Sandvik Coromant 7564338 Milling Insert 4330 Carbide

Product Description

The SANDVIK COROMANT 7564338 is a solid carbide milling insert in the 490 series, designed for positive-rake face milling and shoulder milling operations. It carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN under manufacturer grade 4330, targeting steel and cast iron workpiece materials at P30, M30, and K30 material grades. The insert measures 8.50 mm inscribed circle with a 3.30 mm thickness and a 0.80 mm corner radius, delivering four cutting edges per insert. It uses a screw-lock holding method and is suited for use in 490-series cutter bodies.

This insert is intended for professional machining environments where steel and cast iron are the primary workpiece materials. The PM chip breaker geometry is optimized for medium to roughing cuts in those materials, and the right-hand, positive-rake design reduces cutting forces in typical milling passes. The ANSI and ISO code for this insert is 490R-08T308M-PM 4330, and it is compatible with 490-series cutter bodies. Machinists and toolroom professionals working in job shops, production machining, or maintenance repair operations are the typical end users.

Key Features

• CVD-applied TiCN, Al2O3, TiN multilayer coating for extended tool life in steel and cast iron
• Manufacturer grade 4330 rated for P30, M30, and K30 material groups
• Four cutting edges per insert maximizes cost-per-edge value
• Positive rake angle of 26 degrees reduces cutting forces and heat generation
• PM chip breaker geometry suited for medium to roughing depth-of-cut applications
• Maximum depth of cut of 0.2165 inches supports substantial material removal per pass

Compatibility

Designed for use with 490-series cutter bodies. ANSI and ISO designation 490R-08T308M-PM 4330 with insert size code 08T308. Confirmed primary workpiece materials are steel and cast iron (material codes P and K).

Installation Notes

Installation is performed by qualified machinists or toolroom technicians using the screw-lock holding method standard to 490-series cutter bodies. Power down and lock out the machine spindle before seating or removing inserts. Inspect the insert pocket and seating surfaces for debris or damage before installing a new insert. Follow the cutter body manufacturer torque guidance for the insert clamping screw, as overtightening can crack the carbide substrate.
