Beats the Competition!

I was originally looking at a grinder at ***** for a few dollars less. What turned me on about this grinder was the tool rests. The Overall machine is over 2 inches wider, giving you more room to work with, and the tool rests are at least twice, if not three times the size and strength! I also like how the craftsman grinder light function can be turned on even with the grinder off. The quench tray is also more than double in size. Finally, What really sold me, was the drill bit groove is a separate plate! Loosen the screw, turn it down 90 degrees and tighten it back up. I couldn't stand being stuck with a permanent 60 degree v-groove. I have only found a couple little things I would change about the unit. The wheel housing/ guard is comparable to other brands, weak in design. The tool rests to bolt to a bracket that bolts to this housing (as all grinders do) but since the material is thinner than I'd desire, it seems to give a little flex to the tool rests. Its not near as bad as other similar priced grinders, but not adequately better either. and I removed the cheap wheel dresser and holder as it got in the way of my light. Yes I did have the vibration issue that everyone seems to have, and yes, the grind wheel was slightly out of round, but that is not what causes the vibration. I removed the wire wheel and ran it with one wheel (even being out of round) and had ZERO vibration just sitting freely on the bench. I bought a very cheap $6.00 8" grind wheel to test my theory and guess what... ZERO vibration (with two out of round wheels). The cheap fine wire bristle wheel that comes with it tends to smack the wires against the housing a little, is out of round, and created a wind turbulence and/or harmonic that creates the vibration. Even a high end stiff wire wheel adds to grinder vibration (just not as bad as this stock one). I wish there 4 mounting holes but there are only two. Bolt the grinder to a heavy pedestal or bench, or don't use (or purchase a better) wire wheel. All in all, this is a great grinder. Im used to using Jet and Dayton grinders at work and this one will run neck and neck with those higher end brands. I couldn't be happier, and never write reviews but just had to on this one. Hope this helps set the record straight for future buyers on the vibration issue. Happy Grinding!

Don't Buy this Bench Grinder Buy Porter Cable Version.

Sears has bought this Bench Grinder from the cheapest provider. The Grinder is out of balance. Sears parts doesn't have any wire wheels in stock to replace the defective ones. The grinder vibrates so much that you have to turn it off. I tried rotating both wheels as well as the arbors with no luck. You can buy Porter Cable's same version of this at ****** for $120.

Very pleased. I would definitely buy this product again. I recommend it highly.


Picked it up today. Easy assembly. Runs smoothly and wobble free. Love the variable speed since a lot of tasks require slower rpms. Didn't have any of the problems noted in other reviews. The inclusion of a dressing tool was a nice bonus which Craftsman should add to the item details and specs. I ran it on a workbench without attaching it in any fashion and it remained in place while I used both wheels through the full speed range. The bit sharpener is now an attachment that goes over a flat tool rest which was also a nice surprise. The light isn't quite rigid enough, but that isn't a big issue.

Bent guard upon arrival


Got this with the guard around the wire wheel bent. Otherwise, it's an average bench grinder. Haven't used it a lot, but it's better than some of the cheap competitors, but not a professional quality item.

Buyer beware


After buying the grinder, I found out that the motor and capacitor are obsolete. This product is not supported by Sears. BEWARE!

I recommend this tool to anyone wanting top quality.


Great for sharpening mower blades and all types of grinding. The wire wheel is great for buffing. The variable speed allows for a lot of versatility. The light helps with detail grinding and buffing work. The drill bit sharpening guide is a nice accessory.
