Best Cordless Circular Saws in 2027

The DCS578B ranks first on our spec sheet. It runs at 5800 rpm with no load, which ties for the highest speed among the 10 saws. Higher speed helps the blade pass through framing lumber without bogging down. It is a 60V FLEXVOLT model, so it pulls from a larger battery platform than the 20V saws here.

Depth of cut is 2.5625 in at 90°, tied for the deepest in the lineup. That is enough to cut through dimensional lumber in one pass, which is what most framing jobs need. The bevel reaches 57°, the widest of all the saws that list it. That helps with angled rafter and roof cuts.

At 9.92 lb, it is not the lightest. Milwaukee's saw weighs 7.2 lb. The maker's listing does not publish battery energy, so runtime is hard to judge from the data. It has an electric brake that stops the blade after you release the trigger, plus an LED light and a rafter hook.

Weight is where the Milwaukee stands out. At 7.2 lb, it is the lightest of the five 7-1/4 in saws on this page. The next lightest is the DEWALT DCS578B at 9.92 lb. A lighter saw is easier to hold overhead and on roofs, and it tires your arm less over a long day.

Cutting numbers are good but not the highest. No-load speed is 5000 rpm, and depth of cut at 90° is 2.5 in. That is slightly shallower than the 2.5625 in on the DEWALT DCS578B. The bevel reaches 50°, which covers common angled cuts but stops short of the 57° on the DEWALT.

The name says bare, so plan on a separate battery and charger. The maker does not publish battery energy here, so runtime cannot be compared. The guards are magnesium, and there is an LED light, a rafter hook and a dust port on the guard. An electric brake stops the blade after you release the trigger.

The DCS577B shares the highest no-load speed in the group at 5800 rpm. That speed keeps the blade moving fast through wood, which gives smoother cuts. It is a 60V FLEXVOLT saw with a brushless motor. The listing says the motor is built for long runtime, but the maker does not publish battery energy.

Depth of cut at 90° is 2.44 in, a little under the 2.5625 in that the top-ranked DEWALT reaches. Bevel capacity is 53°, with stops at 45° and 22.5° per the listing. At 10.9 lb it is heavier than the DCS578B at 9.92 lb and the Milwaukee at 7.2 lb, so it is less comfortable for long overhead work.

The dust blower, which the top two saws do not list, clears sawdust from the cut line so you can see your mark. It also has an electric brake, a magnesium shoe and a rafter hook. The blade sits to the left of the motor, with the handle at the rear.

This is a kit, and the battery shows it. The listed battery energy is 160 Wh, the second highest of the six saws that list it. The listing claims up to 368 cuts per charge. Runtime is the main reason to pick it, since buyers of cordless saws often worry about running out of power mid-job.

The cost is weight. At 15.05 lb it is the heaviest saw on the page, more than double the 7.2 lb Milwaukee. That matters on ladders and roofs. Cutting specs are strong: 5500 rpm no-load and a 2.5625 in depth at 90°, which ties for the deepest here.

The maker does not publish a maximum bevel angle, though the listing gives a 2 in depth of cut at 45°. It has an electric brake. It does not list a dust blower or a laser guide. This is a better fit for long cutting sessions at a work site than for lifting overhead.

Runtime is the Skil's strongest suit. Its listed battery energy is 200 Wh, the highest of the six saws that list it. The listing says two 5.0Ah PWR CORE 20 batteries make up the 40V system and claims up to 600 cuts per charge, based on 2 × 4 crosscuts in SPF lumber.

It is also a balanced cutter. Depth of cut at 90° is 2.5625 in, tied for the deepest, and the bevel reaches 53°. No-load speed is 5300 rpm, lower than the 5800 rpm on the two 60V DEWALT saws. At 10.23 lb it is lighter than the DCS577B and far lighter than the DCS590WW1, which also lists a big battery.

It adds an electric brake and a dust blower. The listing also describes a dual-port charger that takes both batteries from 0-25% in 15 minutes and to full in under an hour. The listing calls the motor digital brushless.
