Can i drill small holes in a glass jar with these?

These diamond bits arent made to drill on glass they are used to etch on glass. To drill holes on glass you need a carbide bit and make sure you constantly keep the bit wet by spraying with water or anti freeze while you drill so you dont damage the bit and also so that the glass doesnt get too hot and end up breaking

can these drill bits be used to put a hole in gemstone or are they just used for etching?

I use the 1&2 mm to drill my stones. I also purchased 30 box of all 1 mm,for drilling...

Can I cut slots in in weld epoxy with these ?

I do not expect this drill to cut from its sidewall for hard material. For softer material, it could work.
