Price Comparison
The DEWALT FLEXVOLT ADVANTAGE 20V MAX* Angle Grinder is priced at $144.50, while the Makita 9557PBX1 Cut-Off/Angle Grinder is available for $109.00. This makes the Makita about 17% cheaper than the DEWALT. The price difference may appeal to budget-conscious buyers, especially those who need a reliable tool without the premium features that come with the DEWALT model. However, it’s essential to consider what each grinder offers for its price, as the DEWALT model also boasts advanced technology that could justify its higher cost for some users.
Power and Performance
The DEWALT FLEXVOLT ADVANTAGE Grinder delivers up to 54% more power when paired with FLEXVOLT batteries compared to traditional 20V MAX batteries, producing a maximum output of 1,550 watts and a speed of 9,000 RPM. In contrast, the Makita 9557PBX1 features a 7.5 AMP motor that achieves a higher speed of 11,000 RPM. This means that while the DEWALT grinder offers enhanced power with specific battery combinations, the Makita provides a higher RPM at a consistent power level, making it potentially more effective for various grinding tasks.
Design and Ergonomics
When it comes to design, the Makita 9557PBX1 weighs only 4.5 pounds and features a small diameter barrel grip for added comfort during extended use. The DEWALT grinder, while heavier, is designed with an E-CLUTCH system that shuts down the motor in under a tenth of a second during a pinch or stall. This feature enhances safety, but the comfort offered by the Makita might make it preferable for users who prioritize ease of handling and prolonged usage.
Durability and Construction
Both models are built with durability in mind, but they approach it differently. The Makita 9557PBX1 incorporates labyrinth construction to seal and protect its motor and bearings from dust and debris, which contributes to its longevity. The DEWALT grinder also emphasizes protection with its Kickback Brake and E-CLUTCH system, designed to prevent damage during bind-ups. While both tools are sturdy, the methods of construction and protective features differ, appealing to different user needs in terms of longevity and reliability.
Safety Features
The DEWALT FLEXVOLT ADVANTAGE Grinder includes several advanced safety features, such as the Kickback Brake, which engages with maximum force to stop the wheel quickly, and the E-Switch Protection, ensuring the grinder does not restart unexpectedly after a power outage. On the other hand, the Makita 9557PBX1 offers a lock-on/off feature for continuous operation, which may be beneficial for users who need to maintain control during extended tasks. While both grinders incorporate safety measures, the DEWALT model has more sophisticated options that might enhance user safety in demanding situations.
Included Accessories
The Makita 9557PBX1 comes as a kit that includes not only the grinder but also five grinding wheels, a diamond blade, a metal tool case, and a cut-off and grinding wheel guard. This makes it a comprehensive package for those starting out or needing a full setup right away. Conversely, the DEWALT FLEXVOLT ADVANTAGE is sold as a tool only, meaning users will need to purchase batteries and chargers separately. This difference in included accessories can significantly impact the overall value of each product for different buyers.
Brand Reputation
Both DEWALT and Makita have strong reputations in the power tool industry. DEWALT's angle grinder holds a sales rank of 14,755, indicating a solid market presence and popularity among consumers. Makita's grinder, however, has a slightly lower sales rank of 31,753, which may suggest it is less favored in comparison. This difference in sales rank could influence consumer confidence, with some users preferring the more popular DEWALT based on its higher visibility and reviews.
Which should you buy?
Choosing between the DEWALT FLEXVOLT ADVANTAGE 20V MAX* Angle Grinder and the Makita 9557PBX1 Cut-Off/Angle Grinder ultimately depends on your specific needs and budget. If you prioritize advanced safety features, superior power with the right battery, and are willing to pay a premium for these, the DEWALT is a strong choice. However, if you are looking for a more affordable option that still delivers high RPM and comes with a comprehensive accessory kit, the Makita could be the better fit. Each tool has its strengths, so consider your typical projects and preferences before making a decision.
