Iscar 5505570 Turning Insert Tpmt 2-1 IC907 Carbide

Product Description

The ISCAR 5505570 is a solid carbide turning insert designed for precision metal-cutting applications on CNC lathes and turning centers. It carries the TPMT insert style with a triangular shape and a 60-degree included angle, providing three usable cutting edges per insert. The IC907 grade features a PVD-applied TiAlN and TiN dual coating that supports cutting in a wide range of workpiece materials including steels, stainless alloys, and high-temperature superalloys. The insert measures 11 millimeters in length with a 0.25-inch inscribed circle and a 0.0157-inch corner radius. It belongs to the Isoturn series and is installed using a screw-type holding method. This insert is typically specified and installed by CNC machinists and tooling technicians in production or job-shop environments.

This insert is suited for turning operations on materials classified under ISO material groups H, K, M, N, P, and S, covering hardened steels, cast irons, carbon and alloy steels, non-ferrous metals, stainless steels, and heat-resistant superalloys. The maximum depth of cut is 3 millimeters (0.118 inches), making it well-matched for finishing and light semi-finishing passes. It fits into TPMT-compatible toolholders commonly used in both external and internal turning setups. The T chip breaker geometry promotes controlled chip formation across the supported material range.

Key Features

• IC907 grade with PVD TiAlN and TiN dual coating for extended tool life across multiple material groups
• Triangular insert shape with 60-degree included angle and positive rake for lower cutting forces
• 0.0157-inch corner radius suitable for finishing and light semi-finishing operations
• Screw-type insert holding method for repeatable, secure seating in the toolholder
• Maximum depth of cut of 3 millimeters (0.118 inches)
• Conforms to ISO 13399 tooling data standards for compatibility with CAM and tool management systems

Compatibility

Designed for use in TPMT-style screw-clamp toolholders within the Isoturn series. Compatible with workpiece material groups H, K, M, N, P, and S per ISO classification. Refer to ISCAR toolholder documentation to confirm bore and seating geometry before installation.

Installation Notes

This insert is installed and changed by qualified CNC machinists or tooling technicians. Power down and lock out the machine spindle before accessing the toolholder. Use the appropriate Torx or hex key to seat and torque the clamping screw according to the toolholder manufacturer specifications. Inspect the insert pocket and seating surface for chips or debris before installing a new insert to ensure full contact and accurate edge positioning.
