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

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.

I'm very pleased with this chain saw sharpener. I sharpened the entire chain within minutes right on the chainsaw. It cut through my tree like cutting butter. Be sure to order extra sharpening bits as they do wear down.

Good product, but should include a straight file and file guide to complete a sharpening. This product is easy to use. I am not a handyman or a tool guy but I would recommend this product if you use a chainsaw for five times per year.

I have never been good at sharpening a chainsaw chain. This makes it so simple. My chain has never been so sharp . It is fast and easy

A great product in a small size. It's worth the small amount to keep your chainsaw sharp. They work well on my 4 saws.

Works perfect. Fast and easy to use.

If you already have a Dremmel tool, just buy a diamond bit in the correct size for your chain.The alignment guide is just a visual gauge. You do all the work. You position the tool/gauge while trying to parallel the line on the tool to your bar. There is no hard contact between the tool and saw to hold the angle.

It works well, but the bits were pretty but didn't seem to last long. I only used 1 bit on a small 8 inch chain. It may be due to my inexperience. So I will order more bits and continue to use it.
