Description

Engineered for machinists who demand precision and durability, the OSG BSW Spiral Point Threading Tap creates accurate 3/16"-24 Whitworth threads in through-hole work. Built from HSS-E (high-speed steel with cobalt) and finished with Steam Oxide, it delivers exceptional wear resistance and heat tolerance for demanding machining tasks.

  • Thread Size: 3/16" x 24 BSW (Whitworth) for through-hole threading
  • Material: HSS-E (high-speed steel with cobalt) for enhanced wear resistance
  • Coating: Steam Oxide finish to improve surface hardness and corrosion resistance
  • Design: Spiral Point geometry to efficiently evacuate chips and streamline through-hole tapping
  • Application: Optimized for reliable, high-quality threads in through-hole components

This tap is designed to deliver consistent thread quality across production runs, reducing tool wear and downtime. The combination of cobalt-enhanced HSS and Steam Oxide coating helps it stand up to tougher materials, while the spiral point enables smoother chip flow, minimizing the risk of built-up material inside the hole. Whether you’re refurbishing components or machining new assemblies, this tap supports precise, durable threads that hold up under use.
