Both of these tools offer impressive, untiring performance and a set of highly effective safety features. Thanks to their rotatable grip, applications of all kinds can be tackled comfortably. “ATC Active Torque Control” ensures maximum operating safety by cutting power to the motor in a fraction of a second, thus stopping the tool when the disc shows any risk of sticking. “AVR Active Vibration Reduction” and the sturdy “DC-EX 230” dust hood make it possible to work comfortably, safely and virtually dustless when a vacuum cleaner is connected. Power input is controlled electronically by “Hilti Smart Power” for constantly high cutting performance.
