The Micro Drill System hand piece accommodates a 3/32" shaft size (0.093").

Unlike most hand-held tools, the Micro Drill has a tiny, high speed DC motor in the hand piece, eliminating cumbersome drive cables and giving you better control. A separate power supply keeps the hand piece lightweight and reduces operator fatigue. The Micro Drill features high quality construction for doing delicate work and the quick change chuck makes for easy bit replacement. Base unit has controls for forward/reverse and speed up to 45,000 RPM. See larger image of Micro Drill System.
