Excellent power to weight ratio: 8 Joules of impact energy delivered by a 6.1 kg hammerIdeal for drilling anchor fixing and through holes in concrete and masonry from 12 to 40 mm in diameter. Core drilling up to 90 mmChain drive improves durability and increases efficiency together with an oil filled gearbox to ensure total component lubrication and superior heat dissipationErgonomic, compact and slim line design maximises control and offers easy access to confined spacesRotation-stop for medium-light demolition applicationsUnique dust sealing protection to prevent even the finest dust ingress into the hammer mechanism delivering high durability and extended tool lifeHammer mechanism is optimised by reducing the number of components and by improving dampening to deliver maximum impact energy and therefore the efficiency to drill into the hardest concreteEfficient mechanism delivers impact blows directly to the bit without losses through excessive vibration and rebound dampening reduces stress to the tool
