Sandvik Coromant CoroDrill® 881 Indexable Insert Drill
The CoroDrill® 881 is designed to bring the productivity and economy of indexable drilling to smaller hole diameters where traditional drills often struggle with stability. Engineered as a highly versatile solution, the CoroDrill® 881 excels in demanding applications, non-standard machining setups, and weak stability conditions, delivering consistent accuracy and long tool life.
Equipped with strong, two-cutting-edge inserts and optimized chip flutes, the CoroDrill® 881 provides excellent chip evacuation and low cutting forces. Its robust body design minimizes tool deflection, making it the ideal choice for multi-operation tasks such as standard drilling, step drilling, plunge drilling, and helical interpolation.
Key Features & Benefits
