I need to fit a blind to a window recess tiled with porcelain tiles which means drilling two holes upwards into the top side of the recess.

I have the set of drills from 365 Drills but don't see how I drill upward and keep the drill tip cool without a whole lot of water running down into the drill.

Any ideas guys?

You might have to get a hand, someone to spray water on the drill bit with a spray bottle. Or just drill a little bit befor quenching the bit in some water then repeat the process until the hole is drilled.

Thats what I would do in that situation I think

Yep, agreed. I never hold a sponge or anything against my drills. I just stop every now and then to dip the drill bit in my bucket.

Thanks for the replies guys!
