PCD Tipped Spiral Drills

A PCD Tipped Twist Drill is a high-end hole-making tool in which polycrystalline diamond (PCD) cutting edges are precisely brazed or sintered onto a carbide body. Its core advantage lies in the exceptional properties of PCD, enabling high-precision and high-volume drilling in demanding materials such as CRP, CFRP, graphite, ceramics, and non-ferrous metals.
