Skilsaw SPT77WML-01 vs. Worx WX429L

Let’s compare these two circular saws: the Skilsaw SPT77WML-01 and the Worx WX429L.

Features & Benefits

You can read our roundup of the best compact circular saws and the best full-size circular saws.

Power & Motor

Both circular saws are corded and run on 120 V. The SPT77WML-01 draws 15 amps. The WX429L draws 4 amps. Standard U.S. residential circuits are 120 V, 15 A, which will support either of the saws.

The SPT77WML-01 has a motor that spins at 5300 rpm and the WX429L has a motor that spins at 3500 rpm. You shouldn’t get too caught up in the RPM numbers, since the manufacturers test them under ideal conditions, and they don’t have a direct correlation with the saw’s real-world ability to handle various types of material.

The SPT77WML-01 has a worm-drive motor. The WX429L has a direct drive motor. Worm-drive motors are longer and heavier, but often more powerful and easier to control due to the weight being more centered.

Blades & Capacity

The SPT77WML-01 takes 7 1/4” diameter blades and has a 5/8” arbor. The WX429L accepts 4 1/2” diameter saw blades and has a 3/8” arbor. Most 8-to-10” blades have a 5/8” arbor hole, so this size arbor provides a lot of choices.

The SPT77WML-01 can bevel up to 53°, is able to cut up to 2 3/8” deep at a 90° angle, and will cut up to 1 15/16” at 45°. The WX429L can bevel the blade 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.

The Skilsaw has stops at 45°.

Both products 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.
