1. The diamond drill bit is made of industrial-grade carbon steel and plated with a nickel coating to enhance the corrosion resistance.
2. The high quality diamond coating improves the hardness, sharpness and cutting speed of the drill bit and realizes a smooth, high precision cutting edge without damage.
3. The large clearance hole on the side of the drill bit facilitates the pouring of cooling water and the escape of chips during operation, making the drilling process easier.
4. The small hole above the hole cutter helps us pull out the debris stuck in the hole saw with a screwdriver.
5. Suitable for Glass, Tile, Fiberglass, Porcelain Tile, Ceramic, Slate Mable, Granite Light Stone. Not for use on Concrete.

Warm Tips:
1. Please keep adding water to keep the drill bit cool and increase lubricity during working.
2. Keep the drilling speed at 800-1000 per minute to reduce the drilling pressure, which can greatly extend the service life of the drill bit.
3. Dry drilling is strictly prohibited for this product.
4. Since the product is measured by hand, please allow a difference of 1-2 mm, thanks!
5. Our image is as consistent as possible with the real object, but due to the equipment, display and light, the color of the two is slightly different.

I used the smallest one to drill a hole for a knob on the top of a ceramic butter dish cover.

I was really impressed with these little diamond drill bits. I put a hole for drainage in a ceramic plant holder. I was worried because it’s a one off a kind, but it worked like a charm. Very easy to use. Just have to take your time.

I’ve never used a drill before- let alone drill holes in glass or ceramic! I wanted to make my own flower pots , I had to watch a diy video and followed the directions exactly! Worked amazingly! First time ever and so happy with the results !!I drilled at an angle with it turned up to the highest number. I had a little cup of water , I poured enough to cover the bottom and began. When the water got sludgy or cloudy, I would just pour a tiny bit more over that until it was clear again. Repeat the process. It never clogged and I had no problem with mess or buildup.

Needed to drill holes in several large ceramic pots. Worked well, just need to remember to stop and clean out center frequently.

Are used water as a lubricant whenever drilling holes through porcelain wall tiles. It appears that the hole saw will work well for drilling several holes. My only complaint is the difficulty in removing the material from the inside of the hole saw. It takes more time to clean it than it does to drill the hole.
