It's nice to live in a perfect world, isn't it? Where everything goes according to plan, where you don't have to figure things out, and where everyone does it YOUR way.

Welcome to reality, pal.

I don't understand.

What is the difference between a masonry bit and a bit for a hammer drill?

(I do not think you are referring to SDS.)

This is probably a country specific terminology thing then...

(I take it you are not in the UK?)

In UK terminology, the masonry bit pictured by the OP would be used in a conventional "hammer drill", but not a "SDS Drill", or "Rotary Hammer".
