Variable Speed Control
One of the standout features of the Makita 18V Angle Grinder is its variable speed control dial. Users can adjust the speed between 3,000 and 8,500 RPM to match the application. This flexibility allows for precision in tasks ranging from grinding and cutting to polishing and sanding.
Automatic Speed Change Technology
Makita’s Automatic Speed Change technology adjusts speed and torque during operation for optimal performance. This feature ensures that the grinder maintains its power even under heavy load, providing a smoother and more efficient user experience.
Compact and Ergonomic Design
The DGA463 is designed with user comfort in mind. It features a compact design with an overall length of only 14-1/4 inches and weighs just 5.5 pounds (with battery). The slim barrel grip and ergonomic handle reduce user fatigue, making it easier to handle for extended periods.
Anti-Restart Function
Safety is a priority with the Makita 18V Angle Grinder. The anti-restart function prevents accidental start-up, ensuring that the tool does not turn on unexpectedly after a power interruption.
Soft Start Feature
The soft start feature gradually increases the speed of the grinder, reducing the initial shock and ensuring a smoother start-up. This feature not only enhances user control but also extends the tool’s lifespan by reducing stress on the motor.
Electric Brake
For added safety and convenience, the DGA463 is equipped with an electric brake that stops the wheel quickly when the trigger is released. This feature is particularly useful in preventing accidents and improving workflow efficiency.

Disadvantages of the Makita 18V Angle Grinder
Initial Cost
One of the main disadvantages of the Makita 18V Angle Grinder is its initial cost. As a high-quality, professional-grade tool, it is priced higher than many other models on the market. However, this cost is often justified by the tool’s performance and durability.
Battery and Charger Sold Separately
The DGA463 is sold as a bare tool, meaning that the battery and charger are not included. This can add to the overall cost if you do not already own compatible Makita 18V LXT batteries and a charger.
Limited Battery Life
While the Makita 18V LXT batteries provide good run time, extended use of high-power tools like angle grinders can drain the battery relatively quickly. Users may need to have spare batteries on hand to avoid downtime.
Comparison to Similar Products on the Market
DeWalt 20V MAX XR Angle Grinder (DCG413B)
The DeWalt 20V MAX XR Angle Grinder is a comparable product in terms of features and performance. It also features a brushless motor, variable speed control, and a compact design. However, the DeWalt model operates on a 20V battery platform, which offers slightly more power but can be heavier and bulkier.
Milwaukee M18 FUEL 4-1/2″ / 5″ Grinder (2780-20)
The Milwaukee M18 FUEL Grinder is another strong competitor. It boasts a powerful brushless motor, RapidStop brake, and Redlink Plus intelligence for optimised performance. The Milwaukee grinder is known for its durability and high performance but tends to be on the higher end of the price spectrum.
Bosch GWS18V-45 18V Angle Grinder
The Bosch GWS18V-45 offers a balance of power and affordability. It features a four-brush motor design for increased performance and durability. However, it lacks some of the advanced features found in the Makita and DeWalt models, such as automatic speed change and anti-restart functions.
Comparison Summary
While all these models offer high-quality performance, the Makita 18V Angle Grinder stands out for its combination of advanced features, safety enhancements, and ergonomic design. The DeWalt and Milwaukee models offer slightly more power due to their higher voltage batteries, but the Makita’s comprehensive feature set and efficiency make it a strong contender.
