Key Features

Corded-Level Output

The 13 amp motor equivalent and 2,300 max watts out give this cordless angle grinder the kind of output you want for heavy grinding and cutting without dragging a cord around the job.

Fast Wheel Stop

When you release the trigger, the brake can stop a standard 4-1/2 inch grinding wheel in about 1.5 seconds. That cuts down waiting between moves and helps the tool feel more controlled.

Built-In Protection

Kickback Brake and E-CLUTCH are there for the ugly moments: pinch, stall, and bind-up. Instead of letting the grinder keep twisting, the electronics react fast to shut things down.

Overview

The DeWALT DCG418B Flexvolt 60V MAX Brushless 4-1/2 in. – 6 in. Cordless Grinder With Kickback Brake is a cordless angle grinder built for heavy grinding, cutting, and metalworking where corded power is useful but cord freedom matters more. This is a cordless angle grinder designed for grinding and cutting metal with 4-1/2 inch to 6 inch wheels. Model Number: DCG418B. It is sold as a tool only, so batteries and charger are sold separately.

What makes this grinder matter is the output. DeWALT rates it at a 13 amp motor equivalent with up to 2,300 max watts out, and it runs at 9,000 RPM no-load speed for applications with 6 inch grinder wheels. In plain jobsite terms, that means it is aimed at real stock removal and cutting work, not just light cleanup. If you are knocking down welds, prepping steel, cutting pipe, trimming angle iron, or working through general fabrication tasks, those numbers tell you this tool is meant to stay productive under load.

The wheel range is another big deal. A lot of cordless grinders get bought for one narrow job, then run out of room when the work changes. The DCG418B covers both 4-1/2 inch and 6 inch setups, which gives you more flexibility between tighter work and broader, more aggressive grinding or cutting applications. DeWALT includes both a 4-1/2 inch Type 27 guard and a 6 inch Type 27 guard in the box, so you are not chasing basic hardware before the tool can go to work.

DeWALT also put the emphasis where it should be for a grinder this powerful: control when things go wrong. The brake engages when the trigger is released, with stopping speeds of 1.5 seconds when using a standard 4-1/2 inch x 1/4 inch bonded abrasive wheel, non-hubbed. On top of that, the Kickback Brake is designed to react during a pinch, stall, or bind-up event by applying maximum braking force, reducing grinder movement, and shutting the tool off. E-CLUTCH adds another layer by activating in less than a tenth of a second when a pinch or stall is detected. That combination is not fluff. On a high-output grinder, fast shutdown matters.

From a design standpoint, this is a brushless grinder built around DeWALT’s 60V MAX FLEXVOLT platform. Brushless motor design generally matters most in tools like this because it helps the grinder stay efficient and keep power delivery consistent under demanding use. The side handle, wrench, flanges, and spindle lock setup are exactly the kind of basics you want on a pro-grade grinder: simple, familiar, and jobsite friendly. The spindle thread is 5/8 inch – 11 inch, which is the standard most users expect when sourcing wheels and accessories for this class of angle grinder.

System fit is straightforward. This grinder uses the DeWALT 60V MAX FLEXVOLT battery platform and runs as a cordless battery-powered tool. If you are already invested in FLEXVOLT for saws, outdoor power equipment, or other heavy-draw tools, the DCG418B drops into that lineup cleanly. If you are not already on the platform, factor that into the buy, because this is a bare tool and does not include a battery or charger.

DeWALT states this model delivers up to 30% more power than the DCG414 grinder when comparing the specified battery setups. That makes the DCG418B a better fit for users who have already outgrown smaller cordless grinders and want something closer to corded behavior for fabrication, steel work, mechanical trades, and general construction punch-list work involving metal. It is not overkill if the grinder comes out daily. It is the right call when a lighter-duty cordless unit starts feeling like the bottleneck.

Who should buy it? Metalworkers, welders, ironworkers, mechanical contractors, facility maintenance crews, and serious remodelers who need a cordless grinder that can actually handle demanding cutting and grinding. If your work is occasional and light, a smaller grinder may be enough. If you want one cordless DeWALT grinder that covers a broad range of metal tasks with better safety response and real output, this is the one that makes the most sense.

Control the Grinder When the Cut Gets Ugly

High-power grinders are useful right up until the wheel binds or the tool twists in your hands. This model is built to react faster when that happens, which is exactly what you want on a serious metalworking grinder.

• Kickback Brake engages during pinch, stall, or bind-up events to quickly stop the wheel, reduce tool movement, and shut the grinder off
• E-CLUTCH activates in less than a tenth of a second when a pinch or stall is detected
• Trigger-release brake can stop a standard 4-1/2 inch grinding wheel in about 1.5 seconds

One Cordless Grinder for 4-1/2 Inch to 6 Inch Work
