Features & Benefits

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

Power & Motor

Both circular saws are corded and run on 120 V. The DWE575SB draws 15 amps. The WX439L draws 4.5 amps. In the U.S., standard residential circuits are 120 V, 15 A, which will support either of the saws.

The DWE575SB motor spins at 5200 rpm and the WX439L motor spins at 4100 rpm. Dont get too caught up in these numbers, since the manufacturers measure them under ideal conditions, so they dont have a direct impact on the saws real-world capability to handle different material.

The DWE575SB has a direct-drive motor. The WX439L 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 DWE575SB takes 7 1/4 diameter blades and has a 5/8 arbor. The WX439L accepts 4 1/2 diameter blades and has a 3/8 arbor. Most 8-to-10blades have a 5/8arbor hole, so this size arbor maximizes blade compatibility.

The DWE575SB can bevel its blade up to 57°, is able to cut up to 2 9/16 at an angle of 90°, and can cut up to 2 deep at 45°. The WX439L can bevel up to 45°, will cut up to 1 11/16 at a 90° angle, and is able to cut up to 1 1/8 deep at an angle of 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 saw. The Worx has the blade on the left 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.
