Achieve precise, durable threads in blind holes with the OSG BSW Spiral Flute Threading Tap. Designed for professional machinists and fabricators, it delivers reliable performance in hard metals and everyday production tasks.
- Threading type: BSW (British Standard Whitworth) with a spiral flute for efficient chip evacuation in blind-hole applications.
- Size: 1-1/4" diameter, 7 TPI
- Material: HSS-E (high-speed steel with cobalt) for enhanced heat resistance and extended tool life
- Coating: Steam oxide coating provides wear resistance and reduced friction during cutting
- Flute design: Spiral flutes optimize chip flow, helping prevent clogging in limited-depth holes
- Application: Specifically engineered for blind-hole threading in steel and other tough metals, suitable for production runs and maintenance work
Benefits: The combination of cobalt-infused HSS, steam oxide coating, and a spiral flute geometry means you can expect consistent, accurate threads with longer tool life, smoother entry, and reduced risk of tap breakage in challenging blind-hole jobs. This tap supports reliable performance across demanding machining tasks, from fabrication and repair to maintenance of critical components.
