Bosch CS10 vs. Dremel US40-04

Let’s take a look at these two circular saws: the Bosch CS10 and the Dremel US40-04.

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 products are corded and run on 120 V. The CS10 draws 15 amps. The US40-04 draws 7.5 amps. Standard U.S. residential circuits are 120 V, 15 A, which will support either of the saws.

The CS10 motor spins at 5600 rpm and the US40-04 motor spins at 13000 rpm. Don’t get too caught up in these numbers, since the manufacturers measure them under ideal conditions, and they don’t have a direct impact on the saw’s real-world ability to handle different material.

Both circular saws 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

The CS10 takes 7 1/4” diameter blades and has a 5/8” arbor. The US40-04 accepts 4” diameter blades. Most 8-to-10” blades have a 5/8” arbor hole, so this size arbor maximizes blade compatibility.

The CS10 can bevel the blade up to 56°, can cut up to 2 7/16” deep at a 90° angle, and can cut up to 1 7/8” at a 45° angle. The US40-04 can bevel up to 0° and can cut up to 3/4” deep at a 90° 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 Bosch has the blade on the right side of the unit. The Dremel 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.
