Let me say up front what this isn’t. This isn’t me telling you to bin a DeWalt kit that’s earning its keep — chucking out tools that still do the job because of brand envy is how tradespeople burn money for no reason. This is about one specific moment: the day your batteries finally give up and you’re about to spend real money replacing them.
That’s the only point platform loyalty is genuinely up for negotiation, and it’s exactly the moment most of us skip straight past. We walk into the merchant, grab two more packs because that’s what the tools take, and we’re locked in for another five years without ever asking if it’s still the right call. That’s habit, not decision.
The honest starting point — loyalty is expensive
Tool brands don’t really compete on tools. They compete on the fact that once you’ve got six batteries in the van, you’re not going anywhere. Every bare tool you buy after that is protected by the sunk cost of the packs you already own. Nothing sinister about it — it’s just smart business — but it means the switching window is narrow, and it opens the moment your batteries die.
Once the packs are dead, the sunk cost disappears. Your bare tools are still worth something, the flat batteries are worth nothing, and for a few weeks you’re genuinely free to choose. Spend that window actually thinking instead of reflexively rebuying, and you might save yourself a decade in the wrong ecosystem — or you might confirm DeWalt was right all along, which is just as good an outcome.
What Milwaukee genuinely does better
The battery platform is the big one, and it’s simpler than DeWalt’s. M18 is one system — the little drill driver and the heavy-duty breakers all take the same pack, just in different capacities. DeWalt’s answer to heavy-duty tools was FlexVolt, and it works, but it means juggling 18V XR packs alongside 54V FlexVolt packs and remembering which tool wants which. With Milwaukee it’s just: it’s an M18, put an M18 in it. A genuinely capable brushless kit like the M18 hammer drill and impact driver combo below shows what that platform simplicity buys you — one battery family covering both tools, no second charger to carry.
Packout is the second reason, and it matters more than it looks on paper. Milwaukee’s modular storage system is the most complete one going — the widest spread of boxes, mounts, organisers and van racking on the market, and it keeps growing. DeWalt’s ToughSystem 2.0 is a decent, cheaper alternative, but Packout simply has more of everything. Something like the Packout Compact Slim Organiser below is typical of how deep that range runs — a cheap, specific box for exactly one job, which is what makes the system worth building into.
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 doesn’t make or makes half-heartedly. If you’re a sparks or a plumber, there’s a decent chance Milwaukee makes something for your trade that DeWalt simply doesn’t.
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 isn’t trivial. Milwaukee charges a premium and doesn’t apologise for it.
FlexVolt, for all my complaining 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 heavy FlexVolt tools — the table saws, the big mitre saws, the breakers — are seriously good. The complexity is the price of that cleverness, and plenty of people think it’s worth paying.
And DeWalt’s storage still does the job for a lot less money. A solid ToughSystem 2.0 box like the one below covers general trade use without the Packout premium, which matters if storage isn’t the thing you’re trying to upgrade.
Availability is close to 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 is enormous. There’s also a fair argument that DeWalt tools are simply less precious — if one gets nicked off site, it stings less.
The two platforms at a glance
Battery platform: DeWalt runs XR 18V plus FlexVolt 54V, which means managing two families. Milwaukee runs one M18 family, with High Output packs for more grunt.
Price: DeWalt is lower across the range. Milwaukee sits at a premium, though kit deals narrow the gap.
Heavy tools: FlexVolt is genuinely strong for DeWalt. Milwaukee’s High Output keeps everything on one platform.
Modular storage: ToughSystem 2.0 is good and cheaper. Packout has the widest range on the market.
Trade-specific tools: DeWalt’s line is thinner here. Milwaukee is strong for sparks and plumbers.
Resale value: Both hold up well second-hand.
Best reason to pick it: DeWalt wins on value and FlexVolt’s heavy kit. Milwaukee wins on platform simplicity and trade-specific tools.
The battery maths nobody actually does
Here’s the calculation worth doing before you rebuy. Add up what you’re about to spend on replacement DeWalt packs. Work out what your bare DeWalt tools would fetch second-hand — and be honest, DeWalt resells well, so that number is usually higher than people expect. Then price the equivalent Milwaukee kit, ideally as a kit deal rather than piecemeal, because that’s 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 outcomes — 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, while still running DeWalt day to day, is the worst of both worlds — you pay the premium and end up owning two platforms. If you switch, switch properly.
When you should absolutely stay with DeWalt
If your work is general trade and your tools are doing the job, stay. If you’ve got a heavy FlexVolt tool you rely on, stay — that’s a real asset you’d be writing off. If you’re 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 give it credit for. 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 doesn’t make. It sounds sensible. In practice you end up with two charger sets, two battery piles, a heavier van, and the low-level irritation of grabbing the wrong pack.
It can work, but only if it’s deliberate: one platform is the daily kit, the other is a small, defined set of specialist tools that stays in its own box and doesn’t sprawl. The failure mode is drift — one Milwaukee tool becomes four, and suddenly you’re running two full platforms by accident and paying for both. If you can’t say exactly which tools live on the second platform and why, don’t start.
What I would actually do
If my XR packs died tomorrow, I’d spend an evening doing the sum honestly — replacement battery cost, bare tool resale value, Milwaukee kit deal price — and I’d probably find the gap smaller than my instincts said. Then I’d look hard at whether my trade is one Milwaukee builds specialist tools for. If it is, I’d switch and switch completely. If it isn’t, I’d buy the XR packs and stop thinking about it for another five years.
The worst outcome isn’t choosing DeWalt or choosing Milwaukee. It’s 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 system, 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 the badge.
Can I use DeWalt batteries in Milwaukee tools?
No, and don’t try. Third-party adaptors exist and they’re a bad idea — they void warranties and the battery management isn’t designed for it. Cross-platform battery use isn’t 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’s the one moment the sunk cost disappears. Switching while you’ve got healthy packs means writing off money for no operational gain.
Is Packout worth switching platforms for?
On its own, no — storage isn’t a good enough 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’re already switching for other reasons, not a reason to switch by itself.
Do DeWalt tools hold their value second-hand?
Yes, well. That’s 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 make it.
