Sandvik Coromant 7564472 Ball Nose Milling Insert RA216

Product Description

The SANDVIK COROMANT 7564472 is a solid carbide ball nose milling insert designed for use in indexable end mills and milling cutters. It features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability across a range of metal-cutting applications. The insert measures 0.1875 inches (4.76 mm) thick and 0.8930 inches (22.68 mm) in length, with a convex radius of 0.4921 inches. It carries a right-hand cutting orientation, a positive rake angle of 0 degrees, and a rounded cutting edge style with two cutting edges. Grade 4340 targets steel, stainless steel, and cast iron. Licensed machinists and CNC tooling technicians are the primary installers of this type of insert.

This insert fits within the RA216 cutter series and is sized to the 2504 insert size code. It is suited for ball nose profiling, contouring, and semi-finish milling operations on steel, stainless steel, and cast iron workpieces. The maximum depth of cut reaches 0.8930 inches. The screw-holding method secures the insert in compatible RA216 toolholders. The M chip breaker geometry supports general-purpose cutting across the P40, M40, and K40 material grade classifications as defined under ANSI and ISO standards. ANSI and ISO codes for this insert are both listed as RA216-25 04 M-M 4340.

Installation Notes

This insert is installed and replaced by machining technicians or CNC setup personnel. Power down and lock out the machine spindle before removing or seating any indexable insert. Use the correct Torx or hex key to secure the clamping screw without over-driving, and inspect the insert pocket for chips or debris before seating the new insert. Handle carbide inserts carefully to avoid edge chipping during installation.
