Sandvik Coromant 7564582 Milling Insert Grade 4330 R300

Product Description

The SANDVIK COROMANT 7564582 is a round, single-sided solid carbide milling insert designed for use in R300 series face and shoulder milling cutters. Manufactured to grade 4330, the insert carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, delivering a balance of wear resistance and toughness suited for moderate to heavy milling operations. The inscribed circle measures 12.00 mm (0.4724 inches), thickness is 3.97 mm (0.1563 inches), and the insert provides 6 usable cutting edges. The PH chip breaker geometry and positive rake angle support controlled chip formation across a range of cutting conditions. Licensed machinists and CNC tooling technicians are the primary installers.

This insert is engineered for milling steel and cast iron workpieces, covering ISO material groups P and K, and material grades P30, M30, and K30. It is suited for both roughing and semi-finishing passes in production environments where tool life consistency is a priority. The neutral hand orientation allows flexible application across standard R300 tooling setups. Typical use cases include face milling, profile milling, and shoulder milling operations on machining centers and milling machines running steel components and gray or ductile cast iron parts.

Key Features

• Round insert shape with 360-degree included angle and 6 cutting edges for maximum index count per insert
• CVD multilayer coating: TiCN plus Al2O3 plus TiN for combined crater and flank wear resistance
• Grade 4330 solid carbide substrate targets steel and cast iron applications (P30, M30, K30)
• Positive rake angle with PH chip breaker geometry for controlled chip evacuation
• Maximum depth of cut: 3.00 mm (0.1181 inches)
• Screw-held mounting with neutral hand orientation for standard R300 cutter bodies

Compatibility

Designed for use with Sandvik Coromant R300 series cutter bodies. ANSI and ISO code: R300-1240M-PH 4330. Insert size code 1240 with an inscribed circle range of 0.4000 to 0.5000 inches. Conforms to ANSI and ISO indexable insert standards.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the manufacturer-specified torque wrench and insert screw to secure the insert in the pocket — do not overtighten or substitute non-OEM screws, as this can fracture the carbide body. Inspect the insert pocket seat and clamping screw for wear or damage at each index interval.
