Choose DeWalt 20V MAX if…
- Enormous range plus FlexVolt 60V batteries that power high-demand saws while staying backward-compatible with 20V tools.
- You shop at Home Depot and want professional-grade tools.
- You'll need high-power tools — FlexVolt 60V covers them.
Choose Milwaukee M18 if…
- The deepest pro/trade ecosystem; M18 FUEL brushless tools are class-leading and the M12 companion line is the best subcompact range.
- You shop at Home Depot and want professional-grade tools.
Neither is universally "better" — match the platform to how you'll use it and where you shop. And remember the real cost is the batteries: once you own three or four, switching platforms gets expensive, so choose the ecosystem you'll grow into.

Common questions
DeWalt 20V MAX or Milwaukee M18 for a homeowner?
DeWalt 20V MAX is the friendlier homeowner pick here — on breadth and availability. The other is aimed at professional use.
Can DeWalt 20V MAX and Milwaukee M18 share batteries?
No — like nearly all cordless brands, the packs are proprietary. That's exactly why the platform choice matters more than any single tool.
What's the catch with each?
DeWalt 20V MAX: High-demand saws want pricier FlexVolt batteries, and the 12V XTREME compact line uses separate batteries. Milwaukee M18: Premium prices; the M12 companion line takes different batteries, and heavy equipment moves to the separate MX FUEL platform.
Still deciding?
If neither of these is quite right, here are the same two platforms against the rest of the field.
