Bosch CS10 vs. DeWalt DCS578

Let’s compare these two circular saws: the Bosch CS10 and the DeWalt DCS578.

Features & Benefits

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

Power & Motor

The CS10 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 requires 60 V batteries.

The CS10 motor produces 5600 rpm and the DCS578 motor produces 5800 rpm. But don’t pay too much attention to these numbers, because the manufacturers measure them under no-load conditions, so they don’t have a strong impact on the saw’s real-world capability 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 take 7 1/4” diameter saw blades and have a 5/8” arbor. Most 8-to-10” blades have a 5/8” arbor hole, so this size of arbor provides a lot of choices.

The CS10 can bevel the blade up to 56°, is able to cut up to 2 7/16” at a 90° angle, and will cut up to 1 7/8” deep at 45°. The DCS578 can bevel its blade up to 57°, can cut up to 2 9/16” at an angle of 90°, and is able to cut up to 2” deep 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.

The Bosch has stops at 22.5° and 45°. The DeWalt has stops at 22.5°, 45°.

Both saws have the blade on the right 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.
