Perfekt, amortisiert nach den sechsten Sägeblatt

Wir haben den Adapter für unser neues Bosch Multi-Cutter gekauft.
Der Adapter ist perfekt und zahlt sich bereits nach den sechsten Sägeblatt aus (Unterschied Original Bosch, China-Noname)
Die Kommunikation aus Deutschland war auch problemlos :-)

Multitool Adapter für Bosch GOP 12V 28

Ich habe das Multifunktionswerkzeug GOP 12V 28 von Bosch mit Starlock-Aufnahme.
Um mein altes Zubehör mit OIS-Aufnahme zusätzlich verwenden zu können benötigte ich einen Adapter, den Bosch natürlich nicht anbietet.
Der Adapter ist sehr hochwertig, massiv und stabil gefertigt. Er passt perfekt und erfüllt jede Anforderung für eine Werkzeugaufnahme ohne Starlock.

Does the job
