Sandvik Coromant 7564554 Milling Insert Solid Carbide

Product Description

The SANDVIK COROMANT 7564554 is a solid carbide milling insert designed for indexable milling operations on steel, stainless steel, and cast iron. Grade 4340 with a CVD-applied TiCN, Al2O3, and TiN multilayer coating, this insert delivers wear resistance and thermal stability across a range of cutting conditions. The insert measures 9.50 mm wide and 4.45 mm thick, with a 0.80 mm corner radius and four usable cutting edges on a single-sided rectangular body. The positive rake geometry and rounded corner style help manage cutting forces in demanding applications. ANSI and ISO standards compliance is confirmed.

This insert is suited for milling operations in industrial and production machining environments. Primary workpiece materials are steel (P-class), stainless steel (M-class), and cast iron (K-class), covering a broad range of general and specialty machining work. The insert fits the N331.32 cutter series and is held in place by a screw clamp. The ANSI/ISO code is N331.1A-05 45 08H-PL4340, which can be used to cross-reference compatible toolholders and confirm fitment. The PL chip breaker geometry is optimized for these material grades in finish to medium roughing cuts. Maximum depth of cut is 0.2244 inches.

Key Features

• Solid carbide construction with CVD multilayer TiCN, Al2O3, and TiN coating for extended tool life
• Four cutting edges per insert maximizes value per unit
• Positive rake, corner-rounded cutting edge style reduces cutting forces on the workpiece
• Material grades P40, M40, and K40 cover steel, stainless steel, and cast iron applications
• Neutral hand orientation for flexible toolholder compatibility
• Screw-held insert style ensures secure, repeatable indexing

Compatibility

Designed for use with the N331.32 cutter series. ANSI and ISO code N331.1A-05 45 08H-PL4340 should be used to verify fitment with specific toolholders. Insert size code is 054508.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and all energy is locked out before indexing or replacing inserts. Use the correct torx or hex key specified by the toolholder manufacturer when tightening the clamping screw - do not overtighten. Inspect the insert seat and clamp pocket for debris or damage before seating a new insert.
