Elevate your through-hole tapping with the OSG BSW Spiral Point Threading Tap. Crafted from HSS-E and finished with a durable Steam Oxide coating, this tap is built for precision and long tool life in critical machining tasks—perfect for 1/4-20 BSW threads.
- Thread form: BSW spiral point design that directs chips forward for efficient through-hole threading
- Size: 1/4"-20 (BSW) for standard small-geometry applications
- Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and wear resistance
- Coating: Steam oxide coating to improve heat tolerance, reduce friction, and extend tool life
- Chip evacuation: Spiral point geometry ensures smooth chip removal during tapping
- Application: Specifically optimized for through-hole threading with consistent thread quality
This tap delivers reliable, high-quality threads in demanding environments, helping you reduce cycle times and improve part-to-part consistency. The combination of cobalt-enhanced HSS and a protective steam oxide finish supports prolonged use in hotter cutting conditions, while the spiral point design minimizes chip packing in through-holes. Ideal for precision assemblies, fixtures, and prototypes where accurate 1/4-20 threads are essential.
