Iscar 5568612 CNMG431-PP IC830 Turning Insert Isoturn

Product Description

The ISCAR 5568612 is a CNMG431-PP indexable turning insert from the Isoturn series, designed for external and internal turning operations on CNC lathes and turning centers. Manufactured from solid carbide and finished with a PVD-applied AlTiN and TiN dual coating, this insert offers wear resistance and thermal stability across a range of workpiece materials. The insert carries an 80-degree diamond shape (shape code C), a positive rake geometry, and a 0.4 mm (0.0157 inch) corner radius. The PP chip breaker geometry controls chip flow during medium turning passes. Licensed machinists and CNC operators install this insert as part of standard toolholder systems.

The 5568612 is suited for turning applications on materials classified under ISO workpiece codes M (stainless steel), P (steel), and S (high-temperature alloys and titanium). The Isoturn series targets general-purpose external turning and profiling. Maximum depth of cut is 4.00 mm (0.157 inches). The IC830 grade is the ISCAR manufacturer grade designation for this insert, reflecting the carbide substrate and coating combination appropriate for those material groups. This insert is sold individually but requires a minimum order quantity of 10 units.

Key Features

• IC830 PVD-coated solid carbide grade with AlTiN and TiN coating for wear resistance
• 80-degree diamond insert shape (CNMG, shape code C) with positive rake for reduced cutting forces
• PP chip breaker geometry for controlled chip evacuation during medium turning
• 0.4 mm (0.0157 inch) corner radius for general turning and light profiling
• Compatible with ISO workpiece material codes M, P, and S
• Maximum depth of cut 4.00 mm (0.157 inches)

Compatibility

Designed for use in CNMG-style toolholders that accept a size 431 insert with N clearance and M tolerance class. Compatible with workpiece material codes M (stainless steel), P (steel), and S (heat-resistant superalloys and titanium) per ISO 13399. Confirm toolholder insert pocket specifications before installation.

Installation Notes

Installation is performed by qualified CNC machinists or tool-room technicians. Ensure the machine spindle is stopped and the turret is de-energized before indexing or replacing inserts. Seat the insert firmly against the pocket locating surfaces and torque the clamping screw according to the toolholder manufacturer's specification. Inspect the insert seat and clamping components for wear or debris before each insert change to maintain cutting accuracy and prevent premature edge failure.
