Robust design – high impact energy

Secoroc pusher leg and stoper rock drills cover all construction, tunneling and mining applications in different rock formations. They are robust designed, with high impact energy and low air consumption.

The rock drills all have water flushing, rifle bar rotation and the pusher leg control is placed at the back head of the rock drill. An in-line lubricator is included in the delivery of each rock drill.

Together with the appropriate pusher leg, the rock drill forms an attractive and cost effective drilling unit.

Underground rock drills

While efficient and with low energy consumption, the YT27 is durable, reliable and suitable for all applications and all kinds of rock The YT28 rock drill has strong adaptability to the working conditions.The product is energy efficiency, its components has long working life and durability
The YT29A rock drill is the most rugged, powerful and highly efficient rock drill in the range. It gives improved productivity and drill steel economy and can be used on all rock formation and in all kinds of applications. The D-version of the 7655 is a robust and reliable rock drill. It requires less working air pressure and has lower air consumption than the 7655. This makes it suitable for work-sites with low air line pressure or low compressor capacity
The 7655 rock drill is an economical, reliable and durable all-round rock drill which suits most drilling applications.
