DeWalt DCS578 vs. DeWalt DWE575SB

Let’s take a look at these two DeWalt circular saws: the DeWalt DCS578 and the DeWalt DWE575SB.

Features & Benefits

You can read more in our roundup of the best full-size circular saws.

Power & Motor

The DWE575SB is corded, runs on 120 V, and draws 15 amps. Standard U.S. residential circuits are 120 V, 15 A, which will support the.

The DCS578 is cordless and runs on 60 V batteries.

The DCS578 motor spins at 5800 rpm and the DWE575SB motor spins at 5200 rpm. Don’t get too caught up in these numbers, since the manufacturers measure them under ideal conditions, and they don’t have a direct impact on the saw’s real-world ability to handle different material.

Both products have a direct-drive motor. Direct-drive motors are usually lighter than other styles, but their side mounting makes the saw a little harder to control.

Blades & Capacity

Both circular saws accept 7 1/4” diameter blades and have a 5/8” arbor. Most 8-to-10” blades have a 5/8” arbor hole, so this size of arbor maximizes blade compatibility.

Both saws can bevel up to 57°, can cut up to 2 9/16” deep at a 90° angle, and can cut up to 2” at a 45° angle.

When beveling the saw, most circular saws will have positive stops at common angles such as 45° and 90°. This ensures you are making precise cuts. Some saws have additional stops at other angles.

Both products have stops at 22.5°, 45°.

Both circular saws have the blade on the right side of the unit. Right-handers sometimes find it easier to see and control blades mounted to the left, while left-handers might find the same true for right-mounted blades.
