimizing burrs and improving cycle efficiency.
This tap delivers durable, accurate BSP threads with fewer reworks, helping you complete critical machining tasks with confidence. The combination of HSS-E alloy and steam oxide coating provides reliable performance under heat and wear, while the spiral point geometry keeps chip flow clean in through-hole applications. Ideal for piping, hydraulic, and mechanical assemblies that require dependable 5/8"-14 BSP threads.
