DD 350 and DD 500 Coring Systems5-Feb-2010
The Power to Put Construction Pros Ahead
The new DD 350 and DD 500 Coring Systems from Hilti give construction professionals the power to increase diamond coring productivity. These new coring systems represent a significant extension to Hilti’s diamond systems family. Together with the already familiar and highly successful Hilti DD 200 diamond coring machine, professional contractors now have a choice of three drive units that cover virtually all coring applications. These extremely powerful units not only provide superior performance, they also form a simple, easy-to-use system.
The new coring machines are equipped with innovative, water-cooled, high-frequency motors. Designed for the new DD generation of diamond coring systems, these powerful new motors are rated at 3600 and 5500 watts respectively in the DD 350 and DD 500. This 1000 Hertz high-frequency technology not only achieves higher performance, it also reduces weight and cuts maintenance costs as the motors are brushless. Equipped with 10-speed electronic gearing (E-gears), the new motors deliver a constant power output over the entire diameter range and allow speed to be adjusted while the motor is running. The built-in Iron Boost function provides useful extra performance for coring through rebar.
