DiaTiger® Diamond Coated drills excel in carbon fiber composite applications, significantly increasing the number holes drilled in aircraft wing-skins compared with PCD tooling. DiaTiger® coated drills also excel in high silicon aluminum alloys and fiberglass reinforced composite applications. This is attributed to DTC’s unique multi-layer coating grown in a CVD process, along with the ability to coat the entire surface area of complex geometry drills.
