Not for constant heavy use.

While this grinder is powerful and versatile, its not ideal for constant heavy-duty use in a metalworking shop. The 4Ah battery drains quickly under heavy loads, so youll need at least two batteries to keep working without interruptions. For occasional use or lighter tasks, though, its fantastic. The power and portability make it a great addition to any toolkit.

Highly recommend!

This is an excellent tooldurable, powerful, and easy to use. The 4Ah battery is sufficient for most tasks, and the grinder itself feels well-made. Whether youre cutting, grinding, or polishing, this tool gets the job done. Definitely worth the investment.

Durable and efficient.

This grinder has been a workhorse for me, handling everything from cutting concrete to thick metals. The 4Ah battery provides enough power for most tasks, but for heavy-duty work, I d recommend having a spare battery on hand. Its a great tool for professionals or DIYers who need versatility.

Powerful and reliable!

Ive been very impressed with the power and build quality of this grinder. It handles tough jobs like cutting concrete and thick metal with ease, especially when paired with a 4Ah or larger battery. Its a solid tool for anyone needing a reliable cordless grinder.

Guard is a bit tricky.

The shield/guard on this grinder is functional but can be a little finicky to adjust. Theres a small metal lever you need to depress to rotate or remove it, and getting it back on requires precise alignment. Its not a dealbreaker, but its something to be aware of if you frequently adjust the guard.
