Engineered for precision threading in through-hole applications, the OSG BSW Spiral Point Threading Tap delivers reliable, high-quality imperial threads. Crafted from HSS-E cobalt and finished with a Steam Oxide coating, it’s built for demanding machining tasks and extended tool life.
- Thread Type: BSW (British Standard Whitworth) spiral point design optimized for through-hole tapping
- Material: High-Speed Steel with cobalt (HSS-E) for enhanced hardness and heat resistance
- Coating: Steam Oxide coating to reduce friction and extend tool life
- Geometry: Spiral Point geometry promotes efficient chip evacuation and straight-thread formation
- Application: Ideal for creating internal threads in through-hole workpieces
- Size: 1-1/4 x 7 (BSW)
This tap is designed to deliver clean, accurate threads with fewer passes, helping you minimize rework and maximize productivity. The combination of HSS-E material and steam oxide coating provides durable performance under higher cutting temperatures typical of through-hole tapping, while the spiral point pushes chips forward rather than back into the hole. Perfect for shops and jobs requiring reliable imperial threads in steel, cast iron, and similar materials.
