Structural Steel T-A®    360 Icon
T-A® structural steel drilling system is designed for use on structural steel materials. This system delivers outstanding performance and durability.
Advantages
  • TiAlN and AM200® insert coatings increase tool life in MQL applications
  • Multiple geometries available
  • Holders are compatible with GEN2 T-A® inserts for increased performance
Features
  • 150º structural steel geometry for reduced exit burr
  • NotchPoint® geometry for improved hole straightness
  • Thin Wall geometry for materials under 7/16" (11 mm) thick
  • Morse taper shanks with through-shank coolant capability
  • Various tool lengths to accommodate different reaches
