Iscar 5505912 Turning Insert Cpmt 2-2-PF IC907 Carbide

Product Description

The ISCAR 5505912 is a solid carbide turning insert in the CPMT 2-2-PF IC907 geometry, part of the Isoturn series. It features an 80-degree diamond insert shape with a positive rake angle and a PF chip breaker for controlled chip formation during turning operations. The insert is PVD-coated with TiAlN and TiN layers under the IC907 manufacturer grade, targeting a broad range of workpiece materials. With a 0.25-inch inscribed circle, a 0.0315-inch corner radius, and a maximum depth of cut of 2.50 mm (0.0984 inches), this insert is sized for light to medium turning passes. Licensed machinists and CNC lathe operators install this insert on compatible toolholders using a screw-clamp holding method.

This insert is rated for universal primary workpiece material application, covering ISO material groups H, K, M, N, P, and S. That range includes steel, stainless steel, cast iron, non-ferrous metals, heat-resistant superalloys, and hardened materials. It is suited for external and internal turning operations on CNC lathes and turning centers in both production and job-shop environments where a single insert geometry must cover multiple material types without frequent grade changes.

Key Features

• IC907 grade with PVD-applied TiAlN and TiN dual-layer coating for extended tool life across universal materials
• 80-degree diamond insert shape (Shape Code C) with positive rake for reduced cutting forces
• PF chip breaker geometry for reliable chip control in light to medium cuts
• Screw-clamp insert holding method for secure, repeatable seating in compatible toolholders
• Maximum depth of cut: 2.50 mm (0.0984 inches)
• Compliant with ISO 13399 tooling data standards for digital tooling integration

Compatibility

Designed as an OEM-style replacement or direct application insert for CPMT-style screw-clamp turning toolholders accepting a 0.25-inch inscribed circle, 80-degree diamond insert in the Isoturn series geometry.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine before indexing or replacing inserts. Use the correct torx or hex key to seat the clamping screw to the toolholder manufacturer's specified method without over-torquing the screw. Inspect the insert pocket for chips or debris before seating to ensure full insert contact and accurate tool-nose positioning.
