Makita 9557NB 4-1/2" Angle Grinder vs Makita 9564CV 4-1/2-Inch SJS™ High-Power Angle Grinder

Overview of the Makita 9557NB and Makita 9564CV

The Makita 9557NB is priced at $84.01, making it about 60% cheaper than the Makita 9564CV, which costs $209.00. This significant price difference reflects the varying features and intended uses of both angle grinders. The 9557NB is designed for high output power with its 7.5 AMP motor, while the 9564CV offers advanced features and a more powerful 13 AMP motor. Understanding these differences will help users decide which tool best suits their needs.

Power and Performance

The Makita 9564CV boasts a more powerful 13 AMP motor compared to the 7.5 AMP motor of the Makita 9557NB. This difference allows the 9564CV to deliver variable speeds ranging from 2,800 to 10,500 RPM, making it suitable for a wider range of applications. Conversely, the 9557NB operates at a fixed speed of 11,000 RPM, which is still efficient for many tasks but may lack the versatility of its counterpart. The enhanced power and speed control features of the 9564CV position it as the superior choice for those requiring flexibility in their grinding tasks.

Design and Comfort

In terms of design, the Makita 9557NB is compact and lightweight, weighing only 4.5 lbs. This makes it comfortable for extended use, especially for tasks requiring precision and control. The 9564CV, however, is slightly heavier at 5.3 lbs but incorporates features like a barrel grip for better handling. Both models feature a protective varnish to extend tool life, but the 9564CV also benefits from a soft start feature, which helps prevent sudden jolts during startup. Users may prefer the lighter weight of the 9557NB for less demanding jobs, while the design of the 9564CV may appeal to those needing more power and control.

Durability and Construction

Durability is crucial for tools like angle grinders, and both the Makita 9557NB and 9564CV are designed with longevity in mind. The 9557NB features a protective zig-zag varnish that seals the armature from dust and debris, which enhances its lifespan. In contrast, the 9564CV utilizes an advanced labyrinth construction that not only seals the motor but also protects the bearings from contamination. Additionally, the 9564CV's SJS technology acts as a mechanical clutch, preventing gear damage in case of wheel binding. While both models are built to last, the added protective features of the 9564CV may provide more peace of mind for heavy-duty users.

Versatility in Usage

When it comes to versatility, the Makita 9564CV stands out with its variable speed control dial that allows users to adjust RPM based on the specific application. This feature is beneficial for tasks requiring different speeds, such as grinding, cutting, or polishing. The 9557NB, while powerful, does not offer this level of speed customization, operating at a steady 11,000 RPM. This makes the 9564CV a better option for professionals or serious DIY enthusiasts who engage in a variety of projects requiring different speeds and power levels.

Safety Features

Safety is paramount in power tools, and both the Makita 9557NB and 9564CV include essential safety features. The 9557NB offers a lock-on/off switch for convenience, while the 9564CV includes a constant speed control that prevents loss of speed under load, reducing the risk of kickback. Additionally, the soft start feature of the 9564CV ensures a smoother start-up, minimizing abrupt movements. While both grinders are safe to use, the 9564CV's advanced safety features may make it a more attractive option for users concerned about safety during demanding tasks.

Price Comparison

The price difference between the two models is significant, with the Makita 9557NB retailing for $84.01 and the Makita 9564CV priced at $209.00. This makes the 9557NB approximately 60% more affordable than the 9564CV. While cost is an important factor, it's essential to weigh it against the features and capabilities offered by each grinder. Users who primarily need a reliable tool for lighter tasks may find the 9557NB sufficient, while those who require advanced features and higher performance may justify the higher price of the 9564CV.

Which should you buy?

Choosing between the Makita 9557NB and the Makita 9564CV ultimately depends on your specific needs and budget. If you are looking for a lightweight, straightforward angle grinder for basic tasks, the 9557NB is a solid choice at $84.01. However, for those who require more power, versatility, and advanced features, the 9564CV, despite its higher price of $209.00, offers superior performance and durability. Assess your typical usage scenarios, and make a decision based on the features that matter most to you.
