Iscar 5507587 Turning Insert SPU422 IC9054 Carbide

Product Description

The ISCAR 5507587 is a solid carbide turning insert in the SPU422 style, manufactured to grade IC9054 and designed for use on CNC lathes and turning centers in metal-cutting operations. The insert carries a multi-layer CVD coating of TiCN, Al2O3, and TiN, which provides wear resistance, heat resistance, and lubricity across the cutting face. It features a square shape with a 90-degree included angle, a 0.5-inch inscribed circle, a 1/8-inch thickness, and an 11-degree relief angle. This combination suits it for general-purpose and finishing turning passes on steel and similar workpiece materials. Installation and tool setup are performed by machinists and CNC operators.

The SPU422 IC9054 insert is intended for external turning and profiling operations on CNC lathes and manual turning machines. The 90-degree square geometry and 1/32-inch corner radius make it suitable for applications requiring a defined shoulder and moderate surface finish. It seats in compatible SPU-style toolholders that accept a square insert with a clamp-style holding method. This insert is typically selected for medium to high-speed turning of steel where CVD-coated carbide grades are specified.

Key Features

• IC9054 carbide grade with multi-layer CVD coating: TiCN, Al2O3, and TiN for extended tool life
• Square insert shape with 90-degree included angle and SPU422 style designation
• 0.5-inch inscribed circle and 1/8-inch insert thickness for consistent seating in compatible toolholders
• 1/32-inch (0.0312-inch) corner radius for general turning and moderate finishing passes
• 11-degree relief angle (clearance code P) with tolerance code U
• Clamp-style insert holding method for positive location in the pocket

Compatibility

Designed as an OEM-style replacement turning insert for SPU-style toolholders that accept a square carbide insert with a clamp holding method and a 0.5-inch inscribed circle.

Installation Notes

Insert changes should be performed with the machine fully stopped and all axes at rest. Use the appropriate torque wrench and clamp hardware specified for the toolholder to secure the insert; do not overtighten or substitute non-OEM clamping hardware. Inspect the toolholder pocket for debris, chips, or wear before seating the new insert. Always verify insert orientation and clearance angle against the toolholder documentation before resuming cutting operations.
