What kind of drill bit is this? Can it be used to drill a hole in concrete?
EDIT: after the accepted answer provided me with some details I found out what it is. Details here, on page 5. And the answer is yes. It can be used on concrete.

Two tell tail signs point to a masonry bit. The shape of the cutting teeth and the fluets on the shaft. That is certainly a masonry bit. Look like a design typically used on an SDS plus bit. If so, that's another determining factor.
