Ideal for drilling anchor fixing & through holes in concrete & masonry from 12 to 40 mm in diameter. Core drilling up to 90 mm. Chain drive improves durability & increases efficiency together with an oil filled gearbox to ensure total component lubrication & superior heat dissipation. Ergonomic, compact & slim line design maximises control & offers easy access to confined spaces. Excellent power to weight ratio: 8 Joules of impact energy delivered by a 6.1kg 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 & extended tool life. Hammer mechanism is optimised by reducing the number of components & by improving dampening to deliver maximum impact energy & therefore the efficiency to drill into the hardest concrete. Efficient mechanism delivers impact blows directly to the bit without losses through excessive vibration & rebound dampening reduces stress to the tool. Soft rubber grip handles improve user comfort lowering fatigue during extended use.
