Sandvik Coromant 5745714 R390 Milling Insert Solid Carbide

Product Description

The SANDVIK COROMANT 5745714 is a solid carbide milling insert in the R390 series, designed for high-performance face and shoulder milling operations. It carries a parallelogram shape with a 90-degree included angle and a positive rake angle of 22 degrees for efficient chip formation. The insert is coated with TiAlN and TiN via a PVD process, using manufacturer grade 2030. With two cutting edges and a right-hand cutting orientation, this insert is suited for production milling on CNC machining centers where consistent tool life and edge integrity are required. It is held in place by a screw-mount system.

This insert is applied in milling operations on steel, stainless steel, superalloys, and titanium, corresponding to material grades P30, M25, and S20. The MM chip breaker geometry supports a maximum depth of cut of 15.70 mm (0.6181 inches), making it appropriate for both roughing and semi-finishing passes in demanding industrial machining environments. The insert size code is 170424 and the ANSI/ISO catalog designation is R390-17 04 24E-MM 2030. It is intended for use by machinists and tooling specialists working on CNC milling equipment.

Compatibility

Designed for use with R390 series milling cutter bodies. ANSI and ISO code R390-17 04 24E-MM 2030. Verify cutter body pocket specifications before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before seating or removing inserts. Use the correct torx or hex key specified for the screw-hold system to avoid over-torquing the clamping screw. Inspect the cutter body pocket for debris or wear before seating the new insert.
