Both the ARBOGA A2608B bench drills and the power-feed version A2608M are gearbox driven for increase drilling torque. Helical and steel gears ensure highest operational efficiencies for a more powerful drive mechanism and smooth operation. On the Arboga A2608BM model, once the set drill depth is reached, the spindle will automatically return to the starting point. The feed gearbox is fitted with automatic overload protection which intervenes if the drilling pressure is too high.
