The spoon type with a lead screw, as the one you show, was often used in large mortise and tenon work. The auger removing a lot of the pocket and then chisels to square the mortise. The T handle and other pointy blade next to that in the linked picture are of your type.

Smaller modern mortising drills have a twist drill within a square tube acting as a four sided chisel. Large scale post&beam work is still often done the old way with a spoon auger. With wooden boat building, the round pocket in the beam, with pegs holding the planks.

Cheers
