Description
The HL-777 Guide assists installers in steering through complex wall structures.
Its insulated guiding feature helps the bit maintain direction even when navigating blind inside a wall cavity.
Ideal for electricians working in finished homes, commercial spaces, and renovation environments.

Unique flexible self feeding bits up to 72” long suitable for drilling holes down the length of wall cavities and through hidden studs with no damage to wall board, plaster or any exterior finish.

A self-feeding screw point and an insulated steering guide helps the operator to start and steer the bit while it is hidden inside the wall cavity.

This bit has a hole at the tip and the shank, which allows you to fish wire inside the wall cavity from either direction after drilling.
