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

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.

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

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.

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.

Just what my husband was looking for.

Great Product

I used this with the Dremel chain saw sharpener kit to sharpen my Stihl electric chain saw. The saw cuts very well after sharpening and the sharpening tool shows no noticeable wear.

These are great for sharpening chainsaw chains. Used the stone ones for a short time but they were easy broken. These are well worth the money!
