Worx WX429L vs. Worx WX439L

Let’s compare these two Worx circular saws: the Worx WX429L and the Worx WX439L.

Features & Benefits

You can read our roundup of the best compact circular saws.

Power & Motor

Both circular saws are corded and run on 120 V. The WX429L draws 4 amps. The WX439L draws 4.5 amps. Standard U.S. residential circuits are 120 V, 15 A, which will support either of the saws.

The WX429L has a motor that spins at 3500 rpm and the WX439L has a motor that spins at 4100 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.

Both products have a direct drive motor.

Blades & Capacity

Both circular saws take 4 1/2” diameter blades and have a 3/8” arbor.

Both saws can bevel their blades up to 45°, can cut up to 1 11/16” deep at an angle of 90°, and are able to cut up to 1 1/8” at a 45° angle.

Both products have the blade mounted on the left side of the saw. 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.
