Swept Cut Tangency Problem - replicating a 4th axis cutter

Hi,

 

 

I am try to create a swept cut, I have had plenty of experience using this feature to create threads, however this operation is different.

 

 

It is a 5mm diameter cut (created with a 5mm slot drill) with a swept entry.

 

 

I am having trouble getting the sweep to mate with proper tangency with the 5mm extruded cut - here is a photo -

It should be a smooth transition, but to get this far what I have done is I created the sweep from a flat face and then put the circular cut in after. I have tried to create a profile at the tangency point, however because it is not on an exact degree I cannot get the helix to snap to it.

 

 

Any ideas would be appreciated.
