Combi Drill vs Impact Driver: What's the Difference?

By the Cordless Tool Bench editorial team · Updated 2026 · How we test & score

Combi drills and impact drivers look similar but do different jobs, and many tool owners end up with both. This guide explains what each is for, how they differ, and which to buy first.

Quick verdict

Buy a combi drill first - it drills wood, metal and masonry and drives screws, so it is the versatile all-rounder. Add an impact driver when you drive a lot of screws or long fixings, since it does that faster and with far less wrist strain. They complement each other, which is why twin packs of the two are such popular value.

What a combi drill does

A combi drill is the versatile primary tool: it drills into wood and metal, hammer-drills into masonry, and drives screws via an adjustable clutch. Its keyed or keyless chuck takes round and hex bits and a wide range of drill bits. If you could only own one, this is it, because it covers the broadest range of drilling and driving jobs.

What an impact driver does

An impact driver is a specialist for driving screws and bolts. It uses rapid rotational impacts to deliver high turning force in short bursts, driving long screws into hardwood and decking with ease and almost no wrist strain. It takes hex bits only and is more compact than a combi, but it does not have a clutch or hammer mode for drilling masonry.

Key differences

Which to buy first

Start with the combi drill for its all-round ability. If you find yourself driving lots of screws, building decking, fixing plasterboard or assembling a lot, add an impact driver and you will wonder how you managed without it. For many people the ideal is a twin pack, getting both at better value than buying separately.

Frequently asked questions

What is the difference between a combi drill and an impact driver?

A combi drill is the versatile all-rounder that drills wood, metal and masonry and drives screws. An impact driver is a specialist that drives screws and bolts fast with high force and little wrist strain, but does not drill masonry.

Should I buy a combi drill or impact driver first?

Buy the combi drill first - it is the versatile primary tool for drilling and driving. Add an impact driver when you regularly drive long screws or build decking, where it is far easier on the wrist.

Do I need both a drill and an impact driver?

Not essential, but many find the pair ideal: the combi for drilling and masonry, the impact driver for fast, effortless screw-driving. Twin packs make owning both good value if you do a lot of driving.
