Can I use DeWalt batteries on Milwaukee tools, or mix brands with an adapter?

Not natively — every major platform uses a proprietary mount and communication protocol. Cross-brand adapters exist, but they typically bypass the communication between the pack's battery management system and the tool, they void warranties, and they are a poor idea on high-draw tools like saws and grinders. Treat batteries as brand-locked when you plan your purchases, because economically they are.

Is DeWalt's 20V MAX more powerful than an 18V platform?

No. It is the same electrical class. A five-cell lithium-ion pack is rated around 3.6V per cell nominal and about 4V per cell fresh off the charger — roughly 18V nominal and 20V maximum for the same pack. US marketing quotes the maximum, most other markets quote the nominal. Compare tools on their actual performance, not on the number printed near the battery.

What does 'bare tool' actually mean?

A bare tool (sometimes 'tool only') ships with no battery and no charger. It is priced well below the same tool as a kit, because the batteries are where much of the cost sits. Bare-tool pricing is the reward for staying on one platform: your existing packs power every new tool, so each addition costs much less than your first kit did.

Is Ryobi ONE+ really good enough for a homeowner?

For most homeowners, yes. Ryobi has kept the same ONE+ 18V battery mount compatible since 1996 — a compatibility run no premium brand matches — and the catalog spans hundreds of products. The tradeoffs are typically slower work rates, more plastic in the construction, and less durability under daily jobsite abuse. For furniture, shelves, and seasonal projects, those tradeoffs rarely matter.

Makita LXT or XGT — which should a new buyer pick?

They are two separate battery ecosystems: LXT is the long-running 18V line with one of the largest tool catalogs in the industry, while XGT is the newer 40V max (36V nominal) line aimed at high-demand work like large saws and outdoor equipment. XGT packs do not fit LXT tools. If your needs are general-purpose, LXT's breadth is the safer bet; if you know you need sustained high power, start in XGT and accept the smaller catalog.

Your First Cordless Drill Decides the Next Ten Tools You Buy: DeWalt 20V MAX vs Milwaukee M18 vs Makita vs Ryobi ONE+

Cordless brands sell battery platforms, not tools. Once you own two packs and a charger, bare tools cost far less than kits — so your first purchase quietly decides every one after it. How lock-in economics work, what bare-tool pricing means, and which ecosystem fits homeowners, DIYers and pros.

The short answer

If you skim nothing else: pick the battery platform first, then buy tools into it for the next decade.

You earn a living with tools, or want to: Milwaukee M18 or DeWalt 20V MAX. Both catalogs are deep enough that you will never be the person waiting on a battery adapter that shouldn’t exist.
You are a serious DIYer who finishes basements and builds furniture: Makita LXT or DeWalt 20V MAX. Strong mid-range value, enormous tool selection, batteries that hold up.
You hang shelves, assemble furniture, and fix things a few weekends a year: Ryobi ONE+, and do not let anyone talk you out of it. The premium platforms solve problems you do not have.

The rest of this article is the reasoning — because the way cordless tools are priced is genuinely not obvious the first time you buy one, and the first purchase is the one that locks you in.

The tool is the razor. The battery is the blade.

Walk the cordless aisle and you will see the same product sold two ways: a “kit” with a battery and charger in the box, and a “bare tool” — the tool alone — at a much lower price. The gap between those two prices is the entire business model.

Battery packs are the expensive part. A genuine high-capacity pack contains name-brand lithium-ion cells, a battery management system (BMS) that monitors temperature and per-cell voltage, and the electronics that let the pack talk to the tool and charger. That is why a single genuine 5Ah battery is often priced in the same territory as an entry-level bare tool, and why every brand is delighted to discount the drill if it gets its battery mount into your garage.

Once you own two packs and a charger, the economics flip in your favor. Every subsequent tool can be a bare tool. Your third, fourth, and fifth tools each cost dramatically less than they would as kits — provided you stay on the platform. Switch brands and the meter resets: new batteries, new charger, and a drawer of orphaned packs that fit nothing you own.

That is the lock-in, and it compounds. After five tools, leaving a platform means re-buying hundreds of dollars of batteries just to stand still. The rational move is to treat the first kit purchase as a ten-year decision, because in practice it is one.

One decoding note before the brands: 20V and 18V are the same thing

DeWalt’s platform is called 20V MAX. Milwaukee, Makita, and Ryobi call theirs 18V. Electrically, these are the same class of pack: five lithium-ion cells in series, rated around 3.6V per cell nominal and roughly 4V per cell fresh off the charger. Multiply it out — about 18V nominal, about 20V maximum. US marketing quotes the peak; most of the world quotes the nominal. The fine print on a 20V MAX pack typically says exactly this.

So no platform on this page wins on voltage. Capacity (Ah), cell quality, motor design, and the electronics between them decide performance. Keep that in mind whenever a spec sheet leads with the biggest number it can legally print.

