Abstract
Perfeccionamientos en dispositivos punteros para máquinas rozadoras, taladradoras y similares, especialmente para máquinas de arranque y de extracción, con un puntero cónico que con un vástago del cilindro es insertable en forma giratoria y recambiable en un taladro de alojamiento cilíndrico de un portaútiles, y que está asegurado contra desplazamiento axial en el taladro de alojamiento cilíndrico de un portaútiles, y que está asegurado contra desplazamiento axial en el taladro de alojamiento mediante un anillo de seguridad elástico dispuesto en una contracción del vástago del puntero, caracterizados porque el anillo de seguridad se dispone en un anillo cojinete dispuesto rotativo en la contracción, del vástago del puntero y consta de un anillo deformable, especialmente un anillo tórico, que se presiona contraunión por fricción contra la pared cilíndrica del taladro de alojamiento.
