The absolute best.

Did I show you them at ELEX or did you already know about them? I cannot
remember.

Also they do not fly through the hole you have just cut as they have a
wider diameter base than the hole you have cut.

Both CK and Starrett now have similar (first links I could find)

Its worth noting that they fit impact drivers (the Armeg one does) which
are usually smaller than a cordless drill if space is tight.

Usually when cutting into a DB or trunking full of cables I use the
floorboard lifter as protection against against the hole cutter causing
any damage.
