Description

Eccentric Adapter for U Drills, Eccentric Sleeve for Indexable Insert Drills

Eccentric Adapter for U Drills, Eccentric Sleeve for Indexable Insert Drills is the adapter sleeve for the eccentric mounting of indexable insert drills in tool holders with a larger mounting diameter. The eccentricity allows the bore diameter to be adapted to the machine requirement.

The eccentric mount enables bores with a larger diameter than the indexable insert drill originally provides – by shifting the bore axis by the eccentric value, the bore diameter can be set steplessly. The hardened steel body ensures a backlash-free interface, and clamping in the tool holder is performed with standard clamping screws. The adapter is compatible with the common indexable insert drill interfaces.

For the flexible adaptation of bore diameters on indexable insert drills, the eccentric sleeve is the specialised adapter solution with clear tool modularity. The construction is designed for reproducible bore dimensions and predictable change cycles.

Exzenterhülse für Wendeplattenbohrer

Mit der Hülse kann ich den Bohrer feinjustieren und den Durchmesser bei Bedarf anpassen. Funktioniert zuverlässig, kein Spiel nach dem Spannen. Gerade bei Sonderdurchmessern eine saubere Lösung, statt einen neuen Bohrer zu bestellen.

Gute Spanabfuhr

Hat meine Erwartungen erfüllt. Ordentliche Standzeit. Im Alltag spart das einiges an Nacharbeit. Spanbruch passt bei mir gut. Werkzeug bleibt bei mir im Einsatz.

Exzenterhülse tut zuverlässig Dienst

Exzentrischer Adapter für leicht verschobene Bohrungen. Spart den neuen Bohrer in mancher Reparatursituation. Sinnvolle Ergänzung für die Werkstatt, praktisch bei Wartungs- und Umbauarbeiten wo das genaue Bohrmaß nicht immer vom Werkzeug selbst vorgegeben werden soll. Gut verarbeitet.
