Abstract
A lamina-shaped borepiece (4) for a self-boring fastening element (1) is provided at its front side with cutting edges (5,6) flanked by grooves (7,8) that extend approximately parallel thereto. Indents (9,10) with set-back cutting edges (11,12) are provided in the area of both front cutting edges (5,6), so that a kind of stepped borer is created. The indents (9,10) are formed in the area of the axial extension of the grooves (7,8).
