Unlike traditional wire-installing drill bits, you do not need to strip the end of the wire when using one of these bits. After drilling, insert the wire into the bit's hollow shaft and pull through the hole.

Flexible-Shaft Drill Bits
for Wire Installation

The shaft is made of spring steel instead of hardened steel, so it flexes while drilling, allowing you to drill inside walls or between floors.
