SKU : WOR-TOO-158
The DEWALT DCG416B FLEXVOLT ADVANTAGE 20V MAX brushless angle grinder (tool only) puts a serious punch in your 4-1/2 to 5-inch grinding and cutting work. When paired with a DCB606 FLEXVOLT battery, this tool can produce up to 54% more power than with a standard DEWALT 20V MAX battery, giving you the grunt you need for metal, masonry, and concrete. It's a natural fit for electricians, plumbers, steel fitters, and serious DIYers who already own DEWALT 20V MAX or FLEXVOLT batteries.
The DCG416B delivers 1,550 max watts out and up to 9,000 rpm, so it handles rapid stock removal without bogging down. The brushless motor also improves runtime and durability compared to brushed designs. This grinder is part of DEWALT's PERFORM & PROTECT line, which means you get the Kickback Brake, E-CLUTCH, and E-Switch Protection to help you stay in control.
Kickback Brake engages with maximum force to stop the wheel and shut down the grinder quickly when a bind-up occurs. E-CLUTCH cuts motor power in under a tenth of a second when a pinch or stall is detected. Together, they reduce the risk and give you more confidence on tough cuts.
The DCG416B accepts both 4-1/2-inch and 5-inch grinding wheels. To use a 5-inch wheel, install the correct 5-inch guard from DEWALT so the wheel is properly covered. Always match the guard to the wheel diameter and verify the wheel's maximum RPM rating is above the grinder's no-load speed. This setup lets you take on larger cutting jobs while keeping the guard in place for protection.
The chip pocket accepts the optional DEWALT Tool Connect Chip (DCE042), so you can track this grinder with the Tool Connect Site Manager app. That's a practical way to keep tabs on your tools from your phone or tablet.
Battery and charger are sold separately, so this kit works best if you already have a compatible DEWALT 20V MAX or FLEXVOLT battery system.
Up to 54% more power: Pair with a DCB606 FLEXVOLT battery for a major boost over standard 20V MAX packs.
Kickback Brake stops the wheel and shuts the grinder down quickly when the wheel binds.
E-CLUTCH cuts motor power in under a tenth of a second on a pinch/stall.
Accepts 4-1/2 and 5-inch wheels with the correct guard, so you can match the tool to the job.

If you're planning to use 5-inch wheels with the DCG416B, the most important change is the guard. The grinder's adjustable guard is designed to match the wheel diameter, and switching to a 5-inch guard ensures proper coverage while maintaining maneuverability. Before grinding, always check the wheel's rated RPM against the grinder's 9,000 rpm max to avoid over-speed.
FLEXVOLT ADVANTAGE tools accept both 20V MAX and FLEXVOLT batteries. When you install a FLEXVOLT battery like the DCB606, the tool automatically draws extra power for higher output. That means the DCG416B can cut faster and handle heavier material without needing a cord or a dedicated 60V grinder.
The grinder is compatible with all DEWALT 20V MAX and FLEXVOLT batteries. For best runtime and power, use a 6.0 Ah FLEXVOLT battery. If you're already in the DEWALT 20V MAX system, this tool-only grinder fits easily into your existing kit without buying a new battery platform.











Powerful and safe.
This grinder is strong and the kickback brake works. It's easy to handle. I highly recommend it.
I'm a metalworker and this grinder has changed the game. The FLEXVOLT ADVANTAGE really does deliver more power when using FLEXVOLT batteries. The Kickback Brake and E-CLUTCH give me peace of mind. I've had kickbacks before, and this stops the wheel almost instantly. The tool is well balanced and the handle is comfortable. It's a bit heavy, but that's the trade-off for power. The guard adjustment is easy. I use it almost every day and it hasn't let me down.
I used this to cut rebar for a garden project. It cut through easily. The safety features are reassuring. I'm glad I bought it.
It has plenty of power, but it drains batteries fast. With a 5Ah battery, I get about 20 minutes of continuous cutting. The safety features are great. Overall, it's a good grinder.
I've used corded grinders for years. This cordless one is just as powerful. The brake is a lifesaver. The balance is perfect. Highly recommended.
This grinder is awesome. It's got great power. The safety brake is a big plus. Love it.
I use it for metal fabrication. It works flawlessly. The E-CLUTCH prevents wheel grabs. It's a professional-grade tool.
It's powerful and easy to use. The kickback brake is a great feature. The only downside is that it's heavy to hold for long periods. But it's worth it.
I've used other grinders. This one is the best. The safety features are important to me. It cuts through steel easily. I recommend it.
It's a bit heavy for me, but it does the job. My grandson uses it more. The safety features are good to have. It's well made.
