This is concrete drill bit, normally its stainless steel, the tip is comparatively wider and look blunter than the other drill bitsother drill bits like wooden or metal drill bit.
While the plastic tube you talk about is call "plastic anchor".
You could use anchor bolt instead of plastic tube, go to Homedipot or Rona, the hardware section have very detailed explanation.

use hammer drill and masonary bits. Beisde the "plastic thing" you mentioned( this is called "anchor"), you can use Tapcon screws.
