[Towertalk] what drill to use ?

[KB2HUK@aol.com (KB2HUK@aol.com)]

Hi Guys ! I am bringing a 1.5 inch pvc pipe into my house which carries the 
coax from the tower to my rig.  I have a brick house, does anyone know what 
kind of drill bit I should use or where I can get one ?  I would like to make 
a clean hole in the brick and I will continue with a wood saw to finish the 
hole into the house ..  thanks
