I'm replacing my at home tools(ryobi) with Herc when they fail. I've been very impressed with the 20V Drill, Impact driver and Circular saw. The tire shop down the street has all hurc impact wrenches, and have said they haven't have any problems. And they are all daily use. 5 year warranty. Unless I find out something horrible about them, I'm going to keep switching. I'd give a lot for a nail gun. Answer from Adventurous_War_5377 on reddit.com

r/harborfreight on Reddit: Cordless Hercules Angle Grinder - Worth it or No?
March 23, 2024 -
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.

EVERY cordless grinder lacks power and duration That one will run a shorter time than the $10 corded one takes to over heat Big jobs demand a big corded grinder. Or you can do 3 $10 ones and just swap as soon as one gets hot Overheating any grinder’s motor or tranny will kill it Cordless grinders are best for small, quick, niche jobs where running an extension cord is a PITA

Hercules Angle Grinder
April 15, 2025 - For most users, I recommend starting with the standard 4-1/2″ corded model. If you already own other Hercules 20V tools, the cordless version makes a logical addition to your collection. While angle grinders aren’t traditional woodworking tools, they’ve become increasingly popular for certain wood-shaping tasks.
