We have tried several of these bits and while they cut very well they all break within a few hundred inches of use. Saving a few euros doesn't make up for poor quality. We ran a second one at a much slower feed rate to see if we could go over that and get the same results. Spend $10-20 more and get the best solid carbide hole saw. Lasts 4 times longer.
