After drilling you should have a plug inside your hole saw from the wood you just cut, this plug can be easily removed by inserting a screwdriver through one of the openings in the side of the hole saw and working it out. If your work was clamped properly, and you used a sacrificial board underneath, you should have clean holes in your wood.
