SPMG 050204-DG OS5835 Carbide Drill Insert

The SPMG 050204-DG OS5835 is a high-performance carbide drill insert designed for precision drilling applications on CNC machining centers and conventional machines. With its square geometry (S-shape) and optimized cutting edge, it ensures high hole quality, dimensional accuracy, and stable chip evacuation. The 0.4 mm corner radius makes it particularly effective in fine drilling and semi-finishing operations where surface finish and tool life are critical.

Made in OS5835 grade, the insert uses a fine-grained carbide substrate with a copper-colored PVD coating. This combination provides versatility and durability, making the insert suitable for steels, stainless steels, and cast irons. The DG chipbreaker is engineered specifically for drilling, ensuring smooth chip control, reduced cutting forces, and reliable hole finishing even under demanding conditions.

The SPMG 050204-DG OS5835 fits a wide range of indexable drill bodies designed for SPMG inserts. It is widely used in automotive, aerospace, and precision engineering industries where repeatability, accuracy, and tool life are essential in high-volume drilling applications.
