Bosch CS10 vs. Skilsaw SPT77WML-01

We’ll take a look at these two circular saws: the Bosch CS10 and the Skilsaw SPT77WML-01.

Features & Benefits

For more information, read more in our roundup of the best full-size circular saws.

Power & Motor

Both products are corded, require 120 V, and draw 15 amps. In the U.S., standard residential circuits are 120 V, 15 A, which will support either of the circular saws.

The CS10 motor produces 5600 rpm and the SPT77WML-01 motor produces 5300 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.

The CS10 has a direct-drive motor. The SPT77WML-01 has a worm-drive motor. Direct-drive motors are usually lighter than other styles, but their side mounting makes the saw a little harder to control. Worm-drive motors are longer and heavier, but often more powerful and easier to control due to the weight being more centered.

Blades & Capacity

Both saws accept 7 1/4” diameter saw blades and have a 5/8” arbor. Most 8-to-10” blades have a 5/8” arbor hole, so this size of arbor provides a lot of choices.

The CS10 can bevel its blade up to 56°, can cut up to 2 7/16” at 90°, and will cut up to 1 7/8” deep at a 45° angle. The SPT77WML-01 can bevel up to 53°, is able to cut up to 2 3/8” at an angle of 90°, and can cut up to 1 15/16” deep at 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 Skilsaw has stops at 45°.

The Bosch has the blade on the right side of the unit. The Skilsaw has the blade on the left side of the body. 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.
