Description

Engineered for precision threading in metal through-holes, the OSG Threading Tap delivers reliable M12 x 1.75 threads with exceptional wear resistance. Built from HSS-E with a Steam Oxide Coated Plus finish, it combines durability and heat tolerance to tackle demanding tapping tasks.

  • Thread Type: Metric spiral point threading tap designed for through-hole operations, optimized to form threads efficiently and guide chips forward.
  • Material: HSS‑E (high-speed steel with cobalt) for superior hardness and heat resistance during heavy cutting.
  • Coating: Steam Oxide Coated Plus provides reduced friction, smoother cutting, and extended tool life in demanding environments.
  • Size/Thread: Through-hole compatibility with M12 x 1.75 standard metric threads for reliable fastening compatibility.
  • Geometric Design: Spiral point geometry facilitates positive pressure cutting and effective chip evacuation in through-holes.
  • Application: Ideal for general-purpose tapping in through-holes across a range of metals, with consistent thread quality and repeatable results.

This tap helps you achieve clean, accurately formed threads with fewer reworks. The cobalt-enhanced HSS and Steam Oxide finish work together to resist high cutting temperatures, reducing tool wear during extended production runs. The spiral point design promotes smooth chip evacuation, minimizing the risk of binding and improving cycle efficiency in through-hole applications.
