5Solid, Great Value, Powerful Performance!  Jul 07, 2009 By Flynn Farralone
I was installing a new sink in the kitchen and had to enlarge the opening to accomodate it, which meant cutting through granite tile. After much research, it seemed the best way to do it was to use an angle grinder fitted with a diamond blade. I didn't want to make a big investment so I found the Porter-Cable model at Lowe's for $39.99 and was all set to buy it, but this model was right next to it for only $5 more -- plus it came with a case and 5 grinding disks. I'd read that the Hitachi was a solid tool so I went for it. I sure am glad I did -- it is incredible! So small but with so much power, and is very solidly built. Changing the disk was simple. I was very pleased. For general use, it's more than sufficient for most DIY'ers.

I am puzzled why the Hitachi's handle is angled slightly inward -- all the other grinders have their handles at a 90-degree angle from the body. It didn't affect performance, but I don't see the rationale.

At any rate, it's totally worth it. With the diamond blade, it made a 1" deep, 36" long cut through GRANITE in about 4 minutes (including brief rests) -- I was amazed. I used a Hitachi diamond blade for dry cutting -- it was incredible!

5Just buy the best - you can't go wrong  Mar 15, 2006 By John
I now have four of the best quality grinders on the market. Without telling you all the brands I wanted this grinder because of the quality put into Hitachi products. This is a very well made 4 1/2 inch grinder with a heavy duty rating & great quality. The grinder is a few onces heaver but that is why it's more heavy duty. I placed a 3/4" diamond blade in this grinder and had no problem removing concrete & mortar in one pass between the brick joints. None of my other grinders could handle the size or load this grinder can handle. Hitachi puts out fantastic quality tools for pros and homeowners. If you need this type of tool don't waste your money on a cheap grinder, this one will put the others to shame.

5Bang for the Buck  Sep 12, 2011 By Jeff
I bought this about a year ago and every time I use it I like it more. This tool feels solid, powerful, and comfortable to hold. I particularly like the fact that I can move the handle to either the right or left side depending on what I'm cutting and where I want to hold. The carying case is great too and keeps everything, including wheels, in one handy place. Drop a cut-off wheel in this and say goodbye to your Dremel. (Check out the Dewalt cut-off disks though as other brands don't have the 7/8" arbor in a 4.5" disk.) I have to admit that I'm not using this thing every day, but I would expect that for any user except a contract this should be all you need, and a at good price.

5Excellent Grinder  Aug 20, 2006 By J. Albricht
We use this grider to trim the hoofs on our dairy cattle. It is the only one that has lasted more than 1 yr. We are on our 3rd one now. A little on the heavy side, but the durability is worth the extra weight. Until we found this grinder, we were going through different one every week to a month. I've bought 3 and I'll buy more.

5Great Grinder  Aug 11, 2004 By Blake Imeson
Price is little steep @ $90 but is well worth it!

Paddle switch is very well designed it locks on easily one-handed ( I tried dewalt's and it did not work nearly as well)

Seems a little heavy @ first but is really easy to handle

Wish they included a case though

Works well with sanding kit
