Power Tools for Electricians

A small set of power tools covers most of what an electrician needs day to day. The bigger decision, before choosing individual tools, is which battery platform to buy into: cordless tools lock you into a battery platform, so electricians usually standardise on one system before buying more tools.

This guide covers the core tools worth owning and what each one is actually for. For hand tools and test equipment, see our electrician tools guide.

The Core Three: Combi, Impact, SDS

Combi Drill

The everyday drill and driver, used for everything from pilot holes to driving screws. For most electricians this is the first cordless tool bought, and it is worth picking your battery platform carefully here, since it is usually the first tool on it.

Impact Driver

Built specifically for driving fixings, an impact driver copes with long screws into joists all day without the wrist strain a standard drill causes when used for the same job.

SDS Plus Drill

For masonry work, chasing, box sinking and drilling through brick, an SDS drill does the job far faster and with far less effort than a standard combi drill would manage.

  • Combi drill: everyday drilling and driving, usually the first tool bought
  • Impact driver: fixings and long screws without wrist strain
  • SDS drill: masonry, chasing and box sinking

Cutting and Holes

Beyond the core three, a handful of accessories and a smaller cutting tool handle the jobs that come up regularly around cable runs and fittings.

  • Hole saws: clean holes for downlights and cable glands
  • Flat wood drill bits: fast holes through joists for cable runs
  • A cordless multi-tool: notching joists, trimming trunking and cutting in awkward spots

Buy accessories to match your platform

Hole saws and drill bits are generally cross-compatible between brands as long as the arbor or fitting matches your drill. Multi-tool blades often are not: check your tool's blade fitting before buying a set.

Starting Out: What Apprentices Need

Apprentices and learners need less than they think when they are starting out. During structured training courses the centre provides tools and equipment, which means you can learn the trade before making any decisions about which cordless platform to invest in.

Once you are working and buying your own kit, the combi drill and impact driver are usually the first purchases, with an SDS drill and the smaller accessories added as the work demands them. For the hand tools and test equipment that come first, see our electrician tools guide.

Frequently Asked Questions

What power tools does an electrician actually need?
A combi drill, an impact driver and, for anyone doing chasing or box sinking, an SDS drill cover the large majority of daily work. Hole saws, flat wood bits and a multi-tool fill in the gaps for cable runs and awkward cuts.
Why does the battery platform matter before I start buying tools?
Cordless tools lock you into a battery platform, so electricians usually standardise on one system before buying more tools. Batteries and chargers are rarely interchangeable between brands, so an early choice saves buying duplicate batteries later.
What is the difference between a combi drill and an impact driver?
A combi drill drills and drives screws, and is usually the first tool bought. An impact driver is built specifically for driving fixings, long screws into joists, for example, without the wrist strain a drill causes over a full day of driving.
Do I need an SDS drill as well?
If your work includes chasing walls, sinking back boxes or drilling through masonry, an SDS drill is worth having. For largely first and second fix domestic work, a combi drill and impact driver may cover most needs on their own.
What tools do I need to start a course?
None, for power tools specifically. During structured training courses the centre provides tools and equipment, so apprentices and learners are not expected to arrive with a van of cordless kit. Your own tools tend to build up once you are working.