DeWalt 20V MAX: the default choice, and defensible

DeWalt’s 20V MAX line is the platform you buy when you want to stop thinking about platforms. The catalog is enormous — on the order of 250 tools by DeWalt’s own count — retail availability is everywhere in the US, and the yellow tools are so common on jobsites that spare batteries and chargers are never far away.

Its cleverest trick is FlexVolt: larger packs rated 60V max that automatically reconfigure to run on 20V MAX tools. One battery family serves both a compact drill and a full-size circular saw, which is exactly the kind of long-term flexibility a platform decision is supposed to buy you.

Who it fits: pros who are not already committed elsewhere, and serious DIYers who want pro-grade durability with the widest possible upgrade path.

Milwaukee M18: the trades’ platform

Milwaukee’s M18 system runs on the order of 250 tools, and the FUEL sub-brand — its brushless, highest-output tier — is the benchmark most competitors get measured against. Where Milwaukee pulls ahead is specialty depth: press tools, PEX expanders, cable cutters, drain equipment. If you are a plumber or an electrician, the tool you need on an M18 battery almost certainly exists, which is not something every platform can say.

One caution: Milwaukee also sells M12, a separate compact 12V line with its own batteries. It is excellent, but M12 and M18 packs do not interchange. Plenty of tradespeople happily run both; just know you are buying two ecosystems, not one.

Who it fits: full-time trades, anyone whose tools work for a living, and buyers who want the deepest specialty catalog in cordless.

Makita LXT and XGT: superb tools, one complication

Makita’s 18V LXT platform has been running since 2005 and claims one of the largest 18V catalogs in the industry — on the order of 300 tools. The tools themselves are known for refined ergonomics and smooth brushless motors; Makita’s impact drivers in particular (the TD-series sold in Japan is the enthusiast benchmark) have a devoted following. For high-demand tools, LXT’s X2 approach pairs two 18V packs for 36V of output without a new battery type.

The complication is XGT, Makita’s newer 40V max (36V nominal) platform for sustained high-power work. XGT batteries do not fit LXT tools, and vice versa. Makita positions the two lines as complementary, but a new buyer has to pick a primary ecosystem — and hedging across both means double batteries and double chargers, which defeats the entire economic logic above.

Who it fits: serious DIYers and finish-focused pros who value refinement, and buyers outside high-demand concrete/outdoor work, for whom LXT’s breadth is the safer bet.

Ryobi ONE+: the honest answer most buyers should hear

Here is the section tool marketing does not want written: most homeowners should not buy a premium platform.

Ryobi’s ONE+ 18V system has kept the same battery mount compatible since 1996 — a pack you buy today fits tools sold decades apart, a compatibility run no premium brand matches. The catalog spans hundreds of tools and oddities no one else bothers with: glue guns, inflators, misting fans, soldering irons. It is sold in every Home Depot in America, and it is priced for people who buy a tool when a project needs one.

The tradeoffs are real. Ryobi tools typically run slower, weigh more for the same output, use more plastic where premium brands use metal, and are not built for the drop-off-a-ladder, hundred-holes-a-day life. A tradesperson would wear one out.

But if your drill lives in a closet and comes out one weekend a month, those tradeoffs cost you nothing. The shelf gets hung either way. Spending three times as much for duty-cycle headroom you will never use is not buying quality — it is buying jewelry. The cheap option is not just acceptable here; it is the correct engineering choice for the load.

When to skip Ryobi: you use tools weekly, you drive lag bolts or mix concrete, or you already know this hobby is escalating. Buy once into a premium platform instead of buying twice.

How to actually decide in one evening

List the next five tools you will realistically own. Not the fantasy shop — the real list. Drill, impact driver, circular saw, and then what? Blower? Trim router? PEX expander?
Check that your candidate platform sells each one as a bare tool. This is where specialty needs eliminate options fast.
Buy one combo kit with two batteries and a charger. Kits bundle the batteries at the best effective rate you will ever get on the platform.
Buy everything after that bare. This is the payoff of steps 1–3, and it only works if you resist the aisle-end kit deals for tools you already have batteries for.
Buy genuine batteries. Aftermarket packs are cheaper because they typically economize on cells and BMS protection — the two things you cannot see and the two things that matter. With lithium-ion at these capacities, that is not the corner to cut.

One last thing before you commit a decade of purchases to a platform: not every problem is a cordless problem. A surprising share of stripped screws is a hand-tool mismatch — see JIS vs Phillips screwdrivers.

Caveats

Catalog sizes and compatibility claims are manufacturer-published figures and change as lines expand; treat counts like “250 tools” as the order of magnitude they are, not an inventory. We have not bench-tested the tools named here. Prices move constantly and vary by bundle, which is why none appear above — check the current price at the links before assuming any platform is the cheap or expensive one this week, because promotional kit pricing regularly scrambles the usual hierarchy.
