Pick having a supporting element with a centering extension

A pick holder for a tool system, the pick holder comprising:

• a base part having a pick receptacle defined therein, the pick receptacle having a longitudinal central axis and an inside diameter;
• a wear surface defined on the base part and surrounding the pick receptacle;
• at least one extension projecting beyond the wear surface;
• and
• an end of the pick receptacle adjacent the wear surface including a centering receptacle extending in an inclined manner relative to the longitudinal center axis and transitioning directly or indirectly into the wear surface, the centering receptacle having a centering height measured parallel to the longitudinal center axis, the centering height extending between an end of the centering receptacle facing away from the wear surface and a maximum point of projection of the at least one extension, a ratio of the inside diameter of the pick receptacle to the centering height being less than 8.0;
• and
• wherein the pick holder includes a rib receptacle formed in the wear surface and surrounding the centering receptacle.
