A plurality of tool holders support respective different tools and are interchangeable selectively connectable to and detachable from the second end of the end grip member. Each tool holder has a first end to carry a respective tool and a second end having an extension extended into the recess in the second end of the end grip member when such tool holder is connected thereto. The extension is configured to block coolant passage or to allow coolant passage through a selected portion of the coolant line.
