Iscar 5606673 Milling Insert S845 Snmu 1305ANR-MM IC5400

Product Description

The ISCAR 5606673 is a solid carbide milling insert carrying the ANSI designation S845 SNMU 1305ANR-MM IC5400, designed for use in shoulder and face milling applications on steel and stainless steel workpieces. It features a square insert shape with a neutral hand orientation, a negative rake angle of 24 degrees, and a helical cutting edge style that distributes cutting forces evenly across the edge. The IC5400 grade uses a multi-layer MTCVD coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability during continuous and interrupted cuts. With 8 usable cutting edges on a double-sided body, this insert delivers consistent performance across a full tool life cycle.

This insert is intended for use in CNC milling operations on steel and stainless steel, corresponding to ISO material codes P and M. It is compatible with ISCAR HELIDO series cutter bodies, specifically the SOE45 and SOF45 cutter series. The MM chip breaker geometry is suited for medium machining conditions. Typical installation is performed by machining professionals and tooling setup technicians in precision manufacturing, job shop, and production environments. The insert mounts via screw-lock clamping in the pocket of the compatible cutter body.

Key Features

• Double-sided square insert with 8 cutting edges for maximum index value per insert
• IC5400 grade with MTCVD TiCN, Al2O3, and TiN coating for heat and wear resistance in steel and stainless steel
• Helical cutting edge style with negative 24-degree rake for smooth chip formation and reduced cutting forces
• MM chip breaker geometry suited for medium milling conditions
• 0.80 mm (0.0315 inch) corner radius for controlled edge strength at the insert corner
• Maximum depth of cut of 6.00 mm (0.2360 inches) per pass
• Screw-lock insert holding method for secure seating in compatible HELIDO cutter pockets

Compatibility

Compatible with ISCAR HELIDO series cutter bodies SOE45 and SOF45. Conforms to ANSI code S845 SNMU 1305ANR-MM IC5400 and ISO 13399 standards.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Before indexing or replacing inserts, the spindle must be fully stopped and the machine locked out per applicable shop safety procedures. Seat the insert fully into the pocket and tighten the clamping screw using the appropriate Torx or hex key to the cutter body manufacturer's specified procedure. Inspect the pocket seating surface for chips or debris before installing a new insert to prevent improper seating and premature edge failure.
