Electric Chainsaw Sharpener Kit with TITANIUM-COATED Diamond Bits - High-Speed Chain saw Sharpener Tool and 6 High Hardness Sharpening Wheels For All Chainsaw Chains.

Just got it today and sharpened the blade of my 14inch cobalt chainsaw. Took me just a few minutes to figure out which diameter but to use and a few more minutes to get the motion down. The angle guide helped me keep it at 35 degrees. 10 minutes to sharpen the blade. I then finished a job I started yesterday with the dull blade. Got through some 8 inch sweet gum like butter!I used to drop my blades off at the store and wait a handful of days. Never again! This product does.make.it easier. Enjoy!

Used ONLY 2-times, then it would not turn on. I backed the brushes out to check for any issue and found none. Still would not start again, completely dead, no humming or any sign of life. Was easy to use and I liked it, but it just plain died, or so I believed. Decided to plug it in one more time before junking it, and to my amazement it started working. Perfectly again. It seems there must be a thermal protection switch inside, and it has a LONG COOL OFF TIME before it will turn on.From now on I will let the motor cool off for about a minute, with no load, so the thermal switch does not kick in.

I did not have any experience with this type of sharpening tool. I used it successfully to sharpen my dull chainsaw blade. However, I am unsure of how long the sharpening bits may last, and I am also unsure of if this type of electric sharpener may lessen the life of the chain because the results depend entirely on the skill of the user. Perhaps a more precise tailor-made sharpening tool (even a manual one) will help the chainsaw chain provide more service life.

I have had my EzzDoo for 3 years. I live on 20 acres and we cut a lot of trees. We rotate 10 blades and sharpen them all in sitting when they are dull. This little grinder keep them very sharp. It has even refurbished defunct blades we thought hopeless. The company has great customer service. After three years and hundreds of grinds our threaded locking nut wore out. EzzDoo sent a replacement no questions asked in just a few days.

I took a chance on this item and I am glad I did. I was tired of using the round files that take forever to sharpen my blades and needed something that would work without taking up a lot of time. I sharpened the dull blade on my saw and could immediately feel the difference in how it felt verses the round file sharpening. I was able to keep a good angle on the blade and the teeth sure felt sharp. The litmus test was working on my lot cutting down dead black spruce trees (which dull your chain with just a few trees). I went through dropping, limbing and cutting stove lengths no problem with the old blade that I sharpened. When the chain felt like it was cutting slow, I just quickly re sharpened it and went back to work. No problem, no wasted time, nice and sharp.Pros: Worked as stated, adjustable motor speed, sturdy storage box for the tool. Came with a few bits and wrenches.Cons: Sharpening bits will last for two sharpening cycles then are junk. Good thing they are cheap and disposable.Recommendations: As the tool comes with three different sizes of bits, figure out which one fits your saw blade the best then order a bunch more to have on hand.I was so pleased at how well the sharpening process was, how well it worked in the field and how much better it made my afternoon that I bought another kit for a gift to give away.

Easy to use, works great. Once I got the angle right. I sharpened a 20" chain in no time. I do suggest using an old chain first to practice with. I have a couple teeth shorter than the rest. It sharpens quick. I love it.

You will need to buy new grinding bits. Order them now as they are really soft metal and not very abrasive!

so bought this in june 2024, never got around to using the chainsaw till 6/25, was so dull would barely cut. So i got this out, followed the you tube video, WOW did it work great, blade was like brand new and took less than 3 minutes to do.
