20V MAX 7 1/4 Circular Saw and Lithium Ion Battery Starter Kit

Key Features

1,700 MWO Brushless Power

DEWALT rates this as its most powerful 20V MAX circular saw, with a brushless motor that turns the blade at up to 5,500 RPM to keep framing cuts moving without bogging.

8.0Ah Battery in the Box

The kit ships with the same 8.0Ah XR battery DEWALT used to rate the saw at up to 368 cuts per charge in 2x6 SPF, plus a charger, so it is ready for production work out of the box.

Full-Size Cut Capacity

This 7-1/4" cordless circular saw cuts 2-9/16" deep at 90 degrees and 2" at 45 degrees, enough to clear 2x dimensional lumber in one pass, square or beveled.

Overview

The DeWALT DCS590WW1 20V MAX XR Brushless 7-1/4 in. Circular Saw POWERPACK 8.0Ah Kit is a cordless framing saw kit for carpenters, remodelers, and contractors who want corded-class cutting without the cord. This is a circular saw designed for framing, sheathing, decking, and general crosscuts and rip cuts in lumber and sheet goods. Model Number DCS590WW1 pairs the brushless saw with a high-capacity 8.0Ah XR battery, a fast charger, and a 24-tooth framing blade.

DEWALT calls this saw its most powerful 20V MAX circular saw, rating it at up to 1,700 MWO (max watts out) with a no-load speed of up to 5,500 RPM. In practical terms, the saw holds blade speed through long rips in 2x stock and wet framing lumber instead of slowing down mid-cut. DEWALT's runtime rating of up to 368 cuts per charge in 2x6 SPF was measured with the DCB2108 20V MAX XR 8.0Ah battery, which is the battery included in this kit. That number is the reason to buy the kit rather than pairing the bare saw with a smaller pack.

Cut capacity matches a full-size corded saw. Maximum depth of cut is 2-9/16" at 90 degrees and 2" at 45 degrees, and the shoe bevels to 57 degrees with positive stops at 45 and 22.5 degrees. That covers rafter tails, hip and valley cuts, stair stringers, and beveled deck boards without switching tools.

The layout is a right-blade, top-handle design: the blade sits to the right of the motor and the handle rides on top of the saw. Many framers prefer that configuration because it feels familiar and keeps the saw balanced when cutting off sawhorses or the deck. It is one of the higher-output options in our DeWALT circular saws collection, and it keeps the practical features DEWALT puts on its pro saws. An electric brake stops the blade from coasting after you release the trigger, an onboard LED lights the cut line in dim framing, and an integrated rafter hook lets you hang the saw on a joist or top plate between cuts.

For finish carpentry or indoor work, the optional dust port connects to the DEWALT AirLock system or a standard 1-3/8" (35 mm) dust extractor hose (both sold separately). That makes the saw usable in occupied homes and finished spaces where a plume of sawdust is not acceptable.
