Having recently purchased the DeWalt DW758 bench grinder for use in my shop, I can say that it is definitely a good value. The ¾ HP capacitor-start motor comes up to speed quickly, runs smoothly with steady speed and ample power for most any grinding need. Overall, it is a very good heavy-duty general-use grinder.
The stamped steel wheel guards are not as sturdy or easy to remove as the cast iron guards on other manufactures more expensive models. The DW758's guards have screws on the top and bottom, instead of on the side, which can be difficult to remove when the grinder is mounted to a bench. A small right-angle "Yankee" ratcheting screwdriver makes bottom screw removal much easier and more practical than unbolting the grinder from the bench to change wheels. This probably won't even be an issue for most users, given the relative longevity and infrequent changing of grinding wheels with normal use.
The DW758's shaft bearings are sealed and require disassembly for lubrication. DeWalt recommends having the bearings serviced by one of their Authorized Service Centers every six weeks to six months, depending on the severity of use. This could add up to quite a substantial cost over the life of the tool, given the minimum "bench fee" most Service Centers have, as well as through lost productivity to businesses from having a tool or piece of equipment out of service. For a shop tool with a recommended maintenance schedule this frequent, it would probably be better if the unit had capped grease fittings and plugs to allow relubrication as required in the shop, without having to remove it and take it to a service center.
The grinders tools rests work well, are sturdy, and can be tilted with the use of the supplied allen wrench to change the grinding angle, which is a very useful feature.

The price was the best on the Internet, especially with the Amazon super saver shipping. Delivery was faster than expected. However, when I received the machine and turned it ON, I was seriously disappointed with its performance. The course (36 grit) wheel mounted on the right had a very bad wobble to it. Visually, it looked like 1/8", but a close measurement showed it to be little under 1/16" total side to side, enough to vibrate the machine and the bench it was sitting on. I thought about shipping everything back, but then looked at a possible $28.89 shipping charge, and decided to see if I could fix it myself.

I removed both wheels and moved the wobbly right-hand (course) wheel to the left hand side. It made no difference in the wobble, so I figured it wasn't the mounting hardware itself. I experimented with a few layers of black electrical tape shimmed on the inside of the wheel under the mounting washer and found that four layers of tape removed the wobble almost entirely. I also mounted two layers under the fine wheel mounting so that the small amount of wobble that it had is nearly gone. Results - an acceptable grinder.

Pros: Lowest Internet price, fast shipping, OK after wheel wobble fixed as above. 8" wheels larger than motor case makes it easier to grind extended objects.

Cons: Made in China, 1 bad wheel wobble, requires factory service to oil machine, no light, no quenching cup.

Other comments: I found that my old 6" grinder had as much wheel wobble as the new Dewalt, but never noticed it even after several decades of use. I checked out several Sears 8" grinders manually. One was near perfect, the other had a slight wobble. Not allowed to turn them ON.

As machinist for 40 years here is what I found.
1. Poorly written instructions.
2. Mounted to a Grizzly bench grinder stand you can't turn it off fast enough due to the vibration.
3. Upon inspection the wheels run out laterally .080 on the left and .045 on the right .
4. Removing the left hand nut I find the nuts have been overly tight bending the stamped washers against the spacer to the bearing.
5. Today I machined out 4 new wheel /arbor washers only to get a similar result but better.
6. Upon removing the bearing spacer the ends are not perpendicular to the bore.
7. I removed the armature the bearings are rough and need replaced right out of the box.
8. I am going to machine the spacers and replace the bearings with a good quality manufacturer .
summary: without a machine shop avoid this unit!!!!

I am a DeWalt fan and may well own %50 of their product line, but I won't own this. If you want the same thing buy the $69 grinder and a can of yellow paint (Frequently bought together)and you will have the same quality of tool.

I set it on the work bench plugged it in and turned it on, and Immediately the entire work bench began to vibrate. My Dewalt 20 volt charger with battery in it nearly walked off the bench along with other things.

Even Walmart laughs at this thing, talk about cheap Chinese junk with an explanation point!!

I returned it and bought the Metabo, it may be twice as much in cost, but it will grid anything to precision, unlike the DeWalt which with unbalanced wheels will only be good for lawn mower blades.
