When purchasing decision for me the exchangeable drill chuck was decisive. The SDS recording are obstacles such as small stones in the concrete no chance, the drill rotates without pity and continue thanks to strong percussion This involves continuously in the depth. The normal keyless chuck is very accurate, at least in my machine and allows precise working in wood. Also for boaters or Forstner bit larger diameter, the machine is strong enough in softwood. Only, however, you realize when drilling very large holes with the Forstner bit (10cm diameter spruce) that the machine comes to their limits. However, I am completely satisfied and my DIY project could implement (a wine rack with self-drilled holes) perfectly with this machine.
