Oregon Professional 120-Volt Bench Grinder Universal Saw Chain Sharpener, for All Chainsaw Chains (520-120)

I'm very happy with this. Oregon knows how to keep your chainsaw sharp! Well made and meant to last. Easy to operate and adjust different settings.

Easy set up and no more dull chains

Designed and built well. Easy to set and use.

Hubby enjoys using this so much he is sharpening all the neighbors blades as well. I keep telling him he could charge them a little to help recover the cost but in the long run it was worth the $$ to me. Keeps him busy, he enjoys it and he is helping out others.

1st off th3 bad , I set up the grinder correctly, installed the 3/16 wheel, and the 1st chain i tried to sharpen the wheel shattered. And yes I checked it for cracks before installation, but still shattered. Besides that the 520 sharpener is fantastic ! I noticed a considerable difference sharpening my low profile chains. Every angle is available to get them back to razor sharpeness. I'm very happy with the grinder just wish the 3/16 wheel lasted longer than 20" worth of chain.

Great sharpener have not had a bad sharpening on it yet. I cut between 15-20 cord of wood a year. There is some play in the arm when you pull it down. I just put to one side and sharpener everything the same way. Like the ability to put the 2nd angle on the table.

sharpens good

I bought this for my father for Christmas as he has 4 different Stihl chainsaws he uses depending on the job, and we're constantly using files to hand sharpen chains. Rather than keep using files (can you really maintain a perfect 30 degree angle?), I thought this would add some much needed consistency to the process, and it has. We're still early in the use of this machine, but the construction of it is solid, and it has numerous adjustments for properly positioning the grinding wheel to the chain teeth. I will say that for someone new to this machine, it takes some practice and reading of the instructions carefully to make sure you get everything setup correctly -- use of this tool isn't "idiot proof." I think we'll get a lot of good use out of this. Probably a nitpick, but if I had to ding it for anything, I'd hit it for the stop screw when you pull down the grinder for the depth gauge. That screw seems a bit smaller than I'd like, and there appears to be a divot drilled into the lower arm near where that screw hits, but it's not properly aligned to actually hit it. It seems like a manufacturing miss for the divot in the wrong spot, and I'd prefer a heftier screw with a fine thread to adjust the depth of the grind by turning the stop bolt. Of course, Oregon didn't ask for my opinion on that.

Works very well and makes quick work of sharpening!

Should’ve order it ages ago. Chains cut amazing now. So quick and it sharpened perfectly everytime once your setup. Uniform sharpening was my issue by hand but now, exactly the same in every cutter.

Sharpened my chainsaws - worked great.

Unit was easy to use,worked great,to many plastic parts

1/8 grinding wheel cracks very easy. A $41 item is way to much to pay for
