Problem in Creating a split point on Catia v5
(OP)
Hello everyone,
I'm currently designing a drill bit on Catia v5, but I don't manage to complete the last step I want to do, which is creating the split point (135°, 4 facets). For the angle it is okay, but I don't manage to create the 4 facets. I'd like to do something like that:

And for now I've only got that:

But I don't find a way to create the split point. I tried some things such as creating a new sketch in a perpendicular plan (to the tip surface), but nothing worked. I tried to generate a revolution but wasn't working, either it pass through the drill bit, or it goes over the edges randomly.
Does someone have an idea? A tip?
Thanks for your help, I hope someone will be able to help me.

By angular what do you mean? Which angle are you talking about?
Thanks very much

Create a line from drill bit tip to a location on the edge (I use extremum point):
Create a Sweep Surface using the line as Guide Curve and the conical surface as Reference:
extrapole in 3 direction (not the edge from the line):
Symmetry twice (or rotate 180deg) and join (uncheck Check Connexity):
Trim with the drill bit surface:
You better check real drill bit geometry but I am confident something like that could help you.
