Abstract

Die Erfindung betrifft Meißel (10), insbesondere Rundschaftmeißel mit einem Meißelkopf (13) und einem Meißelschaft (11), wobei im Bereich des Meißelschaftes eine Befestigungshülse (20) gehalten ist und mit einem Stützelement (30), das einen Führungsbereich (36) aufweist, wobei das Stützelement an seiner Unterseite einen vorstehenden Zentrieransatz (34) aufweist.The invention relates to chisels (10), in particular round shank bits having a chisel head (13) and a chisel shank (11), wherein a fastening sleeve (20) is held in the region of the chisel shank and having a support element (30) which has a guide region (36) wherein the support member has on its underside a projecting spigot (34).

Eine verschleißoptimierte Meißelkonstruktion ergibt sich dadurch, dass der Zentrieransatz (34) eine zur Mittellängsachse des Meißels (10) geneigt verlaufende Zentrierfläche aufweist, die über eine zurückversetzte Ausnehmung (35) in eine radial zur Mittellängsachse verlaufende, umlaufende Seitenfläche übergeht.

Figure imgaf001
A wear-optimized chisel design results from the fact that the centering projection (34) has a centering surface inclined to the central longitudinal axis of the chisel (10), which merges via a set-back recess (35) in a circumferential side surface extending radially to the central longitudinal axis.
