Review on 💎 Diamond Drill Bit Set by Neiko: Superior Performance for Precision Drilling by Jacob Sriubas

I bought these bits to make several tiered tea services. This was my first attempt at drilling pottery, china and china, so I didn't want to buy anything expensive. They work damn well. I read many reviews about the diamond coating that shows on first use. For me this isn't the case, although I will say you have to use water to keep the racquet cool and that makes a huge difference. I was disappointed they didn't fit my dremel so I had to use a regular drill bit but it worked really well. They are inexpensive but work quite well. I'll use the larger bits later to make some of the lamps.
