All drill bits have sharp ends. The reason why the tip is sharp is that it must be fixed to a member (wood) so that the bit itself becomes an axis and can rotate without slipping.
In woodworking, there are times when you need to expand a hole that has already been drilled. In this case, you cannot secure the tip of the drill bit.
This video shows how to drill a hole using various drill bits in a member (wood) that cannot be fixed.
