Frillylily, if you don't wet the area while drilling, it'll wear out the drill pretty quickly.
What I do it is fill up an old "sports" water bottle (with the flip top) like Poland Spring and squeeze water onto the contact point while I'm drilling.
btw, I'm a big old weakling with no upper body strength, and I found this to be very easy!
Oh, and I didn't purchase the drillbit from that website. That was just to show you what it looks like. I found one at HD pretty easily.
