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.

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.

r/harborfreight on Reddit: Experience with the Hercules 56459 11A 4 1/2" Angle Grinder?
July 21, 2021 -

I'm looking into an angle grinder, and am debating between the Hercules 56459 and the DeWalt DWE402. Both are 11 Amp corded angle grinders that spin a 4 1/2" wheel at 11,000 RPM. All my cordless tools are DeWalt, but since this tool is corded, I don't need to go with something that I already have batteries for.

From what I saw of the few reviews online, the Hercules seems to be a clone of the DeWalt (it's even listed on HF's website as being comparable). I'm wondering if the DeWalt is worth the extra $25 over the Hercules.

r/harborfreight on Reddit: Hercules vs Bauer Angle Grinder
August 7, 2023 -

Anyone have experience with both of these? Thoughts on one vs the other?

I don't plan to use it a ton. I just have a couple of projects I need one for.

  1. I need to level the concrete in my garage so I can put down an epoxy floor. This involves grinding down any little high spots and cleaning up any cracks before patching and putting down leveling cement.

  2. I have a project off-roader I'm working on, and I need to cut out/grind down some rust.

I don't think either of these should be particularly hard on the tool, but I haven't really done either before. There are deals going for both brands over the next couple of weeks, so now seems like a good time to buy.
