Review on 💎 Diamond Drill Bit Set by Neiko: Superior Performance for Precision Drilling by Robert Carter

It took us 2 people to do our job. One drilled, the other sprayed water to keep the drill bit from overheating. hollow. Gives this does the material have room to move and I think creates less dust? On the other hand, it's harder to get in. Without a sharp tip (which wears out quickly) bits tend to wander. To get around this, we started by holding the bit to one side (20- degree angle). This brought a smile to the china, later combined with a frown from above to form a circle. Once this was done, the bit could be held forward - set in marks. After the first whole was complete, my handyman was called in and he quickly did the rest I think it took about 20 minutes to drill the remaining 5 holes I double checked the drill with mine n fingers to make sure it wasn't too hot. Barely warm. I sprayed constantly and didn't even use half of the large squeeze bottle. I used the middle club to make 6 holes and I believe the club has enough life to make at least 6 more. The bits were filled with tile/water paste and difficult to remove. It happened twice. Each time I added another 5 minutes to the work.
