Question

Material used for cutters for drilling glasses and ceramics?

Answer 1

Steel or hardened steel, you need to shape it in a spear form. Otherwise diamond cutters.

Answer 2

diamond are the only tool material which could cut glass and ceramics.

Answer 3

*Cutting tool inserts are being made with silicon

carbide whisker reinforced alumina and TiC-Si3N4/Al2O3 because of their high chemical stability and ability to operate at high cutting speeds. In fact, cutting tool speeds have increased by a factor of 100 since the turn of the century because of the development of these new materials.

*The computer controlled abrasive waterjet will machine complex flat parts out of most materials - including metal, plastic, glass, ceramics and composites.

*Diamond tipped tools are best.

Answer 4

Diamond is used

Answer 5

masonry and ceramics can be drilled with tungsten carbide bits, either inserts soldered in, or spear shaped. masonry contains sand, so I suppose the same bit could drill glass. don't let the bit's get very hot - the solder will let go.

     I know glass can be sawn with those tungsten carbide rod saws-  spray water to keep the solder cool.
