Query: Spend your money on a better set.

There are some true running bits in this set but too many of them wobble way too much. I'm talking about the first time being used too. the initial spin makes a wobble so big that you can't hold the object being drilled. you need to loosely hold the item so it wobbles with the bit to get a hole close to the bit size. Cheap but not worth the expense of my projects. i'll look for a better set.
