Get the Milwaukee M18 FUEL 2732-20 if:
- You want to hook the saw to a shop vac.
- You want the 5-year warranty.
- You’re on M18 batteries already.
The short answer
Dust port, longer warranty? Milwaukee
Steeper bevels, deeper 45° cuts? DeWalt
Both are brushless 7-1/4 in. cordless saws with an electric brake, an LED and a rafter hook, sold as bare tools. They cut about the same depth at 90° (2-1/2 in. vs 2-9/16 in.). The DeWalt cuts deeper at 45° (2 in. vs 1-7/8 in.) and bevels to 57° vs 50°. The Milwaukee spins a little faster, has a dust port and vacuum adapter built in, and has the longer warranty.
Best for dust control
Pick the Milwaukee M18 FUEL 2732-20 if
- You want to hook up a vacuum. Milwaukee lists an integrated dust port with a vacuum adapter.
- You want the longer warranty: 5 years vs 3.
- You cut a lot per charge. Milwaukee claims up to 750 cuts per charge with an HD12.0 pack.
Tool only 2732-20: the saw, with no battery or charger.
Check the Milwaukee saw on AmazonBest for steep bevels
Pick the DeWalt DCS590B if
- You cut steep bevels. It goes to 57°, with stops at 22.5° and 45°.
- You cut 2x stock at 45°. It cuts 2 in. deep at 45°.
- You already own DeWalt 20V MAX batteries. The DCS590B is part of DeWalt’s 20V MAX XR line.
Tool only DCS590B: DeWalt lists the saw. Battery and charger sold separately.
Check the DeWalt saw on AmazonBefore you buy: I compared the two bare tools. When I checked on Oct 9, 2026, both listings were sold by third-party sellers rather than Amazon, and the Milwaukee listing was in non-retail packaging. Milwaukee’s warranty covers tools bought from an authorized Milwaukee distributor. Listings change, so check who the seller is and that it’s new before you order.

This counts the rows below where one is clearly better. It’s a tally, not an overall rating. The DeWalt’s wins are about angles. The Milwaukee’s are about dust, speed and warranty.
A green check means that number or feature is clearly better. No check means it's a tie, the gap is tiny, or the makers measure it differently. Every figure comes from Milwaukee or DeWalt, not from Amazon.

Spec notes
- Depth at 90°: DeWalt’s product page and manual both list 2-9/16 in. That’s only 1/16 in. more than the Milwaukee’s 2-1/2 in., so the row isn’t scored.
- Speed: DeWalt’s product page lists up to 5,500 rpm no-load.
- Dust: DeWalt’s spec list says “Dust Collection: Yes,” but its feature list calls the dust port optional and sold separately. This page goes with sold separately.
- Left out: weight (Milwaukee’s published figures don’t agree with each other, and DeWalt’s page lists only an assembled product weight), the DeWalt’s arbor size (not listed on DeWalt’s page), blade side (not confirmed on both makers’ pages), and cuts per charge (the two claims use different batteries and test boards).
What it can handle
These are common circular-saw cuts, checked against each maker’s published depth and bevel limits. I haven’t tested either saw. If a cut is past a published limit, it gets a CAN’T.
- Can do Inside the maker's limits, with what's in the box
- Just barely At the maker's limit, or needs a part sold separately
- Can’t Past the maker's limit, or not something they support

Depths are the makers’ maximums with a 7-1/4 in. blade. Set the blade about 1/4 in. below the board for most cuts.
Notes and sources
How the verdicts were made: depth and bevel limits come from the operator’s manuals and product pages. Nothing here comes from hands-on testing or owner reviews.
4x4: a 4x4 is 3-1/2 in. thick, past both saws’ depth. Cut from both sides or use a bigger saw.
Dust hookup: DeWalt says its optional dust port works with the DeWalt AIRLOCK system or a standard 35 mm dust extractor. The port is sold separately, so the DeWalt gets JUST BARELY.
