Rockwell RK3441K vs. Worx WX439L
Shopping for a new circular saw? Compare the features of the Rockwell RK3441K and Worx WX439L and make an informed purchase!
Let’s take a look at these two circular saws: the Rockwell RK3441K and the Worx WX439L.
Features & Benefits
You can read more in our roundup of the best compact circular saws.
Power & Motor
Both products are corded and run on 120 V. The RK3441K draws 5 amps. The WX439L draws 4.5 amps. Standard U.S. residential circuits are 120 V, 15 A, which will support either of the saws.
The RK3441K motor spins at 3500 rpm and the WX439L motor spins at 4100 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.
The RK3441K has a direct-drive motor. The WX439L 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
Both circular saws accept 4 1/2” diameter blades and have a 3/8” arbor.
Both products can bevel their blades up to 45°, can cut up to 1 11/16” deep at a 90° angle, and can cut up to 1 1/8” at a 45° angle.
Both saws have 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.
Pros & Cons
Let’s take a look at some of the pluses and minuses of these products.
For the Rockwell:
Pros
- Left-mounted blade improves visibility of cut line
- Easy-to-operate trigger and safety
Cons
- Some users report that the bolt holding the blade can snap off
For the Worx:
Pros
- Slimmer handle than its predecessor is easier to grip
- Includes rip fence
- Dust port for connecting to a shop vacuum
Cons
- Rip fence is tricky to keep accurate when tightening
- Struggles to cut through full 2x products
