Let me be clear about what this is and is not. This is not a piece telling you to bin a working DeWalt kit. If your XR gear is doing the job, keep it – replacing functional tools out of brand curiosity is how people waste thousands. This is about one specific moment: the day your batteries are done and you are about to spend real money replacing them.
That moment is the only time platform loyalty is genuinely up for negotiation, and it is exactly the moment most of us do not negotiate at all. We walk into the merchant, buy two more XR packs because that is what the tools take, and lock ourselves in for another five years without once asking whether it is still the right call. That is a habit, not a decision.
The honest starting point: loyalty is expensive
Tool brands do not really compete on tools. They compete on the fact that once you own six batteries, you are never leaving. Every bare tool you buy afterwards is profit protected by the sunk cost of your packs. That is a smart business model and there is nothing sinister about it – but it means the switching decision only exists in a narrow window, and both DeWalt and Milwaukee know exactly when that window is.
When your packs die, the sunk cost evaporates. Your bare tools are worth something, your dead batteries are worth nothing, and for a few weeks you are actually free to choose. Spend that window thinking rather than reflexively rebuying, and you might save yourself a decade of buying into the wrong ecosystem. Or you might confirm DeWalt is right for you – which is also a good outcome, just an informed one.
What Milwaukee genuinely does better
The battery platform is simpler, and this is the biggest one. M18 is one system. Every M18 tool, from the little drill driver to the heavy breakers, takes M18 packs – the High Output packs deliver more, but they are the same mount, same charger, same family. DeWalt’s answer to heavy tools was FlexVolt, which works, but it means you are now managing 18V XR packs and 54V FlexVolt packs and thinking about which tool wants which. Milwaukee’s story is just: it is an M18, put an M18 in it.
Packout is the second, and it is a bigger deal than it looks on paper. Milwaukee’s modular storage ecosystem is the most complete on the market – the widest range of boxes, mounts, organisers and van racking. DeWalt’s ToughSystem 2.0 is good and it is cheaper, but Packout has more of everything and the accessory range keeps growing. If storage is a real part of how you work, that ecosystem is worth money.
The third is the specialist end. Milwaukee has been aggressive about building tools for specific trades – pipe tools, cable tools, plumbing and electrical kit that DeWalt either does not make or makes half-heartedly. If you are a sparks or a plumber, there is a decent chance Milwaukee makes something for your trade that DeWalt simply does not.
What DeWalt still does better
Price, consistently. DeWalt tools and batteries generally cost less than the Milwaukee equivalent, and across a full kit that gap is not trivial. Milwaukee charges a premium and does not apologise for it.
FlexVolt, despite what I said above, is genuinely clever engineering. A pack that reconfigures itself between 18V and 54V depending on the tool is a real solution to a real problem, and the FlexVolt heavy tools – the table saws, the big mitre saws, the breakers – are seriously good. The complexity I complained about is the price of that cleverness, and plenty of people think it is worth paying.
Availability is a wash in the UK now, but DeWalt has a slight edge in the number of places you can walk in and buy it, and its range in the general-trade middle ground remains enormous. And there is a fair argument that DeWalt’s tools are simply less precious – if a DeWalt gets nicked off site, it stings less.
The two platforms at a glance
The two platforms, honestly compared:
| Factor | DeWalt (XR / FlexVolt) | Milwaukee (M18) |
| Battery platform | XR 18V + FlexVolt 54V to manage | One M18 family, High Output for more grunt |
| Price | Lower across the range | Premium, kit deals narrow the gap |
| Heavy tools | FlexVolt is genuinely strong | High Output, stays on one platform |
| Modular storage | ToughSystem 2.0 – good, cheaper | Packout – widest range on the market |
| Trade-specific tools | Thinner | Strong for sparks and plumbers |
| Resale value | Strong | Strong |
| Best reason to pick it | Value and FlexVolt heavy kit | Platform simplicity and trade tools |
The battery maths nobody actually does
Here is the calculation worth doing before you rebuy. Add up what you are about to spend on replacement DeWalt packs. Then work out what your bare DeWalt tools would fetch second hand – and be honest, DeWalt resells well, so this number is usually higher than people expect. Then price the equivalent Milwaukee kit, ideally as a kit deal rather than piecemeal, because the kit deals are where the premium mostly disappears.
