Flexible-Shaft Drill Bits for Wire Installation
 |  |
Round Shank |
Drill inside walls and between floors to install electrical wiring without cutting extra access holes. The shaft on these bits flexes for a long reach in any direction. To install wire, first strip the end and attach it to the small hole at the tip of the bit. Then pull wire back through the drilled hole. Also known as bell hanger bits.
