Bosch CS10 vs. Worx WX439L

We’ll take a look at these two circular saws: the Bosch CS10 and the Worx WX439L.

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

Both products are corded and require 120 V. The CS10 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 CS10 motor produces 5600 rpm and the WX439L motor produces 4100 rpm. Don’t pay too much attention to these numbers, because the manufacturers measure them under no-load conditions, so they don’t have a useful impact on the saw’s real-world capability to handle different material.

The CS10 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 CS10 accepts 7 1/4” diameter saw blades and has a 5/8” arbor. The WX439L takes 4 1/2” diameter blades and has a 3/8” arbor. Most 8-to-10” blades have a 5/8” arbor hole, so this size of arbor maximizes blade compatibility.

The CS10 can bevel the blade up to 56°, is able to cut up to 2 7/16” at an angle of 90°, and can cut up to 1 7/8” 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 Bosch has stops at 22.5° and 45°.

The Bosch 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.
