Sandvik Coromant CoroDrill® 880 has unrivalled holes


challenge:
Achieve safe and predictable drilling.
solution:
Equipped with indexable drill bits for complete specifications and blades for a wide range of machining conditions.
The CoroDrill® 880 - indexable insert drill with GC4324 and GC4334 inserts is capable of machining holes with tolerances in the IT12 - IT13 range and is suitable for machining holes up to 5 times the drill diameter. Stepping technology ensures excellent cutting force balance, which significantly increases productivity and hole quality. Combined with high-performance inserts and geometries, the drill is the first choice for safe hole machining at high productivity.
The CoroDrill 880 is now equipped with a safer and more predictable blade material that significantly extends tool life.

GC4324 and GC4334 are extremely wear resistant materials for indexable inserts. InveioTM is the secret behind these two blade material technologies, which ensure that tightly wrapped unidirectional crystals form a solid barrier towards the cutting area and chip direction. Combined with the fine-grained TiCN technology, these two materials not only have a hard wear-resistant coating that is resistant to abrasive wear, but also improve the resistance to crater wear and flank wear. The heat generated during drilling is quickly directed away from the cutting area, extending the life of the cutting edge. GC4324 and GC4334 are suitable for drilling all types of carbon steel, stainless steel, cast iron and hardened materials.
