Short lifespan

Decent bits, they tend to wear out quickly in porcelain regardless of how fast or slow they are used. Lifespan seems to be 20 holes or less for the 1/4" size.

Great drill bits to use in the grinder

I used it in the grinder to drill hard porcelain tile and the performance was really good. Very easy to use and cuts look great!
