Drilling Systems & Drill Rods

The E6 Hard Materials Dolomite drilling system has reamers fitted with three symmetrically arranged carbide tips. This system is mainly used in medium to hard rock formations. The reamers can be assembled in two positions allowing the tips to be placed at either 10° or 30° from each other, which provides more flexibility in matching the bit to the drilling conditions. The Dolomite system is normally supplied with a female thread. Other thread types are available upon request.

In addition to our Dolomite drilling system, we offer large hole drill heads with round shank picks as well as with cutting teeth. These heads are mainly used for drilling of blasting relief holes in rock formations with medium hardness.

As well our drilling systems, we offer rotary drill rods for roof bolting in lengths of 0.3 - 2.8 m. Available diameters are 19 and 22mm hex and also 20 mm round. Our rotary drill rods are suitable for all common threads.
