DEWALT vs Makita: Angle Grinders Compared by Specs

Key differences

Which one should you choose?

Voltage, Safety, and Size Specs

Voltage platform

Edge: DEWALT 20V MAX 4-1/2-Inch Brushless Paddle Grinder

DEWALT uses its 20V MAX system, while Makita relies on the 18V LXT platform. Higher voltage generally supports more robust power delivery under load. You might prefer the DEWALT 20V MAX for heavier cutting tasks, as the extra two volts can help maintain torque. Makita’s 18V system is still highly capable for most general grinding and cutting jobs. The choice depends on which battery ecosystem you already own. If you are starting fresh, consider which brand offers better long-term value for your specific needs. Both systems are reliable, but the voltage difference is a key factor in performance expectations.

Wheel compatibility

Edge: Makita 18V Brushless 4-1/2 to 5-Inch Grinder

The Makita XAG04Z accepts both 4-1/2 inch and 5-inch wheels, offering more flexibility for different cutting and grinding applications. DEWALT is limited to 4-1/2 inch wheels only. If you frequently switch between smaller and larger discs, the Makita’s dual compatibility is a clear advantage. You can use larger 5-inch wheels for faster material removal on bigger projects. The DEWALT is strictly for smaller discs, which limits its scope for heavier duty work. For users who need versatility in wheel size, the Makita provides a broader range of options without needing a different tool.

Braking system

Edge: DEWALT 20V MAX 4-1/2-Inch Brushless Paddle Grinder

DEWALT features a Kickback Brake that engages when a bind-up is sensed, stopping the wheel in two seconds or less. Makita uses Active Feedback-Sensing Technology (AFT) to turn the motor off if rotation stops suddenly. Both systems prioritize safety by reacting to kickback events. DEWALT’s brake is designed to quickly stop the wheel to reduce movement, while Makita cuts power to prevent injury. The DEWALT system also includes E-Switch Protection for no-volt release safety. Both tools offer excellent braking, but DEWALT’s specific two-second stop time is a notable metric for rapid response.

Weight and size

Edge: Tie

The DEWALT model weighs 3.75 pounds and measures 12.2 inches in length. Makita’s dimensions are listed as 8.4 inches long, 4.5 inches wide, and 5.5 inches high, but weight is not provided in the data. Assuming similar construction, the DEWALT’s longer length may affect balance. You should consider how the tool feels in your hand during extended use. The Makita’s shorter length might offer better maneuverability in tight spaces. Without exact weight data for Makita, you cannot make a precise comparison on portability. Check the manufacturer’s site for the Makita’s weight to complete this assessment.

Switch type

Edge: DEWALT 20V MAX 4-1/2-Inch Brushless Paddle Grinder

DEWALT uses a paddle switch with a two-stage trigger that requires two actions to activate. This design prevents accidental startup. Makita’s switch type is not specified in the provided data. You might prefer the DEWALT’s paddle switch for better control and safety, especially in dusty or wet environments. The two-stage activation adds a layer of security against unintended operation. If Makita uses a similar safety mechanism, it would be a tie. However, without that data, DEWALT’s explicit safety features give it the edge in terms of known user protection mechanisms.

Motor efficiency

Edge: Makita 18V Brushless 4-1/2 to 5-Inch Grinder

Both tools feature brushless motors, which eliminate carbon brushes for cooler operation and longer life. Makita highlights that its brushless motor optimizes battery energy use for up to 50% longer run time per charge. DEWALT also uses a brushless motor but does not specify run time improvements. The automatic speed change technology in Makita adjusts torque and RPM for optimum performance. This electronic control can enhance efficiency during varying loads. If run time is a priority, Makita’s claimed efficiency boost is a significant advantage for extended work sessions without frequent recharging.

Choose Your Angle Grinder Based on Specs

Users needing quick wheel stop safety

Our pick: DEWALT 20V MAX 4-1/2-Inch Brushless Paddle Grinder

The DEWALT model features a Kickback Brake that engages when a pinch or bind-up event is sensed. It stops the wheel in 2 seconds or less on average. This electronic brake reduces movement and shuts the tool off quickly, offering enhanced control during sudden stops compared to standard models.

Those wanting variable speed for precision

Our pick: Makita 18V Brushless 4-1/2 to 5-Inch Grinder

Makita includes automatic speed change technology that adjusts speed and torque during operation. This ensures optimum performance for different tasks. The brushless motor matches torque and RPM to changing demands, allowing for better control on delicate materials or varied cutting requirements without manual adjustment.

Buyers preferring paddle switch operation

Our pick: DEWALT 20V MAX 4-1/2-Inch Brushless Paddle Grinder

The DEWALT grinder utilizes a paddle switch with a two-stage trigger requiring two actions to activate. This design often provides better control for some users. It also includes E-Switch Protection, ensuring the tool restarts only after the trigger is cycled off and on following a power outage.

Users needing larger disc compatibility

Our pick: Makita 18V Brushless 4-1/2 to 5-Inch Grinder

The Makita tool supports both 4-1/2 inch and 5-inch wheel diameters. This versatility allows you to use larger discs for more aggressive cutting or grinding tasks. The 5/8 inch - 11 UNC spindle thread accommodates a wider range of standard abrasive wheels and cutting discs.
