A sharp tip is usually for drilling into softer materials, such as wood or plastic, without having to drill a pilot hole.
What is the purpose of ASTM testing?

What are self-tapping screws and self-drilling screws?
Self-tapping and self-drilling screws can easily be confused. Self-tapping screws do not have an integrated drill bit into the screw and certain types of self-tapping screw require a pilot hole to be drilled before it can be driven into material.
Self-Tapping Screws
Blunt nose and flat ended Self-tapping screws require a pilot hole slightly smaller than the screw diameter to be created before they can be driven into the material with a screwdriver. Pointed nose self-tapping screws do not require a pilot hole.
Popular types of self-tapping screws
Allows for a flush finish as the head of the screw sits below the surface of the surrounding material. This allows for a flat finish and a smooth result.
Self-Drilling Screws
If you require Tek screws for wood applications you can use ones which are manufactured for roofing. The flute on these screws is very small and the diameter of the hole that it drills is smaller than the diameter of the outside screw thread. This design allows the screw to bite into the material for a secure hold.
Common project questions
Aluminium has many positive characteristics that make it easy to work with. When using self-tapping screws on aluminium choose a self-tapping screw with a drill like point and sharp cutting blade threads that go down the whole length of the screw.

FAQs
In most cases, trial and error will help you work out the appropriately sized screw. You should take into account the thickness of the material and the finish you require. Also, note that it is easier to make a hole bigger with a larger screw than a larger sized hole smaller.
