Inditrust 5pc 8mm Heavy duty Ceramic Glass, Ceramic and Tile Drill Bit set

Decent product, it does cut holes very well on tiles ,almost any type, And probably glass too with ease . But do know that these types of drill bits work as self destructing, meaning a bit won't last for long and eventually get worn off with around 10-15 holes. But imo. it may last longer if it's used carefully only to cut the tiles/glass alone, without touching the cement/concrete below.
