Frequently Asked Questions


Step bits, auger bits, spade bits, and extra-long flex bits are most commonly used by electricians.

Use a masonry bit that matches the wall plug diameter—typically 6mm to 10mm.

An "electrical bit" refers to a drill bit designed specifically for electrical work, such as wire routing or panel installation.

Auger bits are ideal for drilling long, clean holes through multiple studs without splintering.

Common plug sizes range from 3/4" to 1 1/8"—step bits are ideal for this because they can create multiple hole sizes in one pass.

It depends on the wire gauge and application. For Romex, 3/4" to 1" is typical through studs.

Most electricians use a step bit that covers 3/4" to 1-1/8" sizes for standard conduit fittings. Always check local code and fitting requirements.

A cordless drill and a set of job-specific drill bits are among the most-used tools for electrical installations.

Electricians often use step bits, auger bits, spade bits, and extra long bits. The right bit depends on the material being drilled and the job—metal boxes, wood studs, or finished walls.

A lightweight, high-torque cordless drill with variable speed and compact design is best for electricians.
