Updated July 2026 — full head-to-head comparison.
Price Comparison
The Cordless Angle Grinder Compatible with Milwaukee M18 18V Battery is priced at $49.99, making it about 17% cheaper than the Makita 9557NB 4-1/2" Angle Grinder, which retails for $84.01. This price difference might be significant for budget-conscious consumers looking for a reliable tool without breaking the bank. While the SpomacGek grinder offers a more economical option, the Makita grinder's higher price may reflect its brand reputation and additional features.
Motor Performance
The Makita 9557NB features a powerful 7.5 AMP motor that delivers an impressive 11,000 RPM. In contrast, the Cordless Angle Grinder achieves a maximum speed of 8,000 RPM through its brushless motor. While both grinders are capable of handling various tasks, the Makita’s higher RPM indicates it may be better suited for high-output applications, providing faster grinding and cutting capabilities. Users who prioritize speed and power may lean towards the Makita, whereas those who value battery compatibility might favor the SpomacGek.
Design and Usability
The Cordless Angle Grinder boasts a user-friendly design with an adjustable side handle, making it suitable for both left-handed and right-handed users. This adaptability is beneficial for extended use and comfort. The Makita 9557NB also offers a compact design, weighing only 4.5 lbs., which enhances its portability and ease of handling. Both tools include features that facilitate user comfort and safety, but the SpomacGek's spindle lock for easy wheel changes sets it apart in terms of convenience.
Durability and Construction
When it comes to durability, the Makita 9557NB stands out with its protective zig-zag varnish that seals the armature from dust and debris, ensuring a longer tool life. The labyrinth construction also protects the drive gear and bearings from contamination. The Cordless Angle Grinder, while robust, does not highlight specific construction features for prolonged durability. Users who prioritize long-term investment in their tools may find the Makita's build quality more appealing, especially in demanding environments.
Safety Features
Safety is a crucial consideration in power tools, and both grinders are equipped with protective features. The Cordless Angle Grinder includes a protective switch, a quick-adjust guard, and a soft start function, which enhances user security by preventing accidental starts and ensuring quick shutdown. Meanwhile, the Makita 9557NB features a lock-on/off switch and a protective varnish for added safety. Both tools offer reliable safety mechanisms, but the SpomacGek's additional soft start and power failure protection may provide peace of mind for users concerned about safety during operation.
Versatility and Applications
The Cordless Angle Grinder is designed for a variety of applications, including metal cutting, surface treatment, and wood polishing, making it a versatile choice for DIY enthusiasts and professionals alike. Its compatibility with different brand wheels enhances its usability across various tasks. Conversely, the Makita 9557NB, while also versatile, is particularly noted for its high output power, making it ideal for more heavy-duty applications. Users looking for a tool that can handle a range of materials may find the SpomacGek grinder suitable, but those needing a more robust option might opt for the Makita.
Brand Reputation
Brand reputation can influence purchasing decisions significantly. Makita is widely recognized in the industry for producing reliable and high-quality power tools, which is reflected in its sales rank of 74,761. In contrast, the Cordless Angle Grinder has a sales rank of 64,143, indicating it is gaining traction but may not yet have the same level of brand recognition. Consumers who prioritize brand trust and after-sales support might gravitate towards the Makita, while those willing to experiment with newer brands may consider the SpomacGek.
Which should you buy?
Choosing between the Cordless Angle Grinder Compatible with Milwaukee M18 18V Battery and the Makita 9557NB 4-1/2" Angle Grinder ultimately depends on your specific needs and preferences. If you prioritize affordability and battery compatibility, the SpomacGek model at $49.99 is a compelling choice.

Consider your typical tasks, budget, and brand loyalty when making your decision.
