Any preference? I am going to use it for all things cuting and grinding. Would the larger one just get more work done faster or is it too haevy to use all day and not worth it? Also, I will assume that there will be more wheels for the 4.5"

TIA

The larger one is heavier and will make you tired quicker. I like the 4.5" because around here the discs and such are easier to find than the ones for the 7". 7" will get things done a little quicker though. 4.5" is better if your working under a car or in tight spaces.
Guess they both have their pro's & con's.

7" angle grinders are back breakers!

Metabo makes the best angle grinder for cutting in all sizes IMO, they are not good for grinding though, at least with the cutting wheels.

Cutting wheels are not made for grinding..........use the flap wheels that are made for the purpose. Can get them in diifferent grits and for different types of metal.

I already have a RotoZip that I can use for "some" cutting but it takes thir special 3.5" wheels so they get expensive.

I compared the 4.5 and 7 inch grinders and the 4.5 weighs 10.5 lbs and the 7 weighs 11.5. There is only a one pound difference. The performance looks the same in terms of the motor amps and rpms but the COST is nearly twice as much. I am thinking the 4.5 will fit my needs.

At those weights what grinders are you looking at? Most 4.5" grinders fall in the 3.5 to 5 lb range. The 5" are about 6 -7lb range. For general use around the home shop the 4.5" grinder is the best choice. And take it from someone who repairs power tools for a living I would look at the Hitachi line of grinders.

Craftsman states that hey wigh that much? I will check again as I thought it seemed like a lot. I saw a good write up on Milwaukee brand as well. I haven't seen the Hitachi brand? Lowes or Home Depot?

Thanks!!!

Get a variable speed whatever you get. You can use it for polishing.

My 7" must weigh four or five times what my little 4.5" weighs.

I have not had a Milwaukee grinder but I do have one of their cordless drills. This is the 5th cordless drill I have had and it has been the best one by a long shot. I wouldnt hesitate to buy one of their other products.

I have several Milwaukee power tools. They are always my first chioce. Sometimes I have lower my sights due to finances. They are powerful, well built and service parts are available. You can't go wrong with Wilwaukee.

P.S. I'm not a Milwaukee salesman.

get a grinder for gringing..a sander for sanding or buffing. That being said..get a 4 1/2 grinder. I have used one in work for over 13 years...Craftsman. I also have a sander/polisher that I put 8" 50 grit discs on and also buff with it. but that is a different animal. You want the 4 1/2 for grinding welds and such.

I ended up with a Dewalt 402. It has the paddle switch and three locations for the handle. It fits pretty well but I am not happy with how much debris shoots uo from it. I'll beat it up and see how long it lasts!!! lol
