Like everyone said these are great beats. They did a very good job cutting holes in the granite for the dressing table. I wasn't aware of this when I bought it, but thought it might be worth clarifying for everyone else: THEY ARE NOT DEPTH ENOUGH FOR 3CM GRANITE. They're really close, but it won't go completely away. Since I used two large bits for the sink and faucet hole, I was able to use smaller bits to break off enough of the "inner" hole to cut the rest of the way with the large bit. Still 5 stars for me as you can't beat the price and it worked out in the end, it just needed some persuasion.
