Technical Notes:

  • 15° helix angle provides controlled chip evacuation for softer materials
  • Spiral flute design evacuates chips upward, suitable for blind hole applications
  • HSS-E construction provides heat resistance and durability
  • TiCN coating reduces friction and extends tool life
  • 6HX hexagonal shank for secure tool holding
  • Conforms to DIN dimensional standards
  • Extended size range up to M52 for large diameter threading

Applications:

Optimized for threading operations in softer, more ductile materials including aluminum, copper, brass, and soft steels. Recommended for blind hole threading where controlled chip evacuation is required.
