How do I make a hole in an object created by me? Please help, youtube tutorials didn't help at all. Hope the image help.

$\begingroup$ It's not entirely clear to me exactly what you're asking. Is this for use in a game situation, or in an animated film? My first impression is that you want the (moving) pick head to create a hole in the tube object during an animated sequence. If that's not what you intend, perhaps you can edit your question to make things clearer. $\endgroup$ – brasshat Sep 9 '14 at 16:05

You could use a couple different methods:
Boolean modifier:
Add a boolean modifier on the object you want to cut a hole in,
Create an object to "subtract" from the main object
Set that object in the boolean modifier. You can press E while hovering over the object selection field to set the field by clicking on an object in the 3D view.
knife project tool:
Add a circle or some other object to define the outline of the hole
With the circle selected, ⇧ Shift select the object you want to cut a hole in and enter edit mode (↹ Tab)
Select the faces you want to cut, then click knife project in the tool shelf. If you want to cut all the way through the mesh, enable Cut through in the redo panel (F6)
Then select the newly cut edges with ⎇ Alt⇧ Shift
RMB and press W> Bridge edge loops to connect the ends of the hole.
Face intersect tool:
This feature will be added in 2.72, but until then you can use it in the latest development builds.
This is essentially like the boolean modifier, except it works in edit mode.
Here is a nice video made by the author of this feature, explaining how it works.

$\begingroup$ @gandalf3 +1 Never new about the intersect tool! $\endgroup$ – GiantCowFilms Jan 26 '15 at 14:05

$\begingroup$ @gandalf3 I try to understand your booelan method. But I don't understand what you mean with "You can press E while hovering over the object selection field to set the field by clicking on an object in the 3D view." ?? $\endgroup$ – Old Man Sep 24 '15 at 11:22

$\begingroup$ @JanScherders By "object selection field" I was referring to the place were the Cylinder object is specified in the boolean modifier. You don't have to specify the object by pressing E, but with many objects in can be easier. $\endgroup$ – gandalf3♦ Sep 24 '15 at 20:00

For 2.8 join the two object together then in Edit Mode select the object you want to make the cut (hover object and press L ) Face Menu > Intersect, should be half way down the menu

$\begingroup$ Could you elaborate on 'join the two objects together'? $\endgroup$ – spuder Dec 27 '20 at 5:47

You can also use curves for modelling the base mesh.then use the curve with edit mode then add a bezier circle to make a hole.

10$\begingroup$ Sorry for bumping, but those steps are indescriptive, unclear, and mainly wrong. Fix them. Where on Earth would adding a Bézier circle create a hole instead of just adding.... a circle? :P $\endgroup$ – Gustavo6046 Aug 26 '16 at 22:08
