Black+Decker BDCCS20C vs. Bosch CS10

Let’s take a look at these two circular saws: the Black+Decker BDCCS20C and the Bosch CS10.

Features & Benefits

You can read our roundup of the best compact circular saws and 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 BDCCS20C is cordless and runs on 20 V batteries.

The CS10 motor spins at 5600 rpm. Don’t get too caught up in these numbers, since the manufacturers measure them under ideal conditions, meaning they don’t have a meaningful impact on the saw’s real-world capacity 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

Both products have a 5/8” arbor. The BDCCS20C accepts 5 1/2” diameter blades. The CS10 takes 7 1/4” diameter blades. Most 8-to-10” blades have a 5/8” arbor hole, so this size of arbor maximizes blade compatibility.

The BDCCS20C can bevel the blade up to 45°, will cut up to 1 11/16” at 90°, and can cut up to 1 3/8” deep at an angle of 45°. The CS10 can bevel its 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°.

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 Black+Decker has the blade on the left side of the body. The Bosch has the blade on the right 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.
