The DeWALT FLEXVOLT 60V MAX Brushless Cordless 4-1/2 in. - 6 in. Grinder with Kickback Brake delivers corded-tool power with the freedom of a cordless platform - making it a serious choice for grinding, cutting, and surface preparation on demanding job sites. Powered by a 60V MAX Lithium Ion battery system and engineered with a brushless motor producing 13 amp equivalent power and 2,300 watts out, this angle grinder handles tough material removal without being tethered to an outlet. The PERFORM and PROTECT safety architecture - including E-CLUTCH and Kickback Brake technology - helps protect the operator when unexpected pinch or stall events occur. Sold as a bare tool, battery and charger are sold separately.

Key Features

• 13 amp motor equivalent power with 2,300 UWO output - delivers corded-level performance for heavy grinding and cutting tasks, so you are not sacrificing productivity by going cordless.
• 9,000 RPM no-load speed - optimized for use with 6 in. grinder wheels, giving you fast material removal and smooth surface work across a wider range of wheel sizes.
• Kickback Brake technology - senses a pinch, stall, or bind-up event and engages the electronic brake with maximum force to quickly stop the wheel, reduce grinder movement, and shut the tool off - a critical safety layer in unpredictable conditions.
• E-CLUTCH activates in less than one-tenth of a second - when a pinch or stall is detected the motor shuts down nearly instantly, limiting the risk of injury or loss of control before the operator can react.
• Trigger brake engages when the trigger is released - stops the wheel in approximately 1.5 seconds when using a standard 4-1/2 in. x 1/4 in. bonded abrasive wheel (non-hubbed), reducing rundown time and improving site safety between uses.
• Up to 30% more power vs. the DCG414 grinder - a measurable upgrade for users already in the DeWALT 60V MAX ecosystem who need more cutting force for denser materials.
• Variable speed with trigger switch control - lets you dial in the right speed for the application, reducing the risk of gouging softer materials or overspeeding smaller wheels.
• Spindle lock and 5/8-11 UNC arbor - simplifies and speeds up wheel changes using the included wrench, and ensures compatibility with a wide range of standard grinding and cutting wheels.
• Straight handle with overload protection - provides a stable, familiar grip for extended use while the overload protection safeguards the motor from damage during sustained heavy loads.
• Accepts 4-1/2 in. and 6 in. wheels - one tool covers two common wheel sizes, reducing the number of grinders needed on the job and increasing versatility across applications.

Why This Product

• Cordless freedom at corded power levels - with 2,300 UWO and 13 amp equivalent output from the 60V MAX FLEXVOLT platform, this grinder eliminates the need for a power outlet or extension cord without sacrificing the muscle needed for heavy grinding work.
• Built-in safety systems for high-risk grinding tasks - the combination of Kickback Brake and E-CLUTCH gives operators two layers of automated protection that respond faster than human reaction time - particularly valuable when working overhead, in confined spaces, or with large-diameter wheels.
• Part of the DeWALT 60V MAX battery ecosystem - if you already own 60V MAX or FLEXVOLT batteries, this bare tool integrates directly into your existing platform, letting you expand capability without purchasing a new battery system.
• Dual-wheel-size compatibility in a single tool - by accepting both 4-1/2 in. and 6 in. type 27 wheels (guards for both sizes are included), this grinder covers a broader range of grinding, cutting, and blending tasks than a single-size model would allow.

Frequently Asked Questions

Does this grinder come with a battery and charger?

No. The DCG418B is a bare tool - it does not include a battery or charger. A compatible 60V MAX Lithium Ion battery and charger must be purchased separately.

What wheel sizes does the DCG418B support?

This grinder accepts both 4-1/2 in. and 6 in. wheels. Type 27 guards for both sizes are included in the box, so you can switch between wheel diameters without purchasing additional accessories.

What is the difference between the Kickback Brake and the E-CLUTCH on this grinder?

These are two distinct safety systems that work together. The Kickback Brake engages when a pinch, stall, or bind-up event is sensed - applying the electronic brake with maximum force to stop the wheel, reduce grinder movement, and shut the tool off. The E-CLUTCH is a separate system that activates in less than one-tenth of a second when a pinch or stall is detected, immediately shutting down the motor. Both systems are part of the PERFORM and PROTECT lineup and are designed to reduce operator risk during unexpected tool events.

How fast does the wheel stop after the trigger is released?

When the trigger is released, the brake engages and stops the wheel in approximately 1.5 seconds when using a standard grinding wheel - specifically a 4-1/2 in. x 1/4 in. bonded abrasive wheel (non-hubbed). This fast stopping time reduces rundown hazards between uses.
