the hycon hcd 50-200 handheld core drill shown here for drilling ranges from 5 to 35 cm and weighing only 7.6 kg, impresses in terms of both security and economy. the drilling is done by hand. extensive assembly work on a drill stand is not needed. within 104 seconds, the drilling operation shown with a bore diameter of 200 mm was completed. theoretically, up to 34 holes would therefore be possible within an hour. the hydraulic drive minimizes the machine's own vibrations and thus leads to a doubling of the durability of the crowns compared to gasoline-powered core drilling. the speed of the handheld core drilling machine can be continuously optimised for each drilling range.for this purpose, the amount of oil to the power unit
is continuously set to the optimum value.thus, a maximum drilling rate at minimum cost is guaranteed.the core drill is suitable for both dry and wet drilling. using an adaptor, all conventional drill bits can be used. for further drilling, the retaining ring can be continuously adjusted up to 360 degrees.the operator can thus be in control in any position triggered by the machine torque. before the operator can jam the bit deliberately now, the engine speed is optimised.in addition to optmised hand and grip bars, the core drill also has a virtually instantaneous safety shutdown.
these safety shutdown ensures that if the drill bit jams, neither the operator can be injured nor the drill bit damaged. once the drill bit is not blocked any more, the drilling will be continued immediately without further loss of time. the drill bit is intentionally jammed by the employee within a good 13 seconds. it is apparent that the drill bit stops immediately. the deliberate canting is accurately maintained for 2 seconds. after the canting, the core drill starts up immediately and in controlled fashion. at no time is there any danger to the operator. the safety shut-down shown is wear and maintenance free. this minimizes the maintenance costs
in a decisive way.the machine is 100% emission-free making it 100% safe to use in trench shoring. the hydraulic drive also excludes hazards and damage caused by electrical short circuit both for the operator and the machine. wet drilling even "overhead" or underwater is 100% safe. furthermore, the drill bit will be blocked by the operator via intentional tilting. the machine stops again immediately and starts up again after the end of the canting, in a gentle and controlled way. this leads to maximum security with maximum economy. the hand-held core drilling machine is also part of our efficiency box. you can test them as part of a short- or long-term rental for their reliability and
efficiency. of course, you can always purchase them from us at any time.
