When considering an angle grinder what diameter and arbor size seems to be the most common. After a bit of research online and with local hardware stores it seems as though the range is very scattered from 4" to 9" and that not all accessories are available for each size/arbor size. It would only make sense to buy one larger (7"+) in order to accomodate any possible accessory that is not made specifically for that size. For example when attempting to find cut off wheels with a 5/8" arbor I was only able to locate one that are 4" in diameter. Is there any reason why smaller wheels with the same arbor size could NOT be used?

The only grinders that I have found to last have been Metabo. 4 1/2" would be your best bet, although my 5" gets alot of use as well.

The Dewalt 4 1/2 inch grinder works good. I don't see a lot of 4 inch disks around here, but a lot of places have 4 1/2. The 4 1/2 inch is easy to use, I have arthritis, and have a lot of trouble holding anything, but I can hold the 4 1/2 inch and prop myself into position at the same time. With a cut off wheel it slices through welds very fast, as fast as I can replace the cutoff wheels. I'll have to try the norzon grinding disks to save a lot of changing of disks. I wouldn't try to use one of the larger grinders without a balancer like the ones Aero Motive make to hold it up.

Fwiw, I've got a 4.5" B&D grinder that has been worked darn hard, and never given me a lick of trouble.

I've used it to cut up cars into little pieces. I used it this summer to strip the paint off my entire house. I've used it for cutting up fiberglass boats.

Zero maintenance has ever been done to the unit.

I don't think you would want a 4" grinder. Not very powerfull. If your going to go with the smaller grinders , go with 4-1/2" grinder. They are a good all around grinder. My self , I like the "Metabo" grinders. My next choice would be "Makita" , then "Milwalkie" , etc..

I have, maybe $25.00 invested in three small grinders (4 1/2" I think) 2 of them are for 50 cycle elect. so they run faster on 60 cycle. I buy GOOD wheels and cut off disks. Seems to work fine.

Hi Keith,

The best all around grinder I've found is a Makitia model 9052?, 5", 10,000rpm, 5/8" arbor. It's light weight but will let you grind fairly hard without burning the motor up. I use a 6"x3/32" cut off wheel that I use for cutting SS and other metals. This works very well and fast.

I like keeping with the 5/8" arbor as you can interchange most wheels "IF" rated for the 10,000rpm. Watch the wheel rpm rating as a wheel not rated for high rpm will explode.

I also have a Milwaukee 9" for heavy grinding. I also buy the 7" heavy twisted wire wheels for rust/paint removal as these wires don't fly off easy like the smaller wire wheels.

I have a Milwaukee 4.5", 1/2" arbor that has a short body to it and it now sits on the shelf with cob webs. The wheel is just too close to the finger knuckle without a guard on.

Whatever size grinder you get, if you want a wheel that lasts alot longer and cuts better than the rest, go with a wheel made by Norton called "Norzon". They have some type of ceramic in them, and Norton claims they outlast other wheels by 6 to 1. In our experience though it's been more like 10 to 1. When you have alot of metal to remove nothing beats them. For most wheels if you look at the metal they remove it is basically small "dust", but with the Norzons you can actually see a small shaving similar to what you'd get from using a machine tool. Several years ago I had to cut a clearance relief in the walking beams on a crane to remove a part but couldn't get to it with a torch because of clearance and it being a major fire hazard because of all the grease. I used a 4 1/2 inch grinder with a Norzon wheel and cut a relief 4 inches long and close to 3/4 inch deep in a piece of steel 2 inches thick. I did all this lying on my back reaching over my head, and with that wheel was done in about an hour...I wouldn't have even thought about trying it with anything else besides this wheel. They are pricy, and I'd be lieing if I said they weren't. They are usually 4 to 5 times the price of the competetion, but for the life vs other brands, and the performance, they are well worth it..... .but that's just my opinion...

Go with a 4 or 4.5". The 7" is indeed a handful. It's too big & heavy for a normal person to hang onto for very long. My best pick it Metabo with their quick change system. There are is none better. None more expensive. Milwaukee, DeWalt, Mikita, etc are all good.

I have a 4" and a 7". I use the 4" probably ten to one over the larger one.

I've been using a Makita 4" for years. Before I bought a 14" chop saw about 2 years ago, the Makita was all that I had to cut metal for my welding projects. It is still going strong but you're right about finding wheels for it...4" cut-off wheels can be hard to find. The selection is better and easier to find with the 4-1/2 grinders. I think I'll get a 4-1/2" one soon and just keep the wire brush on the Makita and use the new one for grinding and cutting.
By the way, the "flap" type grinding/sanding wheels are wonderful. They produce a very smooth, shiny surface on steel without removing too much material.

I have both 4" and 4 1/2"
I prefer the 4" because of the lightweight and it is easier to get in tighter spaces. I also find the 4� has less of a tendency to get away from you.

Keith,

Slowpoke told you true... the large grinders (7" & 9" ) are for heavy industrial grinding and will wear you down much faster than their wheels.. I can't imagine an application for home use. The 4.5 is the most common home grinder and there are grinding and cutting wheels and polishing disc available... you can buy them from 14.00 at Harbor freight to over $100.00 for a good quality commercial grinder. I have both ends of the range and the middle. I've bought H.F. throwaways for limited use, I own a craftsman that I've had for years that is slowly dying and Santa brought me a new Milwaukee.. I love it !!

I'd recommend a name brand/.. Milwaukee, Porter Cable... they will last forever. There is definitely a difference in vibration, noise and tool life over the cheaper import tools. But if that is all you can afford ... just keep replacing them. I'd suggest a paddle switch... you have fewer problems ( the thumb switches tend to give up and won't stay in the on position) and if you drop it it stops.. I'd also absolutely recommend you never plug one in without safety glasses in place.. these things sling metal... in tiny pieces... but metal just the same.. protect your eyes... you don't get replacements very easily. More questions ?? you know where we are..

BTW check for the factory refurbished units on the net... some good units at cheaper prices ..

The most popular is the 4-1/2" size. The cut off wheels have a 7/8 hole to fit the built-in adapter on the 5/8 -11 arbor. The 5",6",7"& 9" grinders are for lots of heavy duty work, not what you would use for 90% of home/shop applications. They're heavy, bulky, unweildy, & cost considerably more than the 4-1/2" size. Do not use wheels/brushes that are made for a different size machine. The larger wheels can fly apart at the high speed of the 4-1/2" grinder. 4-1/2" grinders are dangerous enough running at 8000-10,000 rpm just using the correct size wheels & brushes. The wheels got thru skin & flesh a lot faster than metal. There are several thicknesses of cut off wheels & 3 types of wire brushes available at reasonable(?) prices plus the standard grinding wheels. Grinding and cut off wheels wear down with use, so you will eventually have a 2-1/2" wheel. And I wouldn't get a metric arbor grinder.
