You can find them in the same sizes.
Difference between sheet metal and self tapping screws.
And they are even available in the same materials.
The most important difference between self tapping and self drilling screws is that self tapping screws cannot go through metal without a pilot hole which must be pre drilled or pre punched.
Self drilling screw points are numbered from 1 through 5 the larger the number the thicker metal it can go.
Self drilling a screw that can well self drill through various gauges of metal materials without predrilling.

Whichever name is used these names are for screws that form mating threads tapping the threads.
High low screws are specifically designed for certain plastics and other low density materials.

If the tip is flat it is thread rolling rolling or extruding threads and creating zero clearance between screw and material.
However it is also often called a sheet metal screw.
Self tapping a screw for securing thinner sheet metals and other substrates that cuts its own thread but usually requires a predrilled or pre punched hole.
Self tapping screws tap their own thread so they need a pilot hole slightly smaller than the screws diameter.
In some fields understanding the differences between self drilling and self tapping screws is essential to performing construction tasks properly.
