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

What is the best cordless grinder that harbor freight offers. Any deals with batteries chargers ect? Anyone have a coupon I can have? Thank you
The Hercules and bauer brushless grinders are basically identical, Herc might be slightly more powerful but it might be the bigger batteries. I use both in professional automotive and fab work and haven’t crapped either out yet in a year. I still use the corded dewalt to really grind fat welds because they spin faster and are slightly more powerful, but for most tasks these cordless grinders have been surprisingly stout compared to the crappy Ryobi I got.

Thoughts on Harbor Freight Angle Grinder
Harbor Freight tools can be super cheap for a reason, but often times for someone like you or a job like this that's plenty fine. If it breaks after awhile are you really out anything? Yeah yeah we shouldn't be buying disposable tools, but sometimes you gotta. More 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.

r/HomeImprovement on Reddit: Thoughts on Harbor Freight Angle Grinder
October 19, 2021 -

Hey everyone!

I've moved a few walls in my basement which were nailed into the concrete ground. The nails were mostly cut through and flush with the concrete. A few have a bit of a jagged edge sticking out yet though. I've tried a few different techniques with tools I have on hand but no luck.

So I'm looking at a really cheap angle grinder from Harbor Freight. $10 cheap. Couldn't figure out hyperlink, sorry :(

https://www.harborfreight.com/43-amp-4-12-in-slide-switch-angle-grinder-69645.html?utm_source=google&utm_medium=cpc&utm_campaign=12126402660&campaignid=12126402660&utm_content=118355052953&adsetid=118355052953&product=69645&store=356&gclid=EAIaIQobChMIiPKTqJ3V8wIVbWpvBB0m5ADkEAQYAiABEgLFrvD_BwE

I only need it for these like 2 nails (seriously 2) and then I have no idea when I would use it next. It just feels too cheap, too good to be true, even with great reviews... these nails are 1/4 diameter btw. So, what do y'all think?