For a lot of people the answer comes out closer than they assumed. Selling four or five bare tools that still work, plus not buying batteries you were about to buy anyway, funds a surprising amount of a Milwaukee kit. For plenty of others it comes out clearly in DeWalt’s favour, and they rebuy XR with confidence instead of habit. Both are fine. The point is doing the sum.
What kills the maths every time is doing it piecemeal. Buying one Milwaukee tool with a battery, then another, then another, while still running DeWalt is the worst of both worlds – you pay the premium and you own two platforms. If you switch, switch properly and use the moment.
When you should absolutely stay with DeWalt
If your work is general trade and your tools are doing it, stay. If you have a heavy FlexVolt tool you rely on, stay – that is a real asset you would be writing off. If you are price sensitive, stay, because Milwaukee will cost you more and no amount of Packout enthusiasm changes that. And if your crew runs DeWalt, stay, because being the one bloke on a different platform means never borrowing a battery again.
That last one is worth more than people credit. Platform commonality across a team is a genuine operational advantage, and breaking it for personal preference is an expensive kind of stubbornness.
The middle path, and why it usually fails
The tempting compromise is running both – keep DeWalt for the general stuff, add Milwaukee for the trade-specific tools DeWalt does not make. It sounds sensible. In practice you end up with two charger sets, two battery piles, a heavier van, and the constant low-level irritation of grabbing the wrong pack.
It can work, but only if it is deliberate: one platform is the daily kit, the other is a small, defined set of specialist tools that stays in its own box and does not sprawl. The failure mode is drift – one Milwaukee tool becomes four, and now you are running two full platforms by accident and paying for both. If you cannot state exactly which tools live on the second platform and why, do not start.
What I would actually do
If my XR packs died tomorrow, I would spend an evening doing the sum honestly – replacement battery cost, bare tool resale value, Milwaukee kit deal price – and I would probably find the gap smaller than my instincts said. Then I would look hard at whether my trade is one Milwaukee builds specialist tools for. If it is, I would switch and switch completely. If it is not, I would buy the XR packs and stop thinking about it for another five years.
The worst outcome is not choosing DeWalt or choosing Milwaukee. It is spending four figures on batteries without noticing you made a decision at all.
Frequently asked questions
Is Milwaukee actually better than DeWalt?
Not straightforwardly. Milwaukee has a simpler battery platform, the strongest modular storage ecosystem, and more trade-specific tools. DeWalt is cheaper, has FlexVolt for the heavy end, and a huge general-trade range. Better depends on your trade and your budget, not on the badge.
Can I use DeWalt batteries in Milwaukee tools?
No, and you should not try. Third-party adaptors exist and they are a bad idea – they void warranties and the battery management is not designed for it. Cross-platform battery use is not a real option.
Is FlexVolt better than Milwaukee High Output?
They solve the same problem differently. FlexVolt reconfigures between 18V and 54V for genuinely heavy tools. High Output stays within M18 and delivers more current. FlexVolt goes harder at the very heavy end; High Output keeps everything on one platform. Which is better depends on whether you actually run heavy tools.
When is the right time to switch platforms?
Only when your batteries need replacing. That is the one moment the sunk cost disappears. Switching while you have healthy packs means writing off money for no operational gain.
Is Packout worth switching platforms for?
On its own, no – storage is not a good reason to change your entire tool ecosystem, and ToughSystem 2.0 is a capable system for less money. Packout is a reason to prefer Milwaukee if you are already switching for other reasons, not a reason to switch by itself.
Do DeWalt tools hold their value second hand?
Yes, well. That is exactly why the switching maths is worth doing properly – your bare tools are worth more than most people assume, and that resale value is what funds the move if you decide to mak
