What is included with the DCS571B?

The kit includes the saw, one wood cutting blade, a blade change key, a dust port adaptor and a rip fence. A 5Ah battery kit is also listed in the bundle.

How deep does it cut?

It cuts 1-9/16 inches at 90 degrees and 1 inch at 45 degrees, enough for 2x material at 90 and 1x at 45.

Does it use the same batteries as other DeWalt 20V tools?

Yes, it runs on any DeWalt 20V MAX battery, so it shares packs with the rest of the platform.

For trim, siding and quick 2x cuts, yes. For deep cuts in thick lumber or heavy framing, a 7-1/4-inch saw is the better tool.

Our take on the DeWalt DCS571B ATOMIC 20V MAX 4-1/2" Circ Saw

The DeWalt DCS571B is a compact 20V MAX brushless circular saw with a 4-1/2-inch blade, built for one-handed trim and framing work. Its bevel gear lets it crosscut 2x material at 90 degrees and 1x at 45 degrees, which most small saws cannot do. It weighs 5.5 lbs and spins at 4,500 RPM, with an electronic blade brake, on-board blade key storage, a rip fence and a dust port. It suits remodelers and DIYers who want a light saw for quick cuts; a full-size 7-1/4-inch saw cuts deeper and faster on heavy framing.

About the DeWalt DCS571B ATOMIC 20V MAX 4-1/2" Circ Saw

This is a 20V MAX brushless cordless circular saw with a 4-1/2 in. blade. Its bevel gear design cuts 2x material at 90 degrees. The bevel lever tilts to 45 degrees to cut 1x dimensional lumber. The elongated handle gives better reach for rip cutting OSB and plywood.

With a DCB205 battery, the brushless motor can cut up to 339 linear feet of 3/4 in. OSB. An electronic blade brake stops the blade quickly. The 1-1/2 in. finger trigger lets you choke up on the tool, and the auxiliary handle is removable.

An on-board dust port helps control dust, and the blade key stores on the tool for blade changes. A hang hook is built in. This is the tool-only model, so the battery and charger are sold separately.
