Craftsman 6" Var Spd Grinder makes dull task fun again

I spent over an hour cleaning rust off tools after setting the bench grinder up.  The variable speed feature is cool and the weight of the unit makes it wery solid even before I mounted it to the bench top.  The grinding wheels and brushes are very easy to change out and the flexible lamp is very helpful.  I would strongly recommend the Bench Grinder.

This item is ok. Not impressed though. Works.

This item was ok. Not really impressed though. Could be better guides on it for standard grinding like chisels, planes, axes etc. I would bolt this to the table as it does wobble a bit. Needs better guides.

Great grinder. I'm not a professional, just a weekend garage warrior. I mounted this to a wood work bench. There is not any vibration and runs smooth. The only down side is the wire wheel that came with it, it seems cheap and falls apart when cleaning tools. Easy fix. All in all love it.

I purchased this as a Christmas gift for my husband. He loves the Variable Speed that this offers. He has used it a few times for light buffing, and looks forward to using it to its full potential with some of his upcoming summer projects.

Good for limited light duty work.

After buying this grinder I knew I made a mistake. It works fine on light duty projects but with only slight pressure on the wire brush or grinding wheel you can actually bring it to a dead stop. The bench light is a nice idea but the vibration from the grinder shakes the filaments loose in any light bulb you put in it and burns it out quickly. When I buy another grinder in the future and I will, it will certainly have more power.

Great For the Price

Can't beat the price for what you get here. We've had many other bench top grinders in the past and this one knocks the others out of the park so to speak. Can't go wrong with Craftsman!

Not bad for a 6" grinder.

Light duty machine. The supplied grinding wheel and wire wheel need upgrading, but that is not too expensive to do. Spindle runout was less than 0.001 TIR.

Super Grinder

First time I used this tool it was great. I have 2 Zro-Trn mowers and it worked great at sharpening the blades. Also used it for my gardening tools and I used the variable speed. Great Feature.

Great little grinder

Purchased this on sale a few weeks ago and used it to sharpen all my dull drill bits, two lawn mower blades, and an axe; so it's probably paid for itself already. I also purchased a 100 grit wheel for finer honing of some woodworking tools. The brass wire wheel that comes with unit is kind of cheesy, but worked fine for cleaning rust off of some long bolts - now I don't have to replace them. I put a compact 15W compact fluorescent bulb in the lamp fixture- plenty of light. For the price and all the features on this grinder it's a great value. Btw, I looked at the cheapo HF Tools grinders - don't waste your time or money - they have nothing that comes close to this. Some reviewers mentioned low power - mayb if you're doing heavy metal grinding you'd need something with a bigger motor but for me, i has plenty of power for all my sharpening and light grinding jobs, and is a nice size for my small workshop.

so far so good

I haven't used it for everything yet. It has a lot of power. The wire wheel is noisy with the wires hitting the sides. I guess i'm gonna have to trim the wild ones off.

Best shop tool in my garage!

Versatile tool that performs many tasks with ease; sharpening, cleaning, descaling, buffing, and many more. The variable speed allows me to setup the speed to match the particular material I'm working. Looking forward to many years of trouble-free work.

Great grinder for the money

Picked it up on sale and have done some light grinding and wire wheel use so far. Will give it a good test shortly after doing some welding to see how well it does. I'm sure it will be more than adequate for what I will be using it for. I really like the variable speed option. The wire wheel doesn't seem like it's going to last very long. Will changing it out to a sturdier one when it's finished.

No power. Takes 15 secs to get up to speed. Either out of balance or shaft not completely straight, so it wobbled/viabrated pretty bad once it got up to speed. Set it up, started it, saw that it was not up to my equipment standards and should not be up to the craftsmen brand standards and immediately returned it. I am concerned about craftmen putting their name on this. I am huge fan and hope this is not a sign of things to come.
