Feedmax Solid Carbide Drills

The Feedmax-C1 and Feedmax-C2 solid carbide drills from Seco Tools prevent delamination upon entry or exit when working in carbon fiber reinforced polymer (CFRP) materials. The –C1 geometry features sharp optimized double points, while the –C2 geometry is specifically designed to drill stacked CFRP materials with aluminum or titanium outer layers.

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

Further advancements have also been made with the addition of solid PCD dome tip technology that makes it possible to grind geometries, such as the -C1 and -C2, into a solid PCD tip that is brazed onto a solid carbide drill. The edge sharpness that can be achieved with solid PCD further reduces delamination, uncut fibers, and improves performance.
