4.0 out of 5 stars DeWalt DW758 December 8, 2001

By A Customer

Color Name:NA

Having recently purchased the DeWalt DW758 bench grinder for use in my shop, I can say that it is definitely a good value. The ľ 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 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. Read more ›

3.0 out of 5 stars Had to fix wobble. March 4, 2007

By Allan Lloyd

Color Name:NA

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.

5.0 out of 5 stars A superbly built grinder November 20, 2000

By A Customer

Color Name:NA|Amazon Verified Purchase

...this is a beautiful piece of work. It is well built and remarkably well balanced such that I really don't need to bolt it down. Its bearings are perfect as it seems it takes forever to stop once the power is turned off. The wheels are well matched for general use and fairly easy to change once the small screws holding the wheel covers are removed. The tool rests are sturdy and steady and easy to adjust and they stay put. I use it all the time with great results in my home shop. My only suggestion is that a work light should be included and it would be handy if there were a 2nd speed. Overall a real bargain for this 8" grinder.

2.0 out of 5 stars Decent grinder with poor wheels December 12, 2007

By J. Sharp

Color Name:NA

My grinder has the same problem many others have reported. The wheels are far out of true. This leads to high vibration and will certainly shorten the life of the grinder. I'm still trying to decide what to do. Exchange it for another from Amazon, ship it to a Dewalt service center for exchange, or just get a refund and buy another brand. There's another option that might also work - buy higher quality wheels from a different company. The latter would likely be the best option if it wasn't so costly.

4.0 out of 5 stars Nice but don't forget to dress the wheels! November 24, 2006

By Jay Ras

Color Name:NA

This is a nice heavy duty, well made bench grinder. Run's smoothly with plenty of power. Delivered to my door for a little over a hundred bucks is great. I'm rather concerned that Dewalt didn't mention the importance of dressing the grinding wheels. I understand not sending a dressing tool with the unit to keep the price down but not covering this very important subject in the manual is not very responsible. At least they didn't advise pushing harder as the wheel loads up. If you don't have some type of wheel dresser please get one and use it!
