I will be installing a flooring transition from carpet to concrete and thus drilling into the concrete. So, I am mostly concerned with answers to that type of application; although, any and all answers are certainly welcome and will be considered when choosing the best answer.

In wood applications, I drill a pilot hole 1/2 to 3/4 of the length of the screw. hard wood - and I mean 'hard' not just the species type - gets drilled deeper than softer materials.
For concrete applications as you mention, I actually go deeper than the fastener... usually about 1/2 inch deeper. Concrete fasteners work by gripping the 'side' of the hole - they dont grip at the tip, like wood screws do. Some fasteners require a certain depth - those should state that on their packaging.

Wood Screw Pilot Hole

Certainly there are drill bits and attachments that define depth.
In some measure ( no pun intended) it depends on the loaction of the hole drilled; IE: End cuts. it also depends on the stock, and the intent or assumption of a pilot hole.
Obviously many can be drilled all the way through; assuming the hardware will be larger in diameter. TOO large would defeat some of the purpose of the hardware.
As much an issue is again; the stock; and the intent. Do you intend to countersink the hardware? Will the hardware threads screw into; or PEG into a piece of stock close in thickness to the diameter of the screw?
Depth in the stock to hold the tip end of the screw is part of the equation, and in the end; the idea of the pilot hole as it relates to the thread diameter is GRABBING; while not causing undo stress to either piece of stock.

If you are pilot drilling into concrete you will want to drill a little deeper than the length of the screw because the concrete dust or very small particulates while inserting the screw will fall to the bottom of the hole beyond the screw. It gives it somewhere to go..

3/4 of the way

i go slightly less than the screw to get the last bite with the screw.

either i always do the whole length so u don't round off your screw head
