Friction Stir Welding T Series

Tungsten carbide tool

The long-wear, thermal-conductive T Series tool provides a high-quality weld while keeping the metals as cool as possible.

  • Made from solid tungsten carbide
  • Provides higher wear in softer metals (MMCs), higher abrasive aluminums, and magnesium
  • Provides higher thermal conductivity than H13 or MP159 (pulls more heat from the metal)
  • Limited use in steel


Tool is composed of solid tungsten carbide. Available shoulder diameters are 25 mm, 38 mm, 50 mm, and custom. Specify shank size of 1 inch, 25 mm, 38 mm, 50 mm, or custom size. Specify C4 or MM threading. For custom pin sizes, contact MegaStir.
