YaeTekElectric Chainsaw Sharpener Chain Saw Grinder 4800RPM Bench Chainsaw Sharpener Grinder Wall or Vise Mount Chainsaw Sharpener Tool

I needed a good solution to sharpen my chainsaw chains while cutting down a tree and dissecting it's stump. Hand-filing the chains would have added an extra day to my work, whereas with this I can quickly set my tooth angles and amount to grind off. Can work through 2x chainsaw chains in under 5 minutes.It does take a bit more material off the chain that a traditional manual filing, but considering how much time it saved me, I would be willing to buy more chains when the teeth get too low. So far I've sharpened my two chains a combined total of 5 times and they chew through wood like there's no tomorrow. Definitely worth the money so long as the motor lasts.I just temporarily clamped mine to my workbench so that I can store it out of the way when not needed or you can permanently bolt it to a surface for continuous use.

It is way better than I expected. And can’t beat the price.

I'm in the process of clearing land for a new house build and needed a way to sharpen my chains more efficiently since I have 10 chains and I needed to be able to rotate them out as they get dulled. By no measure is this unit a commercial sharpener. If I were a tree expert/business, cutting down trees every day then I would look for a better sharpener. That said, it definitely is a big change from a clamp on, file sharpener. Once set up I can do a whole 20 inch chain in 7-10 minutes. So, if you are looking for something for just around the house sharpening then this will fit the bill and for not a lot of money.

This thing its very cool and very easy to use ! cool

It took some adjusting but I finally got it set right. I didn't expect much for a cheep sharper. I've ran several chains through this with mixed results. It is definitely a learning curve.

Nice little sharpener it is durable plastic and simple to use I was shocked at the quality of it compared to price. I own a farm so I’m running a saw pretty often and have been pleased with the sharpener I would recommend it

I was sort of skeptical before I bought this, but after using it now several times I think it works very well. It is quick and easy to use after you set it up initially. I am surprised how quick I can sharpen a chain versus the manual filing method.
