Polygon Shank Style Toolholders & Boring Bars Features & Benefits

  • The Sumitomo polygon shank holders enable an extremely high
    stiffness connection between machine and tool.
  • The conical polygon can take high bending and torque moments
    based on the combination of the face contact to the spindle.
  • This self-guiding coupling system offers high precision and repeatability
  • While using this easy and quick coupling system it is possible
    to gain higher machine utilization time as the set-up and
    tool change times are reduced.
  • The compact design and the high stiffness connection to the
    spindle offer a versatile use on multi-task machines,
    machining centers and turning-milling centers.
  • Monoblock system
  • No additional interfaces
  • Precise positioning; self-guiding with high repeatability
  • High stiffness supported by face contact of holder
  • Carbide shims to prevent holders from damage
  • Simple tool holder change and low-maintenance operation
  • Internal coolant supply directly to the cutting edge
  • Polygon shank and insert seat hardened for long holder life
