SCREW

The invention relates to a screw (1) having an end mill (7). In order to reduce a screw-in resistance of the screw (1), the invention proposes that the end mill (7) have two successively arranged sets (9, 11) of milling ribs (10, 12), of which the front milling ribs (10) are in the opposite directio...

Zusammenfassung:	The invention relates to a screw (1) having an end mill (7). In order to reduce a screw-in resistance of the screw (1), the invention proposes that the end mill (7) have two successively arranged sets (9, 11) of milling ribs (10, 12), of which the front milling ribs (10) are in the opposite direction to and the rear milling ribs (12) are in the same direction as the screw thread (8). Both sets (9, 11) of milling ribs (10, 12) have, in terms of magnitude, a greater pitch than the screw thread (8) and the milling ribs (10, 12) transition into one another in a V shape.
