Dormer has expanded its solid carbide replaceable-head drilling program with its Hydra drills that provide high productivity across a range of materials and applications. The units are an alternative to solid carbide drills. Two head types are available. The R950—with diameters up to 42.0 mm—is offered for drilling operations in carbon and alloy steels. The R960 is ideal for stainless steel and cast iron but is also recommended for use in titanium and nickel. Both head types incorporate a self-centering, 140° four-facet split point. This feature ensures low thrust forces throughout the drilling cycle, promoting consistently high performance. The heads can be changed without removing the body from the spindle, thus reducing machine downtime.
