Sandvik Coromant is releasing three grades for its CoroDrill 870 exchangeable-tip drill.
The three grades, GC4344, GC3334, and GC2334, have been developed to offer tool life improvements and more predictable wear patterns, while maintaining the high penetration rates and productivity.
The grades have been produced with a physical vapour deposition called Zertivo, which is a production technology developed by the company.
The grades cover applications in most ISO materials, although are mainly optimized for steel, stainless steel, and cast iron. All grades are PVD-coated using Zertivo, and are designed to deliver specific enhancements related to common wear issues in drilling.
The Zertivo technologyÂ’s properties consist of edge-line security, chipping resistance, and overall wear resistance.
