  • Excellent power to weight ratio: 8 Joules of impact energy delivered by a 6.1 kg hammer
  • Rotation-stop for medium-light demolition applications
  • Unique dust sealing protection to prevent even the finest dust ingress into the hammer mechanism delivering high durability and extended tool life
  • Hammer mechanism is optimized by reducing the number of components and by improving dampening to deliver maximum impact energy and therefore the efficiency to drill into the hardest concrete
  • Efficient mechanism delivers impact blows directly to the bit without losses through excessive vibration and rebound dampening reduces stress to the tool
  • Soft rubber grip handles improve user comfort lowering fatigue during extended use
