Use the correct speeds and feeds

Drilling Speed and Feed Calculator

chuck the drill as short as possible. ( you can hold on by the flutes )

it is very hard to generate enough feed pressure / rate with a hand drill so you likely need to slow the rpm down so that the drill makes a chip, not dust. A little bit of cutting oil will help a lot too.
