Oregon 28840 5/32-Inch Chainsaw Replacement Sharpening Stone

Doesn’t compare to hand filing for square filing chains, but is so much faster, at least 5 times, if not 10 times faster.

These don't last long, but do a great job of sharpening.

For an electric chainsaw sharpener, these work well. Wish they lasted longer and were more widely available in this size, but it is what it is. Will be purchasing again from this vender.

I use my chainsaw a lot! Sharpening it with these files in my Dremel tool is a quick job, and a lot cheaper than paying someone to do the job.

I haven't used the product yet but it's exactly what I wanted. Should be just right for sharpening my small electric saw

I bought an Oregon chainsaw which worked beautifully for a tree I needed to cut down. When I needed to remove the stump, the chain needed to be sharpened so I bought these sharpening burrs. I used a rotary tool to sharpen the saw teeth. The first burr lasted long enough to complete the sharpening and then fell apart. The second one not even that long. This has happened with other brand burrs as well. I will no longer use this sharpening method and just go to a metal file,

I have been using a small 5/32 rat tail file to sharpen my 4" chainsaw chains. The Oregon 28840 5/32-Inch Chainsaw Sharpening Stone is much faster and with better results.

I purchased these to sharpen my 18 inch Echo brand chainsaw with my Dremel 4000 series. Bottom line is these stones get the job done.The first time I used this brand my chain was pretty rough. I was able to sharpen the chain only once with the first stone. But, the chain cut better than when it was new. If the blade only needs to be touched up I can sharpen the chain twice with a single stone before I throw it in the bin.Thanks to these I will never sharpen my chainsaw with a file again. These little stones save me a lot of time and money when compared to replacing the chain. I have already purchase another package of this brand.
