Wide range of usages:
Our ceramic diamond core drill adopts vacuum brazing technology, so the drill can cut harder materials at higher temperatures. It is very suitable for drilling clean holes in similar materials such as granite, ceramics, glass stone tiles and marble tiles (not suitable for wood)
When decorating kitchen or bathroom walls or fixing mirrors or installing showers in bathrooms, you need to drill holes in mirrors or tiles without cracking them, so you need to use these diamond drills to make these holes very accurate
Specification:
➤Color:blue
➤Material:carbide
➤Shank Type:Round Shank
Steps to drill clean and precise holes:
1. Place the drill at a 45 degree angle, so the drill has the chance to start and will prevent the drill slipping
2. Slowly move the drill bit into a more up-right position and Continue to drill and swaying the machine along a circle
3.You don't need to apply too much pressure to let the drill finish the work. Once the drilling is completed, you will feel the drill break through the back of glass or ceramic tile
4. Be careful when using, because if you use it too fast, it may burn a little glaze and burn out

I bought these to install hardware in a finished tiled shower. I drillled 4-5 practice holes though waste pieces fairly well, but by the time I got to the shower, the 6mm bit was dull. I was able to start the holes, but the bit would not cut after that. Maybe I ran it it too fast - I started slow and sped up to 1650 rpm, the max on my variable speed drill.

Pros and amateurs alike, cannot stress enough the need for WATER while you drill. Otherwise terrific bits, drill clean holes with minimal stress fracture

Good price did the job in a resin quartz counter top. Cut right through just make sure you apply pressure and high speed.

I had to drill sixteen 1/4” holes and other bits I used failed. I ordered a 10 pack of these and only went through two bits. They saved me a lot of time and money. After other diamond bits I used wouldn’t go through the porcelain tile I figured I had to order a ten pack to drill the 16 holes I needed. But only had to use two of the ten bits. Excellent purchase.

I bought these dry diamond bits to drill drain holes in the ceramic plant pots.They worked decently enough, but obviously are not going to last long.After three holes, the diamonds were worn off the 12mm bit.If I needed to drill holes more often, I'd spend a few more buck on better quality bits.
