Entering the workpiece with an assymetrical drill by default generates an unbalance. Step technology provide a step-by-step entry with lower cutting forces, and therefore enable a higher productivity as well as close hole tolerances.
An insert for every application
Inserts and geometries, available for all materials and applications, provide high productivity and extended tool life.
More than just a drill
With CoroDrill 880, you can do more than just drilling a hole. The tool can also be used for helical interpolation, boring, plunging, and turning.
Wiper geometry for best surface finish or higher feed possibilities
Optimized chip channels for accelerated chip evacuation
Easy identification due to laser marking with drill-, insert- and screw codes on the drill shank
Two or four cutting edges depending on drill diameter
Optimized geometries assure high performance in most materials
Optimized grades assure longer insert tool life
