DeWalt Circular Saws: Cordless 20V, FlexVolt and Corded Picks

Best for
Cordless 7-1/4 inch cuts on 20V

Best for
Light trim and plywood cuts on 20V packs

The DEWALT 20V MAX Circular Saw, model DCS391B, is the compact option with a 6-1/2 inch blade. It comes with an 18-tooth carbide-tipped blade and reaches a maximum depth of 2-1/8 inches at 90 degrees and 1-5/8 inches at 45 degrees, enough for 3/4 inch plywood and standard 2x lumber in a single pass at 90.

The bevel runs from 0 to 50 degrees, and the shoe is magnesium, which keeps weight down while holding accuracy over time. Keyless blade changes with a spindle lock make swaps quick. The feature text says 5,150 RPM while the spec table says 5,100 RPM, a small inconsistency. It carries a 3 year limited warranty, and the battery and charger are sold separately.

Pick this for cutting shelves, trim and panels where maneuverability matters more than depth. If you need to cut through thicker stock or want more power on long plywood rips, the DCS590B is the step up.

• 6-1/2 inch blade, 18T carbide included
• 0-50° bevel
• Magnesium shoe
• Keyless blade change, 3 year limited warranty

The DEWALT 20V MAX XR Brushless Cordless 7-1/4 inch circular saw, model DCS590B, is described as DeWalt’s most powerful 20V MAX circular saw, rated up to 1,700 max watts out. Its brushless motor spins up to 5,500 RPM with no load and delivers up to 368 cuts per charge, according to the listing.

Maximum depth of cut is 2-9/16 inches at 90 degrees and 2 inches at 45 degrees, matching a full-size corded saw. An electric brake stops the blade from coasting after you release the trigger, which improves safety and keeps cuts cleaner. The blade sits to the right of the motor with a top handle, the classic sidewinder layout. It weighs 9.88 pounds and is sold as a tool only. The listing’s bevel detail is cut off, so the maximum bevel angle is not specified.

This is the best cordless choice for building a desk or a setup wall from full sheets without dragging a cord across the floor. For a deeper look at this class of saw, our DeWalt brushless circular saw guide covers more options.

The DEWALT Circular Saw DWE575SB is a corded 7-1/4 inch saw with a 15 amp motor and a 57 degree bevel capacity, the deepest bevel listed here, with stops at 45 and 22.5 degrees. It adds an electric brake to the standard DWE575 design.

At 8.8 pounds, the listing says it is among the lightest saws in its class. Depth of cut is 2-9/16 inches. A ball bearing lower guard is built for long life in harsh environments and improves performance on bevel cuts and shims, and a high-grade aluminum base supports accurate cuts. It runs at 5,200 RPM on 120 volts. The spec table lists a 45 degree cutting angle, which conflicts with the 57 degree bevel in the features; the feature text is the more specific figure.

Choose this if you work in a garage or shop with power nearby and want unlimited runtime. It is the most practical way to cut stacks of MDF for a custom desk without managing batteries.

• 15 amp motor, 5,200 RPM
• 57° bevel with 45° and 22.5° stops
• Electric brake
• 8.8 lb, aluminum base

The DEWALT 7-1 4-Inch Circular Saw DWE575 is the corded 7-1/4 inch saw without the SB model’s electric brake in its feature list. It has a 15 amp motor, 2-9/16 inch depth of cut and weighs 8.8 pounds. Toughcord protection guards against cord pull-outs, and an integrated dust blower keeps the cut line visible.

The listing is inconsistent in several places. The features say 53 degree bevel, while the description says 57 degrees. The spec table lists brushless, lithium-ion batteries, 120 watts, a rectangular blade and aluminum as the surface, none of which fits a corded wood saw, and it gives 4,500 RPM. Trust the feature text and description over the spec fields.

Choose this if the dust blower and Toughcord matter more to you than an electric brake. If you want the brake, the DWE575SB is the better pick for about the same weight. Our DeWalt 7-1/4 circular saw roundup goes further into the corded range.

The Circular Saw for Dewalt 20V Max batteries is made by SXBSXB, not DeWalt. It is a bare tool designed to run on DeWalt 20V packs, and the listing names DCB200, DCB201, DCB203, DCB204, DCB206 and DCB207 as compatible. DeWalt’s warranty does not cover it.

It uses a 7-inch blade in a right-blade layout with a brushless motor rated up to 8,000 RPM, a safety lock and a non-slip handle. The kit includes two 7-inch 30-tooth blades, a parallel guide, a hex wrench, safety glasses and work gloves. The listing gives the bevel as 0 to 40 degrees in the features and 0 to 45 degrees in the title, and it does not state a maximum depth of cut.

This suits a hobbyist who already owns DeWalt 20V batteries and wants an inexpensive saw for occasional cuts. For frequent or precise work, the genuine DCS590B is the more dependable choice.

Best for
Framing and heavy cuts with FLEXVOLT packs

The DEWALT FLEXVOLT 60V MAX* Circular Saw, model DCS577B, is a cordless worm drive style saw for framing. The blade sits to the left of the motor and the handle is at the rear, which improves line of sight for right-handed users on long rips. It uses a brushless motor at 5,800 RPM with an electronic brake.

Bevel capacity is 53 degrees with stops at 45 and 22.5 degrees, and depth of cut is 2-7/16 inches at 90 degrees. It has a magnesium shoe, a rafter hook, an integrated dust blower and onboard blade wrench storage. It weighs 10.9 pounds, the heaviest here, and needs a FLEXVOLT battery, sold separately.

Choose this for framing lumber, thick hardwood slabs for desk tops or all-day cutting. For typical plywood projects, the lighter 20V DCS590B is easier to handle.
