Rockwell RK3440K vs. Rockwell RK3441K

Let’s compare these two Rockwell circular saws: the Rockwell RK3440K and the Rockwell RK3441K.

Features & Benefits

You can read our roundup of the best compact circular saws.

Power & Motor

Both products are corded and run on 120 V. The RK3440K draws 4 amps. The RK3441K draws 5 amps. Standard U.S. residential circuits are 120 V, 15 A, which will support either of the circular saws.

Both saws have motors that produce 3500 rpm. But don’t pay too much attention to these numbers, because the manufacturers measure them under no-load conditions, and they don’t have a useful impact on the saw’s real-world ability to handle different material.

The RK3440K has a direct motor. The RK3441K has 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 RK3440K takes 3 3/8” diameter saw blades and has a 19/32” arbor. The RK3441K accepts 4 1/2” diameter blades and has a 3/8” arbor.

The RK3440K can bevel the blade up to 0° and will cut up to 1 1/16” at 90°. The RK3441K can bevel up to 45°, can cut up to 1 11/16” deep at an angle of 90°, and is able to cut up to 1 1/8” 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.

Both products have the blade mounted 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.
