Overview of the Makita 9557NB and RhovixStar Brushless Angle Grinder

The Makita 9557NB is a powerful corded angle grinder, while the RhovixStar Brushless Angle Grinder is a cordless option. The Makita is priced at $84.01, whereas the RhovixStar is about 17% cheaper at $65.99. The choice between these two grinders boils down to power source preference and specific features designed for different tasks.

Performance Comparison

The performance capabilities of the Makita 9557NB are impressive, boasting a powerful 7.5 AMP motor that delivers a no-load speed of 11,000 RPM. This high output makes it suitable for heavy-duty tasks. In contrast, the RhovixStar features a brushless motor, which generally offers longer lifespan and enhanced efficiency. It operates at variable speeds up to 9,000 RPM, which provides flexibility for various applications, including sanding, polishing, and cutting. While the Makita excels in raw power, the RhovixStar's brushless motor offers longevity and versatility, making it effective for a range of tasks.

Design and Ergonomics

When it comes to design, the Makita 9557NB features a compact design with a small 2-1/2" diameter barrel, weighing only 4.5 lbs, which enhances handling comfort. Its AC/DC switch allows for use with alternative power sources. The RhovixStar also prioritizes ergonomics with an adjustable handle suitable for both left and right-handed users, designed to minimize wrist fatigue during extended use. While both grinders emphasize comfort, the Makita’s lightweight design may give it an edge for prolonged use.

Features and Usability

The Makita 9557NB is equipped with a protective zig-zag varnish that seals the armature from dust and debris, extending its lifespan. Its labyrinth construction further protects the drive gear and bearings from contamination, ensuring durability. The RhovixStar shines with its inclusion of two battery packs, providing extended runtime for outdoor or indoor use without the limitations of a power cord. It also offers four adjustable speeds, making it versatile for different cutting and polishing tasks. Users may find the battery-powered convenience of the RhovixStar appealing, especially for jobs that require mobility.

Accessories and Included Equipment

The Makita 9557NB comes with essential accessories, including a 4-1/2" grinding wheel, wheel guard, lock nut, and side handle, making it ready for use right out of the box. Conversely, the RhovixStar provides an extensive kit, including two 4.0Ah batteries, a fast charger, a handle, multiple wheels, and a wrench. This comprehensive offering could be a significant advantage for users looking for a complete toolset that allows immediate versatility in their tasks.

Portability and Convenience

The RhovixStar’s cordless design makes it inherently more portable and convenient for use in areas where access to a power source is limited. Users can move freely without being tethered to an outlet. The Makita, being corded, is less portable but compensates with consistent power delivery. Those who prioritize mobility and ease of use may favor the RhovixStar, especially for tasks like outdoor cutting or on-site work.

Cost Consideration

With a price tag of $84.01, the Makita 9557NB is positioned as a premium option in the angle grinder market. The RhovixStar, at $65.99, offers a more budget-friendly alternative, appealing to those who need a reliable tool without breaking the bank. While the Makita has a higher sales rank of 74,761 compared to the RhovixStar’s 47,285, indicating some level of popularity, the cost difference might be a deciding factor for many consumers.

Which should you buy?

Ultimately, the choice between the Makita 9557NB and the RhovixStar Brushless Angle Grinder hinges on your specific needs and preferences. If you require a powerful, reliable corded grinder for heavy-duty tasks, the Makita is an excellent choice.
