I’m right now only using M12 Fuel tools for daily work, but I’d like to replace my corded angle grinder with a cordless one for ease of use on the job site. It doesn’t have to run for hours (I have several corded ones if I need one for heavy use) but instead just to make quick cuts, or smooth a surface, grind a transition. Most will likely be 5-10 minute jobs, or small fabrication projects.

I generally prefer thumb switch to paddle but I own both. I understand paddle might be safer with cordless in the event it gets dropped, because it can’t be shut off by pulling the plug.

I like the feel of the Bosch one, and I have an opportunity to get one with 2x 5.0 batteries and a charger for less than $200, but the X-lock proprietary discs bother me, as I have a collection of abrasives already that fit on a standard arbor.

Please share your experiences and recommendations? I’m open to other brands as well.

Interested in the Hercules Cordless Hercules Angle Grinder that has the on/off switch and NOT the one with the pressure grip squeeze handle. Had been looking at major brand names for a larger upcoming project when family member suggested I consider Harbor Freight Tools. Wanting to know if anyone has had good or bad experiences, any battery issues or charging issues?
Angle Grinder will be used with wire brushes and pads to remove rust from large trailer that was parked out in the elements so I am able to repaint the trailer after rust has been removed.

Potentially interested in continuing pieces from Hercules line as well such as eventually adding a circular saw, drill, and sander depending on if the line is worth it.
