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.
