The LRS 275, previously known as the MRS XL MAX is the larger version of our CRS machine. This larger sonic drill accommodates the powerful 50K LargeRotoSonic drill head. Thanks to its larger drilling capacity and higher drilling speed, this sonic drill can handle anything. Even harder surfaces pose no challenge to the LRS 275 thanks to the powerful 50K drill head. The drill head vibrates and rotates at the same time, making it the perfect tool to optimise penetration speed. The drill head has an adjustable true frequency of 150 Hz and comes standard with the automatic drill rod manipulator that allows easy handling of drill pipes without touching them by hand.

The LRS 275 is a robust and powerful drilling rig suitable for a wide range of purposes. The drill rig can be used for mineral sampling, environmental research, geotechnical sampling and testing, geoconstructive drilling and seismic drilling. In addition to being available with a sonic drill head, the machine is also available in DUO version that allows sonic sampling and diamond drilling in the same borehole. The LRS 275 is available in two variants, namely a Pro and a Royal. For detailed specifications, download the overview. Is one of our standard models not exactly what you are looking for?
