OSG Threading Tap - BSW Spiral Flute HSS-E - Steam Oxide Coated - Blind Hole - 7/16 x 14

The OSG BSW Spiral Flute Threading Tap is engineered for professionals who need precise, durable threads in blind holes. Built from HSS-E cobalt and finished with a Steam Oxide coating, this tap delivers reliable performance for 7/16-14 BSW applications.

• Thread type: BSW spiral flute threading tap designed specifically for blind-hole tapping
• Size: 7/16 x 14 (BSW)
• Material: HSS‑E (high-speed steel with cobalt) for enhanced wear resistance and heat tolerance
• Coating: Steam oxide coating provides corrosion resistance and extended tool life
• Flute design: Spiral flutes optimize chip evacuation in restricted blind holes, reducing plug and breakage risk
• Application: Suited for metalworking, equipment maintenance, and production tapping where blind holes are required
• Performance: Supports accurate thread formation with consistent tolerances and improved tool longevity

With an HSS-E cobalt core and a steam-oxide finish, this tap stands up to demanding metals and high-temperature cutting, delivering stable performance across long runs. The spiral flute design keeps chips moving away from the cutting edge, which means fewer re-threads and cleaner thread finishes in tight blind holes. The result is precise 7/16-14 BSW threads that fit standard fasteners and components, reducing assembly issues and downtime. Built for durability and reliability, this OSG threading tap helps machinists achieve repeatable results and extend tool life in everyday shop tasks.
