Grinder Specs Compared Side by Side
Wheel compatibility
The DEWALT 20V MAX 4-1/2-Inch Brushless Paddle Grinder is designed specifically for 4-1/2 inch wheels. Its model number is DCG413B. This tool offers a fixed wheel size. In contrast, the DEWALT 4-1/2 to 5-Inch Paddle Switch Angle Grinder supports a broader range. It accepts both 4-1/2 inch and 5 inch discs. This flexibility allows you to use larger cutting or grinding wheels without needing a separate tool. If you frequently switch between smaller and larger abrasive sizes, the wider compatibility of the second model provides a clear practical advantage for your workflow.
Power output
Both tools utilize brushless motors for efficiency. However, the DEWALT 4-1/2 to 5-Inch Paddle Switch Angle Grinder highlights a specific performance metric. It delivers up to 54% more power when paired with FLEXVOLT batteries. The DEWALT 20V MAX 4-1/2-Inch Brushless Paddle Grinder does not list this specific power increase percentage in its specifications. It operates on standard 20V MAX power. If you require maximum torque and cutting speed for demanding materials, the potential for higher output with compatible batteries makes the second option superior in raw capability.
Motor protection
Safety features differ slightly between the two models. The DEWALT 20V MAX 4-1/2-Inch Brushless Paddle Grinder includes a standard kickback brake that stops the wheel in two seconds or less. It also features E-Switch Protection to prevent unexpected restarts. The DEWALT 4-1/2 to 5-Inch Paddle Switch Angle Grinder adds an E-CLUTCH system. This feature shuts down the motor in under a tenth of a second when a pinch or stall is detected. This faster response time offers enhanced protection against sudden binding events compared to the standard brake timing.
Battery compatibility
Both grinders are bare tools and do not include batteries. They both run on 20V MAX power sources. The DEWALT 20V MAX 4-1/2-Inch Brushless Paddle Grinder is compatible with standard 20V MAX batteries. The DEWALT 4-1/2 to 5-Inch Paddle Switch Angle Grinder explicitly states compatibility with all DEWALT 20V MAX and FLEXVOLT batteries. This means you can use the larger, more powerful FLEXVOLT cells with the second tool to gain extra runtime and power. The first tool does not mention FLEXVOLT support, limiting its battery options to the standard 20V MAX line.
Physical dimensions
Size and weight vary between the two grinders. The DEWALT 20V MAX 4-1/2-Inch Brushless Paddle Grinder measures 12.2 inches in length and weighs 3.75 pounds. It has a width of 4.7 inches. The DEWALT 4-1/2 to 5-Inch Paddle Switch Angle Grinder is longer at 13.1 inches but significantly lighter at 1 pound. Its width is listed as 1 inch. The lighter weight of the second model may reduce fatigue during extended overhead work. However, the first model is more compact in overall length, which might fit better in tighter spaces.
Which grinder fits your workflow best
You need versatile wheel sizes for different tasks
The FLEXVOLT Advantage model accepts both 4-1/2 inch and 5-inch wheels. This flexibility allows you to handle larger cutting or grinding jobs without switching tools. You also get up to 54% more power when using FLEXVOLT batteries, providing extra torque for demanding applications compared to standard 20V MAX units.
You prioritize compact size and lighter weight
This 4-1/2 inch grinder weighs 3.75 pounds and measures 12.2 inches in length. While heavier than the FLEXVOLT option, its fixed 4-1/2 inch wheel size keeps the tool profile consistent. The brushless motor requires no brush changes, ensuring long-term reliability for standard angle grinding duties without the complexity of variable wheel compatibility.
You want advanced asset management capabilities
This model features a Tool Connect Chip pocket that accepts the DCE042 chip. This allows you to track the tool using the Tool Connect Site Manager app. If you manage multiple tools on a jobsite, this integration helps with asset management. The standard 20V MAX grinder does not offer this digital tracking feature.
You prefer a dedicated 4-1/2 inch tool
If you only use 4-1/2 inch wheels, this dedicated grinder is a straightforward choice. It features E-Switch Protection to prevent unexpected restarts after power outages. The two-stage paddle switch requires two actions to activate, which can enhance control and safety during precise grinding work compared to single-action triggers found on some other models.
