Since this is a tool-only kit, you’ll need to buy the battery and charger separately, which could increase the overall cost. This grinder suits users who want cordless convenience and decent power in a well-known brand, but those needing longer continuous work should consider battery options carefully.

This compact, versatile grinder delivers good speed and power, making it a practical choice for various applications. Users should ensure they have the necessary batteries and accessories to meet their specific needs.

Its speed and performance are enhanced by Milwaukee's FUEL technology, allowing for efficient work. Users typically appreciate its ergonomic design, which helps with grip and comfort during use.

However, there are a couple of drawbacks to consider. The battery is sold separately, which can add to the overall cost if you don't already own compatible batteries. Some users might find that the power output is limited compared to larger, corded models, particularly for more demanding tasks. Additionally, while the safety features are reasonable, they aren't as robust as those found in some higher-end models, so extra caution is advised when using the tool.
