• Ubuntu Rock Drilling has the capability to drill all of the following core diameters: ATX (32.51mm), BQ(36.4mm), Q (47.63mm), TNW(60.81mm), HQ(63.81mm), PQ(84.96mm), T6-146(128.8mm) and ZWF(165mm) • BQ, NQ, HQ and PQ are all wire line core drilling where the core is brought to the surface using a wire line cable and winch. This time saving method is normally used for deep holes resulting in more meters drilled per shift • TNW, T6-146 and ZWF are all conventional drilling operations where the rods have to be pulled to bring the core barrel and core to the surface. Although this method is a bit slower than the wire line method it produces a larger diameter core, as sometimes required by the laboratories • Geotechnical drilling where loose or unconsolidated material is drilled to produce an in-situ or undisturbed soil sample. This is accomplished by using specialised core barrels like the NWD4 (54mm) or triple tube core barrel
