Let’s take a look at these two circular saws: the Black+Decker BDCCS20C and the Rockwell RK3440K.

Features & Benefits

Power & Motor

The RK3440K is corded, runs on 120 V, and draws 4 amps. In the U.S., standard residential circuits are 120 V, 15 A, which will support the.

The BDCCS20C is cordless and runs on 20 V batteries.

The RK3440K motor spins at 3500 rpm. Don’t get too caught up in these numbers, since the manufacturers measure them under ideal conditions, meaning they don’t have a direct impact on the saw’s real-world capacity to handle different material.

The BDCCS20C has a direct-drive motor. The RK3440K has a direct 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 BDCCS20C takes 5 1/2” diameter blades and has a 5/8” arbor. The RK3440K accepts 3 3/8” diameter blades and has a 19/32” arbor. Most 8-to-10” blades have a 5/8” arbor hole, so this size of arbor gives you a lot of options.

The BDCCS20C can bevel the blade up to 45°, can cut up to 1 11/16” deep at 90°, and will cut up to 1 3/8” at a 45° angle. The RK3440K can bevel up to 0° and is able to cut up to 1 1/16” deep at an angle of 90°.

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.

Both saws have the blade 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.
