LSDI LS-62-348 1/2” ReBore-Zit 3/8” Pilot Size

The LSDI LS-62-348 is a 1/2 inch ReBore-Zit drill bit with a 3/8 inch pilot size. It is specifically made to enlarge an existing hole without disturbing any wire inside. The bit features a hollow body with a free-spinning, swivel eyelet mounted on the pilot shaft.

Simply secure the bit into your drill and enlarge the hole to the desired size without twisting or damaging the wire inside. Use this tool to step up from the preexisting pilot hole size in controlled increments until the final size is reached.
