Iscar 5504876 Turning Insert Dnmg 432-TF IC907 Carbide

Product Description

The ISCAR 5504876 is a DNMG 432-TF solid carbide turning insert in the Isoturn series, finished with a PVD-applied TiAlN coating and graded IC907. It carries a 55-degree diamond shape with a positive rake geometry and a neutral (N) clearance angle. The inscribed circle measures 0.5 inches, the insert length is 15.5 mm (0.6102 inches), and the corner radius is 1/32 inch (0.0315 inches). The TF chip breaker geometry promotes controlled chip evacuation during finishing and medium turning operations. Licensed machinists and CNC turning-center operators are the primary installers of this insert.

This insert is suited for turning operations on hard-to-machine materials. The IC907 grade and TiAlN PVD coating target primary workpiece material groups H (hardened steels), M (stainless steels), and S (superalloys and titanium), along with K, N, and P material groups. Maximum depth of cut is 3.50 mm (0.138 inches). It is used in both production and job-shop environments on CNC lathes and turning centers requiring consistent surface finish and edge retention over extended tool life. The TF chip breaker style is optimized for finishing passes where tight tolerances and low cutting forces matter.

Key Features

• IC907 grade PVD TiAlN coating for extended wear resistance on hardened, stainless, and superalloy materials
• 55-degree diamond insert shape (DNMG style) provides two usable cutting edges per insert
• TF chip breaker geometry designed for finishing and light-to-medium turning passes
• Positive rake angle reduces cutting forces and heat generation at the cutting edge
• Compatible with both clamp and pin insert-holding methods for flexible toolholder pairing
• Meets ISO 13399 standard for consistent tooling data exchange and setup accuracy

Compatibility

Designed as a direct-fit replacement in ISCAR Isoturn toolholders configured for DNMG 432-style inserts using clamp or pin holding methods. Refer to ISCAR Isoturn toolholder documentation to confirm seat and clamping compatibility before use.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist following the toolholder manufacturer's torque and clamping specifications. Power down and lock out the machine spindle before changing inserts. Inspect the insert pocket for debris or damage before seating the new insert. Do not exceed the rated maximum depth of cut for this insert geometry.
