Engineered for precision BSPT threading, the OSG BSPT Spiral Point Threading Tap in 1/2 x 14 through-hole design delivers reliable, high-quality BSPT threads for demanding metalworking tasks.
- Size and thread form: 1/2 x 14 BSPT through-hole threading for accurate, repeatable taps
- Material: HSS‑E (high-speed steel with cobalt) for superior wear resistance and heat tolerance
- Coating: Steam Oxide coating reduces friction and enhances tool life in tough cutting conditions
- Geometry: Spiral Point design facilitates efficient chip evacuation and smooth thread formation
- Through-hole design: Optimized for through-hole tapping to improve alignment and reduce clogging during operation
This tap is ideal for through-hole BSPT applications across metals such as steel and cast iron, offering precise threads with extended tool life. The combination of cobalt-infused HSS-E and a durable steam oxide coating helps maintain cutting performance under higher heat, while the spiral point geometry minimizes chip buildup and improves tapping speed. For reliable, repeatable BSPT threads in fittings, housings, and other components, this OSG tap delivers consistent results with reduced downtime.
