The flutes of BAIKE high performance step 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.

      This tough tool is suitable for all standard industrial materials: nonferrous metal, special steel,thermoplastics and duroplastics as well as sheet metals up to 4,0 mm thickness.

            This durable and versatile tool will center, spot drill, bore and debur - all in one smooth, high performance working cycle.
