Description
Ejecución:
- Versión larga o extralarga.
- El extremo delantero de la prolongación está configurado como pinza portapieza. Al apretar manualmente la tuerca de apriete moleteada se sujeta el macho para roscar con la pinza portapieza.
- La transmisión del par se produce a través del cuadrado.
- El extremo posterior de la prolongación corresponde a DIN, de forma que la prolongación se puede alojar en insertos de cambio rápido de macho para roscar o pinzas portapiezas ER de macho para roscar con cuadrado.
Con alimentación interna de refrigerante.
Aplicación:
Para tallar roscas en puntos inaccesibles, p. ej., en escotaduras profundas, rebajos, cantos de interferencia en dispositivos, roscas interiores situadas a profundidades extremas o directamente en paredes de fundición.
Nota:
Pinza portapieza hexagonal alternativa para la fijación del macho para roscar disponible a petición.
