for non-ferrous materialsfor steelfor stainless steel

Each drill body size is individually optimized and has a never-before-seen stiffness to ensure high process security, repeatability, consistent quality and good run-out accuracy. Twisted coolant holes for maintained drill body rigidity and variable chip flutes with optimized shapes for safe chip evacuation. The robust insert seats have three support contact surfaces for less insert movements. The inserts are strong and have a bulk strength that provides extra toughness resulting in unmatched insert tool life. The ground peripheral insert allows for closer hole tolerance, predictability and consistent performance. This 7×DC insert drill with innovative drill body and insert designs makes it possible for cost-effective and reliable drilling of deep holes with less demanding hole tolerances. No pilot drilling needed which saves both time and money.
