18V Hammer Drill Kit With 2 Batteries: UK Buying Guide

What does 18V cordless hammer drill actually mean?

The 18V is the nominal voltage of the battery platform - five lithium cells delivering 18V under load. It is not a power rating, it is the system you buy into. Once you own a charger and batteries, every other tool on that platform gets cheaper.

Hammer drill describes a mechanism inside the head. In hammer mode the chuck pulses forward a few millimetres as it spins, hammering a carbide-tipped masonry bit into brick and block while the flutes clear dust. In drill mode the hammer is disengaged and the tool spins only. A combi drill is simply a drill driver that also offers that hammer mode - the selector ring near the chuck switches between modes, and most also offer a screwdriver mode with adjustable clutch.

Cordless just means battery, not mains. For an 18V cordless drill the battery defines runtime as much as the motor does. A 2.0Ah pack holds roughly twice the energy of a 1.5Ah, so it lasts roughly twice as long for the same job, at the cost of a few extra grams on the handle.

Hammer drill vs drill driver - do you need the hammer?

If you never drill masonry, a drill driver is lighter and slightly cheaper and you will never miss the hammer. The moment you need to put a rawl plug into a brick wall, a drill driver fights you. It relies on the cutting edge of the bit alone to scrape brick, which is slow, hot and blunts bits quickly. A hammer drill adds the pounding that lets the carbide tip bite.

For UK homes this is the deciding factor - most walls are brick, block or plaster on masonry. A Bosch UniversalImpact 18V-60 with 2 x 2.0Ah is built around that use case: hammer on for masonry, hammer off for timber and screws. If you only drill into plasterboard and wood, save the money and buy a pure driver, but for any shelf, curtain pole or outdoor fix into brick, hammer is not a luxury.

For dense concrete a SDS rotary hammer is faster, but the 18V combi covers most homes.

Is a kit with 2 batteries worth paying for?

Almost always, yes. The pattern is universal in purchaser reviews: people who buy a single-battery kit love the drill, then complain they had to stop mid-wall to wait for a charge. A second battery turns that pause into a ten-second swap. One charges while the other works, so unless you are drilling dozens of holes back-to-back into concrete, you never stop.

The price gap is modest. On Amazon UK, the jump from 1 x 2.0Ah to 2 x 2.0Ah is typically £30 to £50 and bundles a second battery that costs £35 to £55 on its own. You are effectively getting the spare at a discount plus the convenience. The Makita 18V combi drill with 2 batteries and charger is the classic example - the kit costs little more than the bare tool plus one battery bought separately, and Makita's LXT batteries fit 300-plus tools on the same platform if you expand later.

When a single battery is fine: you do one small job a year, you already own spare batteries on the same platform, or you mostly drive screws rather than hammer drill. In those cases a bare body or 1-battery kit saves cash. For everyone else, the two-battery kit is the one you will wish you had bought when the charger light is still red and the wall is half drilled.

Tip: look at what is actually in the kit. Some listings say 2 batteries but ship one 2.0Ah and one 1.5Ah, or include a slow charger that takes 90 minutes. The sweet spot is 2 x 2.0Ah with a charger that does a full charge in 40 to 60 minutes. The Ryobi R18PD3 ONE+ starter kit is worth a look on value here - ONE+ covers 200-plus tools, so the batteries keep earning after the drill job is done.

Brushless vs brushed - should you pay the premium?

Brushed motors use carbon brushes that rub on the commutator. Brushless replaces them with electronics. The practical difference is that brushless runs cooler, gives 25 to 50 percent more runtime per charge, and tends to last longer because there are no brushes to wear. It also produces slightly more torque for the same battery, which shows when hammer drilling.

Brushless costs about £20 to £40 more. If you drill most weekends that premium pays back quickly. The DeWalt DCD778S2T 18V XR brushless hammer drill is a popular brushless pick in the UK because the XR platform is widely stocked and the bare body is easy to find when you want to add a second tool without another charger.

Which 18V hammer drill kits are worth buying?

You do not need to read every listing - most kits cluster around the same specs. What separates them is battery, charger and how often users actually complain about heat or chuck wobble. Based on purchaser feedback and specifications, these keep coming up well:

Makita 18V Combi Drill with 2 Batteries - the safe default with the widest tool range. Bosch UniversalImpact 18V-60 - compact home-DIY pick for brick. DeWalt DCD778S2T XR Brushless - the upgrade if you want brushless. Ryobi R18PD3 ONE+ - best value if you will add more ONE+ tools.

Whichever you pick, pair it with the right bits. A good drill bit set with carbide-tipped masonry bits for plug sizes 5.5mm and 7mm covers the fixings most UK walls use. Our how to drill into brick guide shows the technique that stops the bit skating and protects the plug.

Bare tool vs kit - the decision in 30 seconds

Buy the kit with 2 batteries and charger if this is your first 18V tool, you drill into brick or block at all, and you do more than one job a year. You get the swap advantage and the spare pays for itself in time alone.

Buy the bare body if you already own batteries on that platform and they are healthy, or you are adding a second drill body to keep a different bit loaded. Do not buy bare to save £40 then spend £50 on a single battery next month.

Buy 1-battery kit only if the discount is steep and you are sure you will not need the continuous running - for example, you own a wired rotary hammer for masonry and the cordless will only drive screws. Otherwise, the second battery is the cheapest upgrade you will buy for the tool.

Frequently Asked Questions

The short version

If your walls are brick or block, buy the 18V combi hammer drill as a kit with 2 x 2.0Ah batteries and a decent charger. You will use hammer mode for masonry and drill mode for everything else, and the spare battery removes the only real drawback of cordless. Pick the platform you want to stay on - Makita LXT, DeWalt XR, Bosch or Ryobi ONE+ - because the next tool gets cheaper once the batteries are in the drawer. For the odd job into concrete, add a set of carbide masonry bits and read how to drill into brick before you start. The hole will be cleaner, the plug will hold, and you will not be hunting for a charger halfway through.

Already own batteries? A bare DeWalt DCD778S2T or Bosch GSB 18V-55 body saves cash. For the full shortlist see best 18V hammer drills.
