Description
Designed for machinists who need reliable BSF threading in blind holes, the OSG BSF Spiral Flute Threading Tap delivers precise, durable threads with every use. Built from cobalt-enhanced HSS and finished with a Steam Oxide coating, it’s engineered to withstand tougher materials and high-speed machining while extending tool life.
- Size and Thread: 1-1/4 x 9 BSF (British Standard Fine) threading for accurate fit in blind-hole applications.
- Material: HSS-E (high-speed steel with cobalt) for heightened hardness and heat resistance during demanding cuts.
- Coating: Steam Oxide finish to improve wear resistance and reduce friction at the cutting edge.
- Flute Design: Spiral flutes optimized for efficient chip evacuation in blind holes, helping to prevent clogging and improve surface finish.
- Application: Specifically suited for blind-hole threading tasks in metalworking, fixtures, and precision assemblies.
- Performance: Delivers high-quality, accurate threads with extended tool life under challenging machining conditions.
Whether you’re fabricating a tight-tolerance housing, repairing threaded components, or preparing fastener holes in automotive or industrial assemblies, this tap provides dependable results. The combination of HSS-E material, steam oxide coating, and a spiral flute design translates to cleaner cuts, reduced heat buildup, and longer tool life compared with standard taps, helping you complete critical threading work with confidence and efficiency.
