For people who do the work themselves

You are not buying a tool. You are picking a side for ten years.

The drill is the easy part. The day you want the saw that goes with it, the battery decides, not you. We explain what fits what, what changing your mind actually costs, and which tool does the job in front of you. We also score jobsite machines on their published figures: 6 comparisons, and 6 jobs explained step by step.

By job

Laying a concrete slab

Dig out, compact, form up, reinforce, pour, level, cure: seven steps and the machines that are better hired.

Building a metal stud partition

Set out, fix the frame, run the cables, screw the boards, tape and joint: six steps and the kit that goes with them.

Tiling a floor

Base, setting out, adhesive, laying, cuts, grout: six steps, and the right tool for every cut.

Read more

Laying a floor screed, liquid or sand and cement

Prepare the base, isolate the edges, set the level, pour and dry: both methods and the kit each one needs.

Read more

Insulating a loft, cold or converted

Read the loft, fix what hides under the insulation, protect flue and downlights, insulate without compressing: both cases and the kit each one needs.

Building a timber deck

Prepare the ground, set the supports, fix the joists, screw the boards, finish the edges: the steps of a deck that stays put.

Calculators

Quantities before you buy: bags, boards, tiles. Each calculator shows its formula and says what it does not replace.

Concrete and mortar

How many bags of cement for your slab, assumptions included.

Tiles and adhesive

Tiles, bags of adhesive, grout and spacers, by tile format.

Plasterboard partition

Boards, track, studs, screws, tape and compound, centres included.

Timber decking

Boards, joists and screws, from joist spacing and board width.

Loft insulation

Bags of blown wool or rolls for a slope, from the pack size you enter.

The decision that locks you in

Your battery platform

9

platforms compared, with the maker's own figures

Switching platform costs you every battery you already own. It is the most expensive decision in your tool collection, and the one most people make without thinking.

Pick a platform

The gap nobody fills

Battery adapters

12

adapters verified in the right direction

Running a Makita tool off a Parkside battery is possible, it is sold, and it carries real risk. We say which adapter exists, in which direction, and when not to use one.

One battery, many brands

The three alliances

3

brand alliances, incompatible with each other

AMPShare, CAS and Power for All run tools from dozens of makers off a single battery. It is the least known fact in the category, and it changes the maths.

How alliances work

What people actually type

If you take one thing from this site: choose the battery platform before you choose the tool. An impact driver can be replaced; a platform is something you live with. Once you own three batteries from one maker, the cost of leaving is almost always larger than the price gap that would have changed your mind.

What this actually looks like

Three situations these machines really meet. The photographs come from the makers: we do not stage jobsites we have not worked on.

Drilling a concrete wall with the DeWalt DCH273 and dust extraction
Drilling concrete, for a whileFixing a rail, a bracket, a guardrail. This is where impact energy earns its keep and where dust becomes a real subject.
Drilling an interior wall with the Ryobi R18SDS
Drilling an interior wallA shelf, a wall unit, a radiator. An entry level machine is enough, as long as you know what sits behind the board.
Drilling into tile with the Metabo KH 18 LTX BL 24
Drilling tile without cracking itThe case where hammer rate matters more than force. Rotation only through the glaze, then hammer once you are through.

Where to start

Starting from nothing

No cordless tools yet, a job coming up. The decision guide starts from how you actually work, not from a ranking.

Pick your first platform

I already own batteries

The question is no longer which brand, but what your platform can do and what it will never do.

See all nine platforms

18V or 20V MAX

The same battery carries two different numbers depending on the market. It is the first confusion in the category, and it is deliberate.

Understand the difference

How many bags

Concrete, mortar, quantities. The assumptions behind the number are written down, not hidden behind a result.

What this site does not do

We do not bench test tools, and we do not pretend to. What we do is documentary: read what manufacturers publish, retrieve real prices, check what fits what, and say so plainly when the sources contradict each other. When Makita claims 380 products in one block of a page and 440 in another block of the same page, we quote both.

We are not a substitute for a licensed trade. On electrical work, gas, load bearing structure and work at height, the rules are not suggestions: an electrical installation has to meet the code that applies where you live and pass the inspections that go with it. A tool buying site authorises nothing.
