Sandvik Coromant 7564442 Milling Insert 4340 R245

Product Description

The SANDVIK COROMANT 7564442 is a solid carbide milling insert designed for indexable face and shoulder milling operations in demanding production environments. This single-sided, square-shaped insert carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN in the manufacturer grade 4340, offering wear resistance and heat management across a range of workpiece materials. It fits the R245 cutter series, features a positive rake geometry at 15 degrees, and provides four cutting edges per insert. The insert size code is 12T3, with a maximum depth of cut of 6.50 mm. Machining professionals and tooling specialists install these inserts in CNC machining centers and milling machines as part of a systematic insert management program.

This insert is intended for use with R245-series face milling cutter bodies in industrial and production shop environments. Primary workpiece materials include steel, stainless steel, and cast iron, corresponding to ISO material groups P, M, and K. The material grade designations P40, M40, and K40 indicate suitability for medium to roughing cuts in these material families. The right-hand insert hand designation and corner-rounded cutting edge style with a 1.50 mm corner radius make this insert well suited for general-purpose face milling where surface finish and tool life consistency are priorities. The ANSI and ISO code for this insert is R245-12 T3 M-PM 4340.

Key Features

• CVD multilayer coating: TiCN, Al2O3, TiN for enhanced wear and heat resistance
• Four cutting edges per insert for extended tool life and cost efficiency
• Positive rake angle of 15 degrees reduces cutting forces on the workpiece
• Corner-rounded cutting edge style with 1.50 mm corner radius for controlled surface finish
• Maximum depth of cut of 6.50 mm suitable for medium to roughing face milling passes
• Compatible with PM chip breaker geometry for steel and stainless steel chip control
• Screw-held insert mounting for secure, repeatable seating in the cutter body

Compatibility

Designed for use with R245-series indexable milling cutter bodies as specified by the cutter series compatibility designation. ANSI and ISO code R245-12 T3 M-PM 4340 confirms fit within the R245 platform.

Installation Notes

Installation is performed by machinists or tooling technicians using the appropriate Torx or hex key for the insert clamping screw — consult the cutter body documentation for the correct fastener specification. Always power down and lock out the spindle before indexing or replacing inserts. Inspect the insert pocket seat and clamping screw threads for wear or contamination before seating a new insert. Do not exceed the maximum depth of cut specified for the insert and cutter body combination.
