Sandvik Coromant 7564382 R390 Milling Insert Solid Carbide

Product Description

The SANDVIK COROMANT 7564382 is a solid carbide milling insert designed for the R390 square shoulder milling cutter series. It carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which improves wear resistance and heat management during cut. The insert is parallelogram-shaped, right-hand, single-sided, with a positive rake angle of 17 degrees and two cutting edges. It measures 0.1875 inches thick with an inscribed circle of 0.3780 inches. ANSI and ISO code R390-17 04 08M-PM 4340 identifies this insert precisely. Licensed machinists and CNC tooling technicians select this insert for high-productivity shoulder milling operations on steel and similar materials.

This insert is suited for milling steel, stainless steel, and cast iron in both roughing and semi-finishing applications. The PM chip breaker geometry supports stable chip evacuation across a range of feed rates and depths. Maximum depth of cut reaches 0.6299 inches, making it capable in both shallow and moderately deep shoulder milling passes. The insert is held by screw in compatible R390 series tool bodies. It is appropriate for production environments running CNC machining centers where consistent insert change-out and predictable tool life are required.

Key Features

• CVD multilayer coating: TiCN, Al2O3, TiN for extended wear resistance in steel and cast iron
• Positive rake angle of 17 degrees reduces cutting forces
• PM chip breaker geometry supports controlled chip formation across feed ranges
• Two cutting edges per insert for cost-effective tooling turnover
• Corner radius of 0.0315 inches (0.80 mm) for corner strength and surface finish consistency
• Meets ANSI and ISO standards; ANSI/ISO code R390-17 04 08M-PM 4340

Compatibility

Designed for use in SANDVIK COROMANT R390 series square shoulder milling cutter bodies. Cutter series compatibility is R390. Insert size code 170408 applies. Screw-on holding method required.

Installation Notes

This insert is installed and replaced by qualified CNC tooling technicians or machinists. Power down and lock out the machine spindle completely before indexing or replacing inserts. Use the correct Torx or hex key for the clamping screw to avoid stripping the screw head — do not overtighten. Inspect the insert seat and screw for damage each time an insert is changed.
