The power transfer from the motor to the cutting blade occurs without friction. The brilliant advantage: Completely independent of the battery's charge level or hair density, the ER-1611 cuts with consistently constant force. This allows you to work faster and more safely. Additionally, the carbon fiber and titanium-coated X-taper Blade cutting blade ensures a razor-sharp and thorough cut in both dry and wet hair, whether for fine contours or complete machine haircuts. The combination of diamond steel and titanium hard coatings provides double the durability compared to conventional stainless steel and ensures permanently sharp blades. Precision cutting with a 45° edge, six cutting lengths with three comb attachments, a suitable charging station, a remaining capacity indicator, a charging control light, and a rotary dial for adjusting the cutting length of the scissors blade, precisely adjustable from 0.8 to 2.0 mm.
