Top Customer Reviews
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 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 unit comes supplied with 60 course-grit and 36 medium-grit wheels installed and can accept other 8" wheels with a face width of up to 1" and wire wheels with a face width of up to 1-1/4" as well as cotton buffing wheels. I have no problem at all recommending the DW758. The unit seems very well made, especially considering the modest price tag, and will no doubt last through many years of hard use.
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.
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 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.
I was suspicious of getting an 8-inch grinder for a little more than $100. I only ordered this one because my brother has the same grinder and told me it works fine. He was here when I plugged the grinder in and he couldn't believe how poorly it ran. His tool is older so maybe he bought his when DeWalt still cared about quality. This makes me suspicious of ALL DeWalt tools.
UPDATE: While waiting for UPS to pick up the grinder for return, we spent some time diagnosing the problem(s). The cone washers that hold the wheels are stamped and, as others have noted, they aren't necessarily flat/true. But we also found that the shoulder on the shaft that the inside cone washer seats against had a high spot on it. So even if I replaced or machined the cone washers, the wheel would never run true.
These are simple machines: no gears or complex mechanisms, just a motor with an extended shaft. It's almost harder to make it wrong than to make it right. It's not a "made in China" problem. The Apple computer I'm using to write this review was also made in China and it's a beautifully crafted machine. It's a failure by DeWalt to ensure their products adhere to even modest QA/QC standards.
