Sandvik Coromant 5854742 Milling Insert Grade 3220

Product Description

The SANDVIK COROMANT 5854742 is a solid carbide milling insert in the 490 series, engineered for high-productivity face and shoulder milling operations. It carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, corresponding to manufacturer grade 3220 and material grade K15. The square insert geometry features a positive 23-degree rake angle with corner-rounded cutting edges and a 0.80 mm corner radius, delivering smooth entry and reduced cutting forces. With four usable cutting edges per insert, it offers consistent tool life across a broad range of applications in cast iron machining.

This insert is intended for use in cast iron workpiece materials, classified under primary material code K. It is sized to the 490 series cutter platform, identified by ANSI and ISO code 490R-140408M-PM 3220, and uses the PM chip breaker geometry. Typical install scenarios include CNC machining centers and manual milling machines where shoulder milling, face milling, or ramping in cast iron is required. Installation is performed by machinists and tooling specialists working with compatible 490-series milling bodies.

Key Features

• CVD multilayer coating: TiCN, Al2O3, TiN for wear resistance and thermal stability in cast iron
• Four cutting edges per insert for extended tool life and lower cost per edge
• Positive 23-degree rake angle reduces cutting forces and heat generation
• Corner-rounded cutting edge style with 0.80 mm corner radius minimizes chipping
• Maximum depth of cut of 10.00 mm supports aggressive material removal rates
• Single-sided, right-hand insert secured by screw clamp for repeatable seating

Compatibility

Designed for use with SANDVIK COROMANT 490 series milling cutter bodies. ANSI and ISO designation 490R-140408M-PM 3220 confirms fitment within the 490 platform. Verify cutter body pocket dimensions and insert size code 140408 before installation.

Installation Notes

Insert replacement is performed by qualified machinists or tooling technicians. Disengage the machine spindle and lock out the machine before handling inserts. Use the appropriate Torx or hex key driver specified by the cutter body manufacturer to seat the clamping screw to the correct seating torque per the cutter body documentation. Inspect the pocket seating surface for wear or debris before installing a fresh insert to ensure accurate positioning and full cutting-edge engagement.
