Integra Tools 7/32" Diamond Chainsaw Sharpener Burr 1/8" Shank, 6 Pack

Works much better that stones for sharpening chains. Has sharpened mine about 10 times and still using the same bit, but it is starting to wear down a bit. Works faster than stones as well. Will buy again when needed.

Great Product

Used my first bit to sharpen my chainsaw blade. The previously dull chain now tore through that wood as well as it did when it was new. And I could see no wear on the bit at all, unlike the stone bit that came with my Dremel. These should last a good while.

I sharpened my 20" chain saw blade (while the blade was on the saw) and these in conjunction with my multi-speed Dremel tool worked great. I went from a, not work a heck blade with more smoke than wood chips, to, a hot knife through butter blade! I would assume that the a pack of six sharpening blades will last for quite a few sharpenings, at least 15+. Make sure you order the correct size sharpener for your blade.

They work as well as sharpener costing 3 times less than others my husband has used. Great buy and will buy them again when needed.

Happy with the product, just use a light lub to keep it from cloging up....

Wear out, lucky to get one sharping out it. No I do not recommend these, waste of money.

works great with my Dremel tool for sharpening my chainsaw blade, precise work in half the time of a file
