Mining and tunneling often starts with a hole. Why, how and where you drill that hole varies substantially,which means you have to have the right products (from the rock drill down to the drillbit) to work effectively and productively, with high availability for a long time. Sandvik makes drills and rock tools for all possible applications such as drifting, production drilling, presplitting, wall control and grade control. This includes rotary, DTH and top hammer drilling methods for surface and underground applications. We make rigs and rock tools that drill for coal, copper, iron, gold, zinc, diamonds, and a large variety of other materials.
