Underground drilling with precision and efficiency<\/h2>\n

With a modern and versatile fleet of machines - several of which are customised in our workshop in Norsj\u00f6 - we carry out drilling in varying environments and rock conditions.<\/p>\n

We are fully equipped for drilling in dimensions BQ, NQ2, NQ3, HQ and HQ3. (see table further down the page)<\/em>.<\/p>\n

Our computerised rigs are available in both fully and semi-automatic variants, ensuring a safe working environment, high precision and efficient production.<\/p>\n

To meet the specific needs of our customers, we also offer a wide range of additional services, such as deviation measurement, core orientation, guided drilling and water loss measurement.<\/p>\n

With extensive experience and advanced technology, we deliver accurate and reliable core samples, while minimising environmental impact through innovative solutions and sustainable practices.<\/p>\n

Contact us today to discuss how we can contribute to your project with our expertise in underground drilling!<\/p>\n
