Bosch CS10 vs. Rockwell RK3441K

We’ll take a look at these two circular saws: the Bosch CS10 and the Rockwell RK3441K.

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 RK3441K draws 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 RK3441K motor produces 3500 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.

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 saw blades and has a 5/8” arbor. The RK3441K accepts 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 arbor maximizes blade compatibility.

The CS10 can bevel its blade up to 56°, is able to cut up to 2 7/16” deep at an angle of 90°, and can cut up to 1 7/8” at 45°. The RK3441K can bevel up to 45°, will cut up to 1 11/16” deep at a 90° angle, and is able to cut up to 1 1/8” 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 Rockwell 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.
