The GRUNDODRILL 20N 4.5 is a highly efficient jet drilling rig for complex requirements such as in distribution network construction. With a thrust/pull force of 200 kN and a continuously adjustable torque of 10,000 Nm, the 20N can be optimally adapted to the conditions on site.

The entire concept of the 20N is geared towards performing efficiently and offering the operator maximum ergonomics and ease of use in all tasks. This is achieved by various serial assistance systems such as bore automatics, digital tools such as the BORE DATA app for automatic drilling data log and, last but not least, the well-equipped rotary comfort cabin with touchscreen PC, internet connection and plenty of storage space.

The 4.5 model is equipped with 60 jet drill rods, each 4.5 m long, to carry out even long bores quickly in one piece. The fully automatic rod system ensures high productivity with low idle times and reduces the workload for the operator. The same applies to the crane for the safe handling of rods and accessories. The advantages of the reduced number of rod connections also come into play in cable-guided drilling, for which the GRUNDODRILL 20N can be converted.
