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 diamondsystems family. Together with the already familiar and highly successful Hilti DD 200diamond coring machine, professional contractors now have a choice of three driveunits that cover virtually all coring applications. These extremely powerful units notonly provide superior performance, they also form a simple, easy-to-use system.
Unique high-frequency motor The new coring machines are equipped with innovative, water-cooled, high-frequencymotors. Designed for the new DD generation of diamond coringsystems, these powerful new motors are rated at 3600 and 5500 watts respectivelyin the DD 350 and DD 500. This 1000 Hertz high-frequency technology not onlyachieves higher performance, it also reduces weight and cuts maintenance costsas 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 andallow speed to be adjusted while the motor is running. The built-in Iron Boostfunction provides useful extra performance for coring through rebar.
System approach for higher profitability This new generation of extremely powerful drive units makes light work of coring in diameters up to 24 in. Specially optimized for the DD 350 and DD 500 systems, the H2S and H6S line core bits feature segments with a height of 0.39 in, and a diamond matrix finely tuned to match the power output of the new machines. The continued development of these core bits has resulted in performance improvements that translate into higher potential cost savings for the customer. H line core bits feature standard 1.25-in, 7 welded connection ends for long life and trouble free operation.
Wide range of applications Drilling corner holes, penetrations for pipes and cables, large-diameter drilling, deep-hole drilling and coring in highly-reinforced concrete are only a few of the many applications for which these new diamond coring systems are ideally suited. The power controls on the drive units indicate optimum feed pressure, making the system easy to operate under a wide range of conditions. The folding DD-HD 30 drill stand, designed for use with all three DD drive units, remains rigid and secure even when set up for oblique drilling, allowing angles of up to 45° to be tackled without difficulty.
Technical superiority aside, Hilti’s new diamond coring systems are also unbeaten in terms of safety features and total cost of ownership: the clearly arranged control panel with convenient service indicator reminds the user well in advance of the need for servicing. Thanks to Hilti’s comprehensive Lifetime Service, the owner has no servicing or repair costs whatsoever during the first two years, or 200 operating hours, whichever comes first. The new DD 350 and DD 500 systems give diamond coring professionals the means to increase their competitiveness and stay ahead.
