| To ensure effective coolant sealing, it is recommended to use a sized shank (shank tolerance: h6). | |||||||||
| The clamping length of the tool shank must be greater than or equal to the bore length of the collet to achieve the coolant-sealing function. | |||||||||
| The diameter of the tool being clamped must not exceed the collet's maximum clamping diameter. | |||||||||
