Sandvik Coromant 7564466 Ball Nose Milling Insert R216

Product Description

The SANDVIK COROMANT 7564466 is a solid carbide ball nose milling insert designed for use in R216 series indexable end mills. Carrying the manufacturer grade designation 4340, this insert features a triple-layer CVD coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability across demanding cutting applications. The insert measures 0.25 inches (6.35 mm) thick and 1.126 inches (17.90 mm) in length, with a convex radius of 0.6299 inches. It is a single-sided, right-hand, positive-rake design with two cutting edges and a screw-type holding method. Installation and use are performed by machinists and CNC operators working in metal-cutting environments.

This insert is suited for milling steel, stainless steel, and cast iron workpieces, corresponding to ISO material grades P40, M40, and K40. The ball nose geometry and M chip breaker designation make it appropriate for profiling, contouring, and finish milling operations at moderate to high depths of cut. The maximum depth of cut reaches 1.126 inches. It is built to ANSI and ISO standards and carries the catalog number R216-32 06 M-M 4340, which applies to both ANSI and ISO identification systems. Typical applications include mold and die work, part profiling, and general-purpose 3-axis and 5-axis CNC machining where controlled chip evacuation and surface finish are priorities.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Power down and lock out the machine spindle before removing or seating inserts. Use the appropriate Torx or hex key for the insert clamping screw and follow the toolholder manufacturer torque sequence. Inspect the pocket seat for chips or debris before seating the new insert to ensure proper contact and runout accuracy.
