TUBE AND SHEET DRILLS
03 Tube and sheet drills The flutes of the RUKO high performance tube and sheet drills are CBN ground from the solid hardened form. Because CBN (cubical boron nitride) is a much harder abrasive than even silicium carbide or corundum, a better and sharper cutting edge is achieved - without burrs. And, with higher dimensional precision the drills will last considerably longer while maintaining the precise process tolerances.
