Ideal for drilling anchor fixing and through holes in concrete and masonry from 12 to 45 mm in diameter. Core drilling up to 100 mm. Chain drive improves durability and increases efficiency together with an oil filled gearbox to ensure total component lubrication and superior heat dissipation. Ergonomic, compact and slim line design maximises control and offers easy access to confined spaces. Active Vibration Control system incorporating a floating rear handle and 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 and extended tool life. Hammer 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 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. Electronic variable impact energy/speed for total control with smaller bits and light material. Lock-on switch for greater control when in chipping mode. Electronic service and brush wear indicator identifies when brushes need replacing and product should be serviced. Excellent power to weight ratio: 8 Joules of impact energy delivered by a 6.8 kg hammer. Magnesium housing for lower weight and excellent durability.
