Flexible Shaft Drill Bit are flexible designed for drilling inside walls or around corners. Fish eye holes are provided at each end of the bit, which allows the operator to pull wires from either direction after drilling. An insulated steering guide helps the operator to manipulate the bits within the wall cavity. These invaluable tools can be inserted through small wall openings by the operator to bore holes through studs within the wall cavities without damaging finished walls or ceilings.
