We’ll take a look at these two circular saws: the DeWalt DCS578 and the Worx WX429L.

Features & Benefits

For more information, read more in our roundup of the best compact circular saws and the best full-size circular saws.

Power & Motor

The WX429L is corded, requires 120 V, and draws 4 amps. In the U.S., standard residential circuits are 120 V, 15 A, which will support the.

The DCS578 is cordless and runs on 60 V batteries.

The DCS578 has a motor that spins at 5800 rpm and the WX429L has a motor that spins at 3500 rpm. You shouldn’t get too caught up in the RPM numbers, since the manufacturers test them under ideal conditions, and they don’t have a direct correlation with the saw’s real-world ability to handle various types of material.

The DCS578 has a direct-drive motor. The WX429L has 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

The DCS578 takes 7 1/4” diameter blades and has a 5/8” arbor. The WX429L accepts 4 1/2” diameter saw blades and has a 3/8” arbor. Most 8-to-10” blades have a 5/8” arbor hole, so this size arbor won’t limit your choices.

The DCS578 can bevel its blade up to 57°, can cut up to 2 9/16” deep at 90°, and will cut up to 2” at a 45° angle. The WX429L can bevel the blade up to 45°, is able to cut up to 1 11/16” deep at an angle of 90°, and can cut up to 1 1/8” at 45°.

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.

The DeWalt has stops at 22.5°, 45°.

The DeWalt has the blade on the right side of the unit. The Worx has the blade on the left side of the body. 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.
