Let’s take a look at these two circular saws: the DeWalt DCS571B and the Dremel US40-04.

Features & Benefits

Power & Motor

The US40-04 is corded, runs on 120 V, and draws 7.5 amps. Standard U.S. residential circuits are 120 V, 15 A, which will support the.

The DCS571B is cordless and runs on 20 V batteries.

The DCS571B motor spins at 4500 rpm and the US40-04 motor spins at 13000 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 US40-04 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 DCS571B accepts 4 1/2” diameter blades and has a 3/8” arbor. The US40-04 takes 4” diameter blades.

The DCS571B can bevel its blade up to 45° and can cut up to 1 9/16” at a 90° angle. The US40-04 can bevel up to 0° and can cut up to 3/4” deep at a 90° 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 DeWalt has stops at 90 Degrees.

Both products 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.
