Long twist drill bits for wood.
Carbide tips for long life.

Known as Bell Hanger bits, Installer bits and Low-Voltage bits, these bits are specifically designed for small-diameter wire installation for phone, alarm, video and data systems.

A convenient pull hole lets you retrieve wire from the far side of the wall after drilling through. Carbide-tipped wood bits provide much longer life than bits with standard tips, but should not be used to drill in concrete or brick (use a carbide tip made for masonry).
