DEWALT FLEXVOLT ADVANTAGE 20V MAX Angle Grinder - Brushless Power

In this review the DEWALT FLEXVOLT ADVANTAGE 20V MAX angle grinder is presented as a compact cordless option for users who need portable cutting and grinding with increased power when paired with FLEXVOLT cells. The bottom line: it is best for tradespeople and serious DIYers who already own DEWALT 20V MAX or FLEXVOLT batteries and want a brushless grinder that adds safety features like Kickback Brake and E-CLUTCH. Battery and charger are sold separately, so the grinder is best evaluated as a tool-only purchase where battery choice affects overall performance.

Key Features

• FLEXVOLT Advantage: When used with a DCB606 FLEXVOLT battery the grinder can deliver up to 54% more power than with a standard 20V MAX battery, which is useful for tougher cutting and grinding tasks.
• Brushless motor: The brushless motor produces up to 1,550 max watts out and spins up to 9,000 rpm for efficient material removal and longer motor life under load.
• Kickback Brake: The Kickback Brake activates with maximum force to stop the wheel quickly and shut off the grinder if a bind-up occurs, improving operator safety.
• E-CLUTCH protection: The E-CLUTCH cuts motor power in under a tenth of a second when a pinch or stall is detected, reducing sudden torque reactions.
• Tool Connect ready: The chip pocket accepts the Tool Connect Chip for asset tracking with the Tool Connect Site Manager app, which helps manage tools on larger jobsites.
• E-Switch protection: The E-Switch requires the trigger to be cycled to restart after a power interruption, preventing unexpected restarts.

Who It's For

The grinder is aimed at professionals and dedicated DIYers who value the portability of cordless tools and already invest in the DEWALT 20V MAX or FLEXVOLT battery ecosystem. It suits light to medium fabrication, grinding, and cutting tasks, especially when paired with a high-capacity FLEXVOLT battery for peak power.

It is less well suited to users who need sustained high-power performance for heavy metal removal or prolonged concrete cutting without access to the larger FLEXVOLT battery options; some customers reported mixed results on very demanding tasks, so those needing continuous heavy-duty power should consider corded or higher-capacity battery solutions.

Pros & Cons

Pros

• Brushless motor delivers efficient power and up to 9,000 rpm for fast cutting and grinding.
• Safety systems like Kickback Brake and E-CLUTCH reduce the risk of injury during bind-ups or stalls.
• Compatibility with both 20V MAX and FLEXVOLT batteries offers flexibility across existing DEWALT batteries.
• Tool Connect chip pocket enables simple asset tracking when used with the optional chip.

Cons

• Performance depends heavily on battery choice; with smaller 20V MAX batteries it may feel underpowered for tougher jobs.
• Battery and charger sold separately, adding to the initial cost for users who do not already have compatible batteries.

Specifications

Our Verdict

The DEWALT FLEXVOLT ADVANTAGE 20V MAX angle grinder is a well-rounded cordless grinder for users invested in DEWALT batteries who want brushless efficiency and built-in safety systems.
