I would like to be able  
to drill a .25" hole through a countertop using a drill pre
ss.  I have  
only small slabs that I will be drilling, however they are ~1.25"  
thick.&
nbsp; I plan on simply running a water supply to the end of the bit  
via tubing from a faucet. The number o
f holes  I plan to drill is  
100-150.
