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.
Diameter 12-84 mm (0.500-3.307 inch)
