Sandvik Coromant 7564444 Milling Insert R245 4340 Carbide

Product Description

The SANDVIK COROMANT 7564444 is a solid carbide milling insert designed for use in R245 series face milling cutters. Manufactured to grade 4340 with a multi-layer CVD coating of TiCN, Al2O3, and TiN, this insert delivers wear resistance and thermal stability across demanding cutting operations. The square insert geometry features a positive 10-degree rake angle and corner-rounded cutting edge style with a 1.00 mm corner radius. With 4 cutting edges and a maximum depth of cut of 9.75 mm, it is suited for productive material removal in steel, stainless steel, and cast iron applications. Installation is performed by licensed machinists and CNC tooling technicians.

This insert is sized to the 18T6 insert size code with an inscribed circle of 18.00 mm and a thickness of 6.10 mm. It is intended for use in face milling, shoulder milling, and general-purpose milling operations on steel, stainless steel, and cast iron workpieces. The PM chip breaker geometry supports stable chip control across a range of feed rates and depths. The right-hand cutting orientation and screw-in holding method make it compatible with standard R245 cutter bodies requiring 18T6-format inserts.

Key Features

• Solid carbide substrate with CVD-applied TiCN, Al2O3, and TiN multilayer coating for extended tool life
• 4 usable cutting edges per insert for cost efficiency in high-volume milling
• 1.00 mm corner radius with corner-rounded edge style reduces cutting forces and chipping risk
• Positive 10-degree rake angle supports lower cutting forces on steel and stainless steel
• PM chip breaker geometry promotes consistent chip evacuation at moderate to high feed rates
• Meets ANSI and ISO standards; ANSI/ISO code R245-18 T6 M-PM 4340

Compatibility

Designed for use with Sandvik Coromant R245 series cutter bodies requiring 18T6 insert size format. Rated for primary workpiece materials P (steel), M (stainless steel), and K (cast iron) per ISO material classification. Material grades P40, M40, and K40 apply.

Installation Notes

This insert is installed and indexed by machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or hex key for the cutter body screw to seat the insert securely without over-torquing. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert.
