Seco Tools has announced additions to its line of Feedmax solid-carbide drills that avoid delamination upon entry or exit when drilling in carbon fiber reinforced polymer (CFRP) materials. The new -C1 geometry features a sharp optimized double points, while the -C2 geometry is specifically designed to drill stacked CFRP with an aluminum or titanium outer layer.

To combat the abrasive properties of CFRP, the Feedmax -C1 and -C2 incorporate a polycrystalline diamond coating, which also provides good dimensional tolerance. The new drills are 5xD with diameters ranging from 0.1260" to 0.5". All -C1 and -C2 drills feature through-coolant holes.
