Its compact design, weighing only 4.5 lbs, makes it comfortable to handle for extended periods.

Performance Comparison
When it comes to performance, the DEWALT 20V MAX* Angle Grinder excels with its brushless motor and safety features. The brushless motor not only extends the tool's lifespan but also provides consistent power without the need for maintenance. The DEWALT's kickback brake is a significant feature that enhances safety by stopping the wheel quickly during unexpected incidents.
On the other hand, the Makita 9557NB’s 7.5 AMP motor and 11,000 RPM speed offer considerable power for grinding tasks. While it lacks some of the advanced safety features of the DEWALT, its robust construction and protective varnish help ensure durability. This makes the Makita a solid choice for those who prioritize raw power in their tools.
Safety Features
Safety is a critical aspect when comparing these two angle grinders. The DEWALT 20V MAX* Angle Grinder is equipped with a kickback brake that engages when a stall or bind-up event occurs, stopping the wheel in a mere 2 seconds. This feature aims to minimize the risk of accidents and enhance user control during operation.
Conversely, the Makita 9557NB offers safety through its protective varnish and labyrinth construction that seals the motor and bearings from dust and debris. Although it doesn't feature a kickback brake, the overall design emphasizes protecting the internal components, contributing to user safety in less direct ways.
Portability and Convenience
Portability is a strong point for the DEWALT 20V MAX* Angle Grinder, as it is cordless, allowing for hassle-free movement across job sites. This feature is particularly beneficial for professionals who need to work in various locations without the constraints of power cords. However, keep in mind that the battery and charger are sold separately, which adds to the overall cost.
In contrast, the Makita 9557NB operates on a standard AC power source, which means it will always be ready to use as long as you have access to electricity. Its lightweight design also makes it easy to carry around, making it suitable for those who need a reliable tool that can be quickly deployed.
Price Comparison
A significant difference between the two grinders is their pricing. The DEWALT 20V MAX* Angle Grinder is priced at $249.00, while the Makita 9557NB is priced at $84.01. This makes the Makita about 66% cheaper than the DEWALT, which may appeal to budget-conscious consumers or those who do not require the advanced features of a higher-priced model.
While the DEWALT offers additional safety and performance features, the Makita provides excellent value for money, especially for occasional users or DIY enthusiasts who need a reliable grinder without breaking the bank.
Customer Rankings
In terms of customer popularity, the DEWALT 20V MAX* Angle Grinder has a sales rank of 1826, which indicates a strong presence in the market. Its advanced features and reputation for quality contribute to its favor among professionals. On the other hand, the Makita 9557NB has a sales rank of 74761, suggesting that while it is a solid choice, it may not be as widely recognized as the DEWALT among serious users.
This difference in ranking could influence potential buyers based on brand reputation, perceived quality, and user experiences shared through reviews.
Which should you buy?
Choosing between the DEWALT 20V MAX* Angle Grinder and the Makita 9557NB ultimately depends on your specific needs and budget. If you prioritize safety features, advanced technology, and a longer motor life, the DEWALT is the superior choice, albeit at a higher price point. However, if you seek an affordable, reliable grinder that offers solid performance for general tasks, the Makita is an excellent option that won’t strain your wallet. Consider how you plan to use the grinder and whether the additional features of the DEWALT justify its price for your particular situation.
