Challenge: To find the best possible tool-holder system for your needs.

Solution: Get verified test data from an independent survey.

The well-reputed RWTH Aachen University in Germany has recently carried out a new study on Coromant Capto and comparable holding systems. The test series conducted by the university’s machine tool laboratory (WZL) in 2009 compared bending stiffness and torque resistance of Coromant Capto with comparable sizes of other standardized tool-holder systems.

The results were striking: None of the competing tool-holding systems could achieve even close to the same results as the Coromant Capto coupling.

“This is yet another proof that Coromant Capto is the best option for standardization across all machines in the workshop,” says Ronald Schreiber, manager for Coromant Capto at Sandvik Coromant.

Among other things, the study showed that the greater wall thickness of Coromant Capto in comparison to HSK allows for higher clamping forces. These higher clamping forces translate into increased bending stiffness .

Independent comparative data on tooling systems are difficult to come by.
