Iscar 5590820 WNMG433TF IC908 Turning Insert Tialn Carbide

Product Description

The ISCAR 5590820 is a solid carbide turning insert in the WNMG433TF geometry, coated with TiAlN via a PVD process under the IC908 manufacturer grade. Designed for external and internal turning operations, this insert features an 80-degree trigon shape with a positive rake angle and a TF chip breaker geometry. The inscribed circle measures 0.5 inches, the corner radius is 3/64 inches (0.0472 inches), and the insert length is 0.3425 inches (8.70 mm). The IC908 grade delivers high wear resistance across a range of workpiece materials. Installation is performed by qualified CNC machinists and toolroom technicians using clamp and pin holding methods.

This insert is suited for turning applications across ferrous and non-ferrous workpiece materials. Primary workpiece material categories include cast iron (K), stainless steel (M), and carbon and alloy steel (P). Secondary categories include hardened materials (H) and heat-resistant superalloys (S). The TF chip breaker geometry supports controlled chip formation at moderate to high feed rates. It is part of the ISCAR Isoturn series and conforms to ISO 13399 standards, making it compatible with standard WNMG toolholders used in CNC turning centers and manual lathes.

Key Features

• IC908 grade with TiAlN PVD coating for wear resistance across multiple material categories
• 80-degree trigon insert shape (W) with positive rake for reduced cutting forces
• TF chip breaker geometry for controlled chip evacuation at moderate to high feeds
• Clamp and pin holding method for secure seating in standard WNMG pockets
• Conforms to ISO 13399 tooling data standards
• Maximum depth of cut up to 0.177 inches

Compatibility

Designed as an OEM-style replacement insert for standard WNMG-style toolholders used in CNC turning centers and manual lathes. Compatible with toolholders accepting a 0.5-inch inscribed circle WNMG insert with clamp and pin retention. Refer to your toolholder documentation to confirm pocket geometry before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine before changing inserts. Seat the insert fully in the pocket and secure using the clamp and pin method before resuming cuts. Do not exceed the recommended depth of cut for the selected toolholder and insert combination.
