I was using those of another manufacturer before you buy this product, but Hawatari is I have easily broken long. I checked on the Internet, because it was recommended the item, when I use, was free is spa spa and the hole without breaking at all.

After purchasing 2 packs, we used about 2 pieces, but even if you are careful with chucking to the machine you will get a blur when you rotate. I think that the drill is warped. I am sorry just because there is no problem with sharpness.
