I decided I need 1 or 2 additional angle grinders and I am wondering if anyone has moved up to the 5" models from the 4.5" size. I need one that i can really lean into when grinding and one that will work a little faster than the 4.5". I don't want to get into the big 7" ones because of the price.

Are the 5" ones worth the extra money?

If you want one you can lay on, look at the amps more than the size.

5" are nice cause sometimes that bigger wheel or cutoff disc gets areas a 4.5 won't. That's the only advantage I see.

I have 4.5 grinders that are 4.5a, 6a, 7a, 9a, and a Milwaukee that is 11a.

My only 5" is 9a.

Also have a metabo 6” at 12.2a

Look at 6” grinders. Same size as the 4.5 and 5 inch, but more power.

If you want to lean into a grinder get at least 10 amps and the 39.95 special isn't the one you want even it's 15 amps.

I have a big 7" one that you can lean into. I don't use it very often. I much prefer to work a little longer with my 2 pound air grinder vs using that 15 pound behemoth.

I'm with Arc and LD on this... need the power to lean on a grinder. A 5in will not give you necessarily more than a 4.5in... look at the amps comparing 110v models. Looking at the label for amperage is about the first thing I do when evaluating electric tools.

+1 on the Metabo bought at a rigging company auction for 60.00. Used as a grinder. Other brands get the wire brushes.

I can lean into my Nitto Kohki 4 1/2"" angle grinder. One horse power.
Didn't feel like going out to the shop to snap a pic but here's a link.

Just noticed its discontinued....

Wow, 30cfm. Better have a big compressor or you ain't grinding long.
I have a 100 gallon compressor with about 20 CFM, and you still ain't grinding long. Unless you have a big diesel compressor or something similar that would be about worthless. I don't think you could get there with 50 amp 220. That is solidly in 3 phase territory.
