DEWALT FLEXVOLT ADVANTAGE 20V MAX Angle Grinder (DCG416B) | 4-1/2 to 5 in, Tool Only

Overview

Meet the DEWALT FLEXVOLT ADVANTAGE 20V MAX Angle Grinder, a compact yet rugged tool built for demanding sites. Designed to maximize on-battery performance, this model can deliver up to 54% more power when paired with FLEXVOLT batteries, compared to standard 20V MAX setups. Its brushless motor delivers up to 1,550 max watts and reaches speeds up to 9,000 RPM, giving you the speed to cut, grind, and shape with efficiency on metal, masonry, and composite materials.

Power, speed, and control

Thanks to a brushless design, the grinder runs cooler and more efficiently under load, helping you sustain performance across long tasks. The 4-1/2" to 5" grinding disc capacity provides versatility for rough material removal as well as finishing work. The tool is designed to work with all DEWALT 20V MAX* and FLEXVOLT batteries, so you can scale power to the job without overhauling your kit.

Safety and smart protection

Safety is built into the PERFORM & PROTECT line with notable features designed to prevent accidental wheel exposure and control mishaps on busy jobsites. The Kickback Brake engages with maximum braking force to stop the wheel quickly if a bind-up occurs. The E-CLUTCH system shuts the motor down in under a tenth of a second when a pinch or stall is detected, reducing wear and potential damage. E-Switch Protection requires cycling the trigger off and on after unexpected shutdowns to restart, adding a layer of reliability in demanding conditions.

Connectivity and asset management

For teams embracing smart tools, Tool Connect Chip Ready expands site management options. When paired with the appropriate Chip (sold separately), the grinder can be tracked and managed via the Tool Connect Site Manager app, helping you monitor usage, maintenance, and location from the office or truck.

Real-world use cases

On worksites ranging from metal fabrication to concrete prep, this grinder handles edge grinding, rust removal, deburring, and surface finishing with consistent performance. Its balanced design and paddle switch offer comfortable handling in confined spaces, giving you a steady, controlled grip during extended sessions.
