Description

The OSG BA Spiral Point Threading Tap is a precision threading tool designed for through-hole 7BA applications, delivering clean, accurate BA threads with lasting durability.

  • Threading type: Spiral point design tuned for through-hole tapping, aiding fast, efficient thread formation and smooth chip evacuation.
  • Material: HSS-E (high-speed steel with cobalt) for superior hardness, wear resistance, and heat tolerance in demanding machining environments.
  • Coating: Steam oxide coating to reduce friction, improve surface durability, and extend tool life in repetitive tapping.
  • Size designation: 7BA threading specifically matched for BA-series components and assemblies requiring fine, small-diameter threads.
  • Application: Optimized for through-hole tapping work, providing consistent tapping quality and straight, true threads in precision parts.
  • Brand: OSG, a trusted name in advanced threading solutions known for reliability and consistency.

This tap is engineered to deliver repeatable results in production and repair environments. The spiral point aids forward chip flow, minimizing clogging in through-holes, while the HSS-E composition and steam oxide coating enhance tool life under higher cutting temperatures. Ideal for assemblies in electronics, instrumentation, and small mechanical devices where precise BA threads are essential.
