Iscar 5502807 Cnmg 432-PP IC28 Turning Insert Solid Carbide

Product Description

The ISCAR 5502807 is a solid carbide uncoated turning insert in the CNMG 432-PP geometry, part of the Isoturn series. It features an 80-degree diamond insert shape with a 0-degree relief angle (clearance code N) and a positive rake for efficient chip evacuation. The inscribed circle measures 0.5 inches, insert length is 0.5079 inches (12.90 mm), and the corner radius is 0.0315 inches (1/32 inch). The PP chip breaker geometry is engineered for controlled chip flow. This insert is installed and replaced by machinists and CNC turning specialists in production and job-shop environments.

The 5502807 is suited for turning operations on non-ferrous materials as its primary workpiece designation (ISO material group N), with secondary compatibility across ISO material groups M (stainless steel), P (steel), and S (heat-resistant superalloys). It fits standard CNMG-style turning toolholders that accept a 0.2030-inch hole diameter. Typical applications include external and facing turning passes where a sharp, positive geometry and tight tolerance (tolerance code M) are required for consistent part finish and dimensional control.

Key Features

• Solid carbide uncoated construction, material grades C5 and C6
• 80-degree diamond insert shape with positive rake for reduced cutting forces
• PP chip breaker designed for controlled chip formation across multiple material groups
• Tolerance code M provides close dimensional consistency insert-to-insert
• Maximum depth of cut: 0.1575 inches (4.00 mm)
• Compatible with clamp and pin insert holding methods
• Conforms to ISO 13399 tooling data standards

Compatibility

Designed for use in CNMG-style turning toolholders with a 0.2030-inch center hole diameter. Compatible with ISO material groups N (primary), and M, P, and S (secondary) per the manufacturer designation. Part of the ISCAR Isoturn series.

Installation Notes

This insert is seated and secured by a machinist or CNC operator in a compatible CNMG toolholder using the clamp and pin holding method. Power down and lock out the spindle before changing inserts. Ensure the insert pocket and seating surfaces are clean and free of chips before seating the new insert to maintain correct geometry and tool life. Follow the toolholder manufacturer torque guidance for clamping screws rather than over-tightening, which can fracture the carbide substrate.
