CoroDrill® 880

Indexable insert drills

Step technology

​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
