DEWALT FLEXVOLT ADVANTAGE 20V MAX* Angle Grinder, vs Makita 9557NB 4-1/2" Angle Grinder

Overview of the DEWALT FLEXVOLT ADVANTAGE 20V MAX* Angle Grinder

The DEWALT FLEXVOLT ADVANTAGE 20V MAX* Angle Grinder is designed for users looking for high performance and versatility. This tool features a powerful brushless motor that delivers 1,550 max watts out and a maximum speed of 9,000 RPM. In contrast, the Makita 9557NB 4-1/2" Angle Grinder, while more affordable, operates with a robust 7.5 AMP motor that reaches up to 11,000 RPM. This highlights that while the DEWALT offers advanced technology and compatibility with FLEXVOLT batteries, the Makita provides higher RPMs for potentially faster cutting and grinding tasks.

Price Comparison

The DEWALT angle grinder is priced at $144.50, while the Makita 9557NB is significantly cheaper at $84.01, making it about 42% less expensive than its DEWALT counterpart. This price difference could be a decisive factor for budget-conscious consumers or those who need a grinder for lighter tasks. Even though the DEWALT grinder offers advanced features and greater power potential, the Makita's affordability may make it a more attractive option for occasional users or those with less demanding requirements.

Power and Performance

The DEWALT grinder boasts up to 54% more power when paired with FLEXVOLT batteries, emphasizing its capability when used with the right power source. In contrast, the Makita grinder's 7.5 AMP motor is engineered for high output, delivering 11,000 RPM consistently. This allows for effective performance in various applications. However, DEWALT’s E-CLUTCH system offers enhanced protection by shutting down the motor within a tenth of a second during a bind-up, which is a critical feature for safety in high-demand situations.

Design and Ergonomics

In terms of design, the DEWALT FLEXVOLT ADVANTAGE is notable for its paddle switch and compatibility with all DEWALT 20V MAX* and FLEXVOLT batteries. This versatility is highly beneficial for users who may already own DEWALT tools. The Makita 9557NB, on the other hand, features a compact design with a small 2-1/2" diameter barrel, weighing only 4.5 lbs. This lightweight structure enhances comfort and maneuverability, making it suitable for extended use without causing fatigue.

Durability and Build Quality

The DEWALT grinder is part of the PERFORM & PROTECT product line, featuring a Kickback Brake and E-CLUTCH system designed to enhance user safety and tool longevity. Meanwhile, the Makita 9557NB incorporates protective varnish and labyrinth construction that seals the motor and bearings from dust and debris, which is crucial for maintaining the tool's performance over time. Both grinders emphasize durability, but DEWALT's advanced safety features could appeal more to professional users working in demanding environments.

Features and Technology

The DEWALT grinder includes a Tool Connect Chip pocket, allowing for asset management via the Tool Connect Site Manager app. This technology can be particularly advantageous for contractors and professionals who manage multiple tools on job sites. Conversely, the Makita grinder comes equipped with an AC/DC switch, enabling use with alternative power sources, which may be a significant advantage in various settings. While both tools offer unique features, the choice will depend on the specific needs of the user regarding technology and versatility.

User Experience and Feedback

The DEWALT FLEXVOLT ADVANTAGE has a sales rank of 14,755, indicating a solid level of popularity and acceptance among users. In comparison, the Makita 9557NB has a higher sales rank of 74,761, which may suggest that it is less favored, possibly due to its more basic feature set. User feedback typically emphasizes the DEWALT's power and safety features, while the Makita is often praised for its affordability and ease of use. This contrast in user experiences can heavily influence purchasing decisions.

Which should you buy?

Choosing between the DEWALT FLEXVOLT ADVANTAGE 20V MAX* Angle Grinder and the Makita 9557NB ultimately comes down to your specific needs and budget. If you're looking for advanced features, greater power potential with FLEXVOLT batteries, and enhanced safety systems, the DEWALT grinder may be the better option despite its higher price. However, if you are seeking a reliable, cost-effective tool for lighter tasks, the Makita offers an excellent balance of performance and affordability. Thus, your decision should reflect your typical usage and whether the advanced features of the DEWALT justify the additional cost.
