special hole feature

Hello everyone,

I am new to Solidworks and Im trying to create one specific part with some special hole bud I dont know how to create it.

It is hole, but I cant create it with hole wizard. And when I create it as extrude cut it is very hard to get position of this. I need more than 5 this holes on various faces on part and I am finding best practice how to create it.

Thanks for all replies and helps
