Step drills
The flutes of ZONO high performance step drillsare CBN ground from the solid hardened form. 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 tolerances. This tough tool is suitable for all standard
industrial materials. This durable and versatile tool will
center, spot drill, bore and debur-all in one smooth, high
performance working cycle. By using ZONO cutting spray
or ZONO cutting paste tool life will be considerably prolonged.

3. FluteEach step is axially CBN relief ground. This means the cutting edge is always the highest point of the axial cutting axis.
4. CBN ground relief angleThe cutting edge of each step has relief angle. This means the cutting edge is also the highest point in advance direction.
5. CBN ground bit with split point DIN 1412 CThe CBN ground bit ensures centering and spot-drilling even in thin-walled material.
1. CBN ground fluteCBN ground spiral flutes enable very sharp and burr-free cutting edges compared to the ordinary milled flutes. Especially the chip flow is optimized, so even long, non-breaking chips will be removed easily. The optimized chip flow protects the cutting edges and reduces built-up edges and cold weld marks. Due to these special features, cutting performance and tool life are extended significantly.
2. Radially adjusted relief produced by CBN grindingEach step has a radially adjusted relief produced by CBN grinding that relates directly to the diameter of the step. This means the cutting edge is always the highest point of the diameter.
