<p>The tool has the shaft (2) and the clamping pin (3), and radially shrinkable feed (5) and chuck (4) to prevent the leakage of the cooling liquid. The cutting tool, feed, and chuck are freely combined, for the flow of the cooling liquid. A cavity (10) is provided with respect to cylindrical shrinkable chuck as several continuous closed grooves, such that the length is greater than the length extending between the clamping pin (3) of cutting tool and extending contact surface (6) of chuck.</p> |
