As you can tell on this picture is this the way they are supposed to look like?
I use what I call a 'Bit in a Stick' turned by hand. In your case you do need a 1/8" drill bit.
You also can find some square shanked drill bits that you can insert in a 1/4" screw driver handle..
This group of pics shows basically what Lemoyne was talking about...
