Sandvik offers a range of drills designed for rivet and bolt holes in carbon reinforced plastics and metallic stack materials. Each carbon fiber material has its own demands, which increases the risk for delamination or splintering.

The range includes reamer geometries and a countersink tool with microstop for chamfering.
