In addition to various PCD drills, LEUCO also relies on the special high-performance drill made of solid carbide. The unique and patented point-geometry is the reason for a perfect cutting quality without push-out or peel-up-delamination. Moreover the special geometry extremely reduces the cutting forces while drilling what is the reason for a much longer tool life than known from other typical solid-carbide drills in the composite industry!
In the slow-motion you can see that the drill stabilizes itself. The outer, very sharp cutting edges produce an excellent entry quality because of a “scratching-effect”. The same effect also helps on the exit side.
