I bought these for my husband to drill holes into ceramic pots for drainage. They have worked out great and so far we have not had any breakage with the ceramic pots!
You need to drill at an angle and grind a groove in your glass, then you can start tilting the bit straight to make your circle. Works great, had no issues at all going through a vintage windshield. No cracks and doesn't take too long.
Does the job it was intended to. Have only used one of the smaller sizes for a couple of holes in glass bottles but it worked pretty well. Just remember to start your hole with the edge of the bit at an angle, use a slow speed and enough water to keep the bit lubricated and be patient let the bit cut the hole.
I bought these to drill holes in wine bottles. I had never done this before but wanted to give it a whirl. These drill bits are great. I drilled a hole without breaking the bottle on my first try!
FINALLY SOMETHING THAT WORKS! I recommend this!
