Ideal for drilling anchor fixing & through holes in concrete & masonry from 12 to 45 mm in diameter. Core drilling up to 100 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. Active Vibration Control system incorporating a floating rear handle & damped side handle to reduce vibration. 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. Electronic variable impact energy/speed for total control with smaller bits & light material. Lock-on switch for greater control when in chipping mode. Electronic service & brush wear indicator identifies when brushes need replacing & product should be serviced. Excellent power to weight ratio: 8 Joules of impact energy delivered by a 6.8kg hammer. Magnesium housing for lower weight & excellent durability.
