Comparing DEWALT Angle Grinder Specs

Power and speed

Edge: DEWALT 20V MAX XR 5-Inch Brushless Angle Grinder

The DEWALT 20V MAX XR 5-Inch Brushless Angle Grinder lists a no-load speed of 9,000 RPM. It also claims up to 1,590 MWO for tough jobs. The DEWALT 20V MAX 4-1/2-Inch Brushless Paddle Grinder does not list specific RPM or MWO figures in the provided data. Higher RPM generally means faster cutting or grinding. The XR model’s stated 9,000 RPM gives you a clear performance metric to compare against other tools. You get more specific power data with the XR model.

Wheel compatibility

Edge: DEWALT 20V MAX XR 5-Inch Brushless Angle Grinder

The DEWALT 20V MAX XR 5-Inch Brushless Angle Grinder accepts wheel diameters from 4-1/2 inches to 5 inches. This wider range lets you use larger discs for more aggressive material removal. The DEWALT 20V MAX 4-1/2-Inch Brushless Paddle Grinder is listed with a 4-1/2 inch wheel diameter. It does not mention 5-inch compatibility in the specs. If you frequently use 5-inch discs, the XR model offers that flexibility. The standard model is limited to the smaller size.

Switch type

Edge: DEWALT 20V MAX 4-1/2-Inch Brushless Paddle Grinder

The DEWALT 20V MAX 4-1/2-Inch Brushless Paddle Grinder features a paddle switch. This two-stage trigger requires two actions to activate the tool. Paddle switches often allow for easier one-handed operation in tight spaces. The DEWALT 20V MAX XR 5-Inch Brushless Angle Grinder does not specify its switch type in the provided attributes. You cannot confirm if it uses a paddle or a traditional trigger. For precise control via a paddle mechanism, the first model is the clear choice based on the data.

Safety features

Edge: Tie

The DEWALT 20V MAX 4-1/2-Inch Brushless Paddle Grinder includes a Kickback Brake. This system engages when a pinch or stall is sensed, stopping the wheel quickly. It also has E-Switch Protection for no-volt release. The DEWALT 20V MAX XR 5-Inch Brushless Angle Grinder features an anti-rotation system. This shuts down the tool if excessive rotational motion is detected. Both offer advanced safety. The first stops the wheel directly; the second prevents dangerous tool rotation.

Weight and size

Edge: DEWALT 20V MAX 4-1/2-Inch Brushless Paddle Grinder

The DEWALT 20V MAX 4-1/2-Inch Brushless Paddle Grinder weighs 3.75 pounds. Its dimensions are 12.2 inches long, 4.7 inches wide, and 6 inches high. The DEWALT 20V MAX XR 5-Inch Brushless Angle Grinder weighs 4.59 pounds. It measures 13.1 inches long, 6.2 inches wide, and 4.9 inches high. The standard model is lighter and slightly more compact. This may reduce fatigue during extended overhead work. The XR model is heavier due to its larger build and power.
