*by A***R on Reviewed in the United States on November 15, 2016*

Tried to drill a quartz counter top.  Would not drill it.  After several minutes, I checked the blade and found that most diamonds were gone.  Would not buy it again.

    Cuts porcelain easily
  

*by T***S on Reviewed in the United States on November 16, 2015*

Add a little water and it cuts right through Italian porcelain. It looks like it will last long enough to do 2 full bath renovations - at least.
