Of all the automatic hand drills in the market up to the present time there has never been one that has been entirely satisfactory for general use. The trouble has been that no one strength of spring in these tools would be satisfactory in both soft and hard woods, or for the large and small drills furnished with the tool. The best that could be done was to use a spring of av erage strength.

In the new drill, No. 44, manufactured by North Bros. M'fg. Co. Philadelphia, Pa., this difficulty has been overcome by a device to adjust the tension of spring, making it weaker or stronger. The spring is held at desired tension by a small bolt or lock which engages in the cap and is operated by a small knob on side of handle.

To adjust the spring pull down the bolt on side of handle, turn the cap on end of handle to the right for heavier tension for hard wood or larger driils, or to the left for soft woods or smaller drills. Turn cap, to hold it from turning while using the tool.

To open magazine in handle containing the drill points, hold the drill with the chuck end up, and unscrew nut above handle, and all the drill points will be in sight, thus enabling the user to quickly select and remove drill point required. To Insert the drill points, hold the drill with chuck end up, turning sleeve on same to right as far as it will go. Insert drill point so that it catches at the bottom of chuck and will not turn, then turn sleeve to left until drill point is held solid.

The tool is nickel plated and finely finished, the materials and workmanship throughout being of the of the best.
