[modeleng] How do they make that?

In idle moments I often look at domestic items and consider how I would make 
them with the equipment at my disposal.
(Lids for jam jars would be fun!)

Take a look at these drills,

Unless they have a corkscrew shaped drill, the only way I can think of 
making them is to drill the coolant holes, and then twist them to shape.

Anyonw know this, or have any better ideas?
