The HYDRO-GRIP type G3 has a very compact design. It comes equipped with a built in safety device to prevent the tool from falling out when the chuck is not pressurized. This holder utilizes an Allen wrench for operation. These chucks allow for easy tool changes, while keeping perfect run-out and repeatability.
