Hi everyone nice to be here, hope I can help with questions and answer,
Hey I need to drill like about 600 holes in porcelain tile ( made by mirage) to install clothes line in bathrooms.
I use a diamond hole saw bit ( 1/4" ) and a spray bottle and on Saturday 17, I did only 16 holes and 3 bits warn out.
Is there any other way I can do this

Thanks

Speed, drill choice and coolant are going to make a big difference in the lifetime of the bit.

There is pretty good guide article on digg - Digg - The Ultimate Guide To Drilling Porcelain Tile (http://digg.com/educational/The_Ultimate_Guide_To_Drilling_Porcelain_Tile)
