Spiral Hand Drills

This ingeniously simple tool is perfect for drilling small holes in metal or wax models. The adjustable chuck can accommodate drill sizes 57 through 80 (0.34 to 1.09 mm) and the simple design makes it easy to use. Pulling up and down on the knurled plunger causes the body of the hand drill to spin like any other drilling device. The drill is held steady by resting one finger on top. Available with or without a return spring. Overall length is 3-7/8". Constructed of brass with a steel chuck and spring.
