DeWalt 20V MAX Flexvolt Advantage 4.5" to 5" Paddle Switch Angle Grinder (Tool Only) Expired

So, Flexvolt nomenclature is kinda screwy.

Flexvolt is more about the battery and DeWalt is taking liberties to confuse us proles. A 9ah battery is 9ah at 20v or 3ah at 60v. Math.

A 60v "Flexvolt" tool utilizes the Flexvolt 60/20v battery to run it at 60v. You cannot use a 20v battery.
A 20v "Flexvolt Advantage" utilizes the Flexvolt 60/20v battery to run it at 30ish volts or a regular battery at 20v
A 20v XR or brushed utilizes the Flexvolt 60/20v battery to run it at 20v for increased runtimes, or a regular battery at whatever.

Someone correct me if I'm wrong, but for a little bit "Flexvolt" could be bought at HD but not Lowes, and the "Flexvolt Advantage" was at Lowes but not HD. Not sure if thats still the case as I haven't added to my blackandyellow collection for a while, but as an owner of a "Flexvolt Advantage" drill I haven't noticed any huge power gains when using a bigger battery, the drill just weights more all the time.

For a DIYer this grinder is probably perfect. Maybe even overkill. The stock 20V brushless grinder is plenty. I've run mine on thicker stainless and 1/4" mild steel plate with zero issue. Takes down a padlock in seconds. A 4.5" grinder discs will do pretty much anything you need within reason, and the guard is set up for it. A guard that can also take 5" is either oversized for the 4.5 or under for the 5. So safety. Anytime you add a bigger dangerous spinny thing to something you don't use frequently, I question is the potential damages worth the extra half inch?

If you're a pro and the 6" is important to you then yes, get the full 60v Grinder (I know nothing of its finer features) but again, if it will run 4.5-6" discs, whats that blade guard dimension?

And as always: eye(better yet face), ear, AND HAND protection with these things if you're new to them. I'd be missing a good chunk of index finger if it wasn't for some decent gloves, and that was with a 40 grit sanding disc, a blade would have been worse. Always plan for something wrong to happen with these. Discs are somewhat of a fragile item too fyi. The resins breakdown over time and make compromise really old discs.

Best of luck.

I had a grinding wheel break causing the tool to 180 in the air and land on my hand near the index finger. Was not wearing gloves. Ended up in the ER and my hand has never been the same. Wear gloves please.

Also, the trigger on these is much easier to feather then those giant ON/OFF switches.

I honestly think his comment is common sense. Work place accidents do happen and protective gear helps minimize the injuries. He was just trying to be helpful imo
