A positioning device for a drill tool contains a base including a groove to insert and limit the drilling tool; a fixing assembly disposed on the base so that the base is fixed on a workpiece; a pad mounted on a bottom end of the base so that its bottom end abuts against the workpiece tightly and including a receiving chamber mounted therein to correspond to the groove of the base, thereby a cool fluid is fed into the receiving chamber, and the drilling tool inserted in the limiting range is driven to have the drilling process so that during the drilling process, the pad surrounds the drilling tool and the desired drilling position on the workpiece, the receiving chamber is full of cool fluid to cool the drilling tool quickly and to prevent the cool fluid and clips from splash, thus prolonging a service life of the drilling tool. |
