Boring bar used for milling

I'm having troubles with using boring bar for making a hole with tight tolerance in cnc milling proces. When I choose my setup and select Drill operation and then for cycle type Boring or Fine boring, a boring bar won't move to the end of a hole, it only goes straight up and down without touching the end of a hole. Boring bar's diameter is 18 and hole's diameter is 35 H8 (+0.039/0) [mm]. I have been struggling with this for a while now and really can't find the answer.
