Performance Comparison
When it comes to performance, the AOBEN Cordless Angle Grinder features a brushless motor that significantly enhances its efficiency and durability, offering a maximum RPM of 9,500. This makes it well-suited for diverse tasks, including grinding and descaling various materials.
On the other hand, the AVID POWER Angle Grinder boasts a powerful 7.5-Amp motor with a higher RPM of 12,000, making it more suitable for heavy-duty applications. Users looking for a tool primarily for metal work and masonry might find the AVID POWER's performance more aligned with their needs, particularly for cutting through tougher materials.
Battery vs. Electric
The AOBEN grinder's cordless design provides unmatched convenience, allowing users to work without the limitations of a power cord. This aspect is particularly beneficial for outdoor projects or in areas where power sources are not readily available.
Conversely, the AVID POWER grinder relies on an electric connection, which ensures consistent power and eliminates the need for battery management. For users who prefer uninterrupted operation without the concern of battery life, the AVID POWER may be the better choice, especially for extended tasks.
Versatility of Use
Both grinders are marketed as versatile tools, but they cater to different user requirements. The AOBEN grinder offers three adjustable speeds, making it suitable for various applications including grinding, cutting, and polishing. Its design facilitates ease of use for multiple tasks, enhancing its versatility.
In contrast, the AVID POWER grinder is explicitly designed for metal work, masonry, and concrete tasks. It can handle a wide range of jobs, from sharpening lawn mower blades to cutting tiles. Its higher RPM and inclusion of a range of accessories make it particularly versatile for users with specific metalworking and masonry needs.

The AVID POWER grinder also emphasizes safety with a tool-free adjustable guard that can be set to deflect sparks and debris. Its lightweight construction, combined with a 2-position side handle, allows for a comfortable grip, reducing fatigue during prolonged use. This design makes it approachable for both novice and experienced users.

The AOBEN grinder comes as a comprehensive kit, including two batteries, a charger, a handle, multiple wheel guards, and various grinding and cutting wheels—all presented in a handy tool case. This extensive package adds value for users who want everything they need in one purchase.
In comparison, the AVID POWER grinder also includes a solid selection of accessories, such as multiple cutting and grinding wheels, a flap disc, and an auxiliary handle. While it may not match the extensive offering of the AOBEN kit, it does provide a complete starter set for users looking to dive directly into their projects.
Which should you buy?
Choosing between the AOBEN Cordless Angle Grinder and the AVID POWER Angle Grinder ultimately depends on your specific needs and preferences. If you prioritize portability and versatility, the AOBEN grinder, with its battery-powered design and adjustable speeds, is an excellent choice for various applications. However, if you are looking for a more powerful tool at a lower price point for heavy-duty tasks, the AVID POWER grinder stands out with its higher RPM and robust electric motor. Both tools have their unique strengths, making them suitable for different types of users and projects.
