Description

Engineered for precision BA threads in blind holes, the OSG BA Spiral Flute Threading Tap (2BA) delivers clean, accurate threads in tight spaces. Designed for toolmakers, machinists, and electronics enclosures that demand reliable, high-quality threading, it combines durability with dependable chip clearance for demanding small-scale tasks.

  • Thread size: BA 2 (British Association) for fine, compact threads used in small components.
  • Material: HSS-E (high-speed steel with cobalt) for higher hardness and heat resistance.
  • Coating: Steam oxide coating reduces friction and enhances wear life in repetitive cuts.
  • Flute design: Spiral flute geometry optimized for efficient chip evacuation in blind holes.
  • Application: Specifically intended for blind-hole threading, delivering reliable performance in tight cavities.
  • Brand: OSG threading taps — trusted engineering for precision threading.

With a cobalt-enriched HSS-E core and steam-oxide finish, this tap sustains sharpness and resists heat during deeper, fine-thread cuts. The spiral flute design moves chips efficiently out of the hole, lowering the risk of binding and reducing wear on the tool—particularly important when threading small blind holes where chip control matters. The result is consistent, high-quality BA threads that improve assembly reliability in electronics housings, precision instruments, and other compact mechanical assemblies. For professionals and serious hobbyists alike, it minimizes rework and downtime while delivering dependable performance across multiple workpieces.
