Hello,
I do not know how to do this type of grooves. What is the most appropriate tool for this kind of circular grooves?
Thanks a lot for your help.
It is difficult to make this accurately as it involves a 3D cutting tool. Traditionally, the physical parts are made on a lathe with a milling attachment.
You can make a reasonable representation using the helical sweep function. You can scribe a trajectory using a wrap feature. Use the math for circumference to attain the accurate angles in a flat sketch. Be sure to add a coordinate system to your sketch!

You may also have some luck using the Offset feature.
