Abstract
Cette pointe permet un réglage rapide et précis du parallélisme de la pièce à travailler. A cet effet, l'extrémité conique utile de la pointe possède une excentration par rapport à l'axe géométrique de l'ensemble de la pointe, de sorte qu'en modifiant la position angulaire de l'ensemble de la pointe, on fait varier la position dans l'espace de l'axe de l'extrémité conique utile de la pointe. L'invention s'applique aussi bien aux pointes tournantes qu'aux pointes fixes
