Problem with Bool tool

Have a nice day, everybody.
I wanted to create a hole using BoolTool with the help of a spiral. when I use this function the spiral will change, but the holes according to the shape will not be created. I have converted the spiral to Mesh.

Here is a link to download the Blender file:

Thank you for help.

Hi, close the caps (open endings) on the spiral.

P.S: You have a really high polycount count for that single objects.

You are absolutely right about the number of polygons. I’ve tried everything possible. Thank you so much for helping me.

Sooo, did closing the caps helped?

You were right. I overlooked that little detail. Everything’s fine.

Please, mark it as solved
