Take your drilling to new depths
The MDU3 is a new and revolutionary drill motor for both the smaller service jobs and the special challenges. You will always have the capacity to finish the job.
Available with a unique fully integrated autofeed motor, patented by Pentruder, or manual feed.
Product information
The Pentruder MDU3 is a versatile and powerful drilling system with a possibility to change the Drop gears in order to change the model to either MDU3-30, MDU3-60 or MDU3-100. This gives the system a very smooth and efficient run and offers a wide speed range for different sizes of drill bits.
With the quick disconnect couplings you will reduce the set up time, and if the drill bit would get stuck you can easily disconnect it and reverse the machine.
With the newly developed Autofeed small and big drill bits can be drilled in a shorter time than anyone thought possible, and when you have reached the desired depth you can choose in the setting if you want the machine to just stop, or if you want it to back up to the starting position on the track.
Pentruder MDU3 Core drill is used together with the same TS-tracks as for the Pentruder Wall saws for max stability.
Same TS-Track system as for all Pentuder machines
Famous for its high stability and easy handling. Easy to mount the machine on the TS-track. Choose between several different drill rig accessories to increase your options.
Quick disconnect drill bit adapters
Reduce the set up time, and if the drill bit would get stuck you can easily disconnect it and reverse the machine.
Patented integrated autofeed
Intuitive, easy to use autofeed - feed regulated with new-to-industry controls. Step away from the machine and let it do its job while you are preparing for the next .
Pentruder app
The Pentruder app mirrors the display on the machine so you can easily step back from the machine and still get all the information. Update the firmware easily with bluetooth directly from your phone to the MDU3. (Not required to run the machine, but can be helpful for the operator).
Proven, durable slip clutch for main motor
Electronical slip detection for best durability and long lifetime.
Built in display
Display showing angle of the spindle for easy and precise positioning of the rig. Display also shows Amp, voltage, power, RPM, drill depth and much more.
Integrated drive and control electronics
No separate power pack, connect directly to 380 - 480V 50/60HZ 3-phase supply.
