Review: Für kleinere und weichere Materialien hervorragend geeignet. Bei dickerem Blech allerdings Probleme, aber dafür ist der kleine ja auch nicht gedacht.
Review: Il prodotto è buono, consiglio l’utilizzo sull’alluminio rispetto all’acciaio dato che riesce a fare buchi più profondi rispetto al secondo, però comunque è tranquillamente utilizzabile con l’acciaio
