The Milwaukee M12 FUEL Die Grinder, priced at $239.95, is designed for professional use, delivering performance and power. With a sales rank of 48,356, it may appeal more to users looking for industrial-level capability rather than casual users.

The tool is notable for its compact size, enabling access to tight spaces where traditional grinders may struggle. With a four-mode speed control and a responsive variable-speed trigger, users can achieve precise control over their work, making it an excellent choice for detailed tasks in various applications.
Price Comparison
The AOBEN Cordless Angle Grinder is significantly less expensive than the Milwaukee M12 FUEL Die Grinder, with a price difference of about $159.96. Specifically, the AOBEN costs $79.99, while the Milwaukee is priced at $239.95. This makes the AOBEN approximately 67% cheaper than the Milwaukee option, making it more accessible for users on a budget.
For those who need a reliable tool for occasional use or lighter tasks, the AOBEN presents a compelling choice without compromising essential features. Conversely, the Milwaukee's higher price point reflects its advanced technology and professional-grade performance, justifying its cost for those who require a more powerful tool for demanding applications.
Power and Performance
In terms of power, the Milwaukee M12 FUEL Die Grinder stands out with its 0.3 HP motor output and 20% more power compared to pneumatic alternatives. This makes it ideal for users who need robust performance under demanding conditions. The AOBEN, while effective, operates with a brushless motor that, while efficient and long-lasting, does not specify a comparable horsepower rating.
The AOBEN’s adjustable speeds (maxing out at 9,500 RPM) provide versatility for various tasks, but the Milwaukee’s four-mode RPM control offers added flexibility in performance settings. Users who prioritize power and advanced control options may lean towards the Milwaukee for heavy-duty applications.
Battery Life and Convenience
The AOBEN Cordless Angle Grinder comes with two 4.0Ah batteries, allowing for extended operational time without the hassle of recharging frequently. This feature is especially beneficial for users who may work in remote areas where power outlets are not available. Its design promotes ease of use and portability, making it a practical choice for on-the-go tasks.
On the other hand, the Milwaukee M12 FUEL Die Grinder operates on the M12 REDLITHIUM battery technology, which is known for its longevity and performance. However, it is sold as a tool-only option, requiring users to purchase batteries and chargers separately, adding to the overall investment. Users prioritizing convenience may find the AOBEN’s complete kit more appealing for immediate use.
Design and Usability
The AOBEN Cordless Angle Grinder features a compact and handy design, making it comfortable to hold during operation. The inclusion of two protective wheel guards enhances safety, which is crucial when performing cutting tasks. The design also facilitates easy wheel changes thanks to its spindle lock feature, ensuring efficiency in workflow.
Meanwhile, the Milwaukee M12 FUEL Die Grinder boasts a best-in-class size that allows it to fit into tight spaces effectively. Its responsive variable-speed trigger offers excellent control, enhancing usability for intricate tasks. While both tools are designed for ease of use, the choice will depend on the specific applications and user preferences regarding comfort and accessibility.
Intended Use Cases
The AOBEN Cordless Angle Grinder is suitable for a variety of applications, including metal cutting, grinding, and polishing, making it an excellent tool for DIY projects and light to moderate professional tasks. Its versatility and affordability make it a suitable choice for hobbyists and those who occasionally need a grinder.
In contrast, the Milwaukee M12 FUEL Die Grinder is designed for professional service mechanics and users who require a tool capable of handling heavier workloads with more power. Its advanced motor technology and compact design make it ideal for precision work in automotive and industrial settings, where performance and efficiency are critical.
Which should you buy?

The AOBEN offers an attractive price point of $79.99 and a complete kit with batteries, making it ideal for casual users or those on a budget. Its multifunctionality and ease of use make it a great entry-level option for various tasks.
On the other hand, if you require a powerful tool for professional applications and don’t mind spending more, the Milwaukee’s advanced features and superior power may justify the $239.95 investment. For serious users who prioritize performance and control, the Milwaukee is likely the better choice. In the end, assess your needs to determine which tool aligns best with your requirements.
