Bits Titanium Plated Diamond Sharpening Wheels - High Hardness 7/32 chainsaw files for Electric Chainsaw Sharpener. 8 pcs. (7/32'', 5.5mm)

EzzDoo give the impression that these are made by a father and son organization locally ("My dad is a chainsaw worker, we made this tool just to get him out of the sharpening hassle."). In fact they are made in China, (it says so right on the box) - nothing intrisically wrong with that, but it deflated my notion I was buying something special hopefully made in the USA.The 8 little grinding wheels came rattling around loose in a plastic box, which is not a good way to send abrasive materials as they arrived chipped, (a small piece of "Chinese" foam rubber would have prevented them getting damaged). The gold "titanium" coating soon came off one side of the wheel when I used it, which is odd as the wheels revolve, not oscillate back and forth, but they did sharpen my Stihl chain. They are cheaper and better than those made by Dremel, which tend to disintegrate very quickly, and 3 chains sharpened out of a single wheel isn't too bad. They are just regular budget priced Chinese tools, which often are quite good for the money, but please spare me the bit about "my Dad and Me, etc, etc". Perhaps, like "Betty Crocker", "Dad" is a fictional character dreamed up by some guy in the Marketing Dept. Would I buy them again? Probably not. They arrived chipped, they are nothing special and I feel duped by the "made especially for my daddy", bit.

I've got a Stihl 20" Farm Boss and I hate sharpening the chain(s). Lately I've vowed to sharpen it each time with the Stihl hand file after each day using it, seems to help.Then my son mentioned something about a dremel?I picked one up and while looking at the reviews found out you can sharpen a chain saw with it. Wow was I impressed with these little grinders. I sharpened 5 old chains and each one took 5-10 minute to do both sides. Amazing results. I just have to bring the Dremel tool up to the lake every so often, but bye bye hand file, except for emergencies!One file did 5 chains - one worn spot on that but 5 chains with one stone is pretty impressive to me. Also, I probably sharpened them more than I needed to make sure all the surfaces were at the proper angle of 30 degrees. I'm guessing old timers will question this vs a manual file but for my time and money this is a no brainer.Great product

I use my chain saws a lot to clear thousands of dead cedar trees on my property. I have to sharpen my chains frequently to keep them cutting efficiently, especially when I let my high school helpers use them I saw your product when I was replacing the sharpening stones for my tool. When I got them, I found that they worked better than any other one I have tried. THANKS FOR A GREAT PRODUCT!!!!!!

Ok for sharpening my chain saw. Dont expect long life. Sharpen on 28 inch chain and that is about it. Might work on two, but then it is of no use. I use lots of these from different manufacturers and find very little difference among them. Use, and throw away.

I use this to sharpen my chainsaw. I had bought some cheap stone ones from Amazon & would go through 4 bits for 1 sharpening. I just used this & kept the bit for the next time also. Chain is sharper too. Worth it

Use these to sharpen my 14" chain for Stihl. dulls very very quickly. Will not be buying again.

I still use only 1 bit to grind 6 chainsFast results and I am happy. Good quality

I've sharpened 10 chains with 2 bits. Works great on my Dremel tool and lasts longer than Dremel brand and is significantly cheaper. Give them a shot

Thin layer of diamond on top-as a professional arborist- they do not withstand; 2-3 sharpens per stone.1 star

Sharpens real well and easy but was only able to get 3 chains out of one wheel.

Works well with low speed drill

they seem okay

Does the job😍
