Achieve precise, durable threading with the OSG BSW Spiral Flute Threading Tap. Built for blind-hole work, this high-performance tap combines advanced metallurgy with a proven flute design to deliver accurate threads and longer tool life for demanding metalworking tasks.
- Thread type: BSW (British Standard Whitworth) spiral flute threading tap optimized for blind holes
- Material: HSS‑E (high‑speed steel with cobalt) for exceptional hardness and heat resistance
- Coating: Steam oxide coating enhances wear resistance and longevity in tough cutting environments
- Flute design: Spiral flutes promote efficient chip evacuation and smoother cutting in confined blind-hole passages
- Size: 5/8 in major diameter with 11 threads per inch (5/8 x 11 BSW)
- Application: Specifically suited to blind-hole threading where reliable chip clearance and consistent thread form matter
With its cobalt-enhanced HSS and durable steam-oxide finish, this tap maintains cutting performance under heat and friction, reducing the risk of galling and extending service life. The spiral flute geometry helps move chips out of deep pockets, minimizing binding and re-cutting errors in hard metals or serialized components. Ideal for shop floors and production environments that require precise, repeatable BSW threads in blind holes without frequent tool changes.
