Fantastic little set. Sturdy case and great drills. I had to cut a hole for my bathroom sink and it worked very well. Just make sure to keep it wet and go nice and slow! I also always try to clamp a wooden piece with same size hole on the porcelain so there is no spinning and you have a great guide.

Wide range of hole saws in this kit held neatly in place in the included carry case. My experience with these Chinese made diamond products is that they work quite well and are often priced quite reasonably. Even if they claim to be 'no water needed" bits, it is always best to use water to keep the bit cool and preserve the life of the bit. Dry drilling in these types of products produces an incredible amount of heat which can result in heat stress/fatigue of the tool itself. Overall, a good value.
