Exactly, and if it is thick you are going to clog the debris channels pretty quickly. This means you will be forced to remove the tap completely and clean it out, re-lube it up, and go in again. Be careful with a T-handle: you can put a lot of torque on a tap, a bad thing with a smaller tap. This means you have to "feel" the tap and look at it to be sure it isnt flexing. If you see much flex, back off and try again. Also, if you get stuck and the thing is jammed in there and wont go any farther, back it off and drill it again: you might just have something stuck in there.
And yes, using larger bits does work as long as the holes do not need to be blocking water or holding a signinficant load.
