Sandvik Coromant has introduced a range of drills used 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. These new CoroDrill geometries reduce this risk, ensuring the stringent hole tolerances are met with exceptional finish and quality. The range includes reamer geometries and a countersink tool with microstop for chamfering. Go online to [www.sandvik.coromant.com/us].
