Rain day fun comparing new grinder with old

[Biggie]

I bought a bosch brushless grinder and it was raining so I thought i would compare it to some of my other grinders to see how it performs.  I pretty much just switched back and forth between grinders cleaning up the welding table so it was nothing more than playing with my toys.  What I found wasn't anything too surprising the new bosch is pretty much right on par with the m18 fuel and the dewalt 20v brushless.  I have to say I give credit to the tools review guys as I'm sure it takes a lot of time and work to push the tools to a point of seeing a difference between them. At the same time I would say its almost splitting hairs between the three "18v"  brushless grinders that I have and I don't really see one being superior to the others.  The ergonomics is one area that could be debated but that is probably more a personal preference thing.  As far as power is concerned the dewalt 60v is still the king of 4.5-5" grinders, it just has the power to keep the rpms up and that's even with the 2/6ah flexvolt battery.  The new m18 2981 is close and a step up from the others but its not the 60v and I personally don't really care for the ergonomics of it as it feels to long.  The old brushed grinders all get a performance bump from having new big high performance batteries but even with them they're still a step down from the brushless grinders with 5.0ah batteries.

And all pale compared to mid range or better corded. My M18 is awesome in the field and tight spaces but if I have to say remove paint/scale on a large area corded wins every time.

Yep corded is better for prolonged use and we have a shelf full of them and that's where they stay 99% of the time.  There are definitely people out there that still need corded and 10 years ago I would have said cordless grinders are useless but battery technology has really come a long way and they work for the way we use them.
