Iscar 5504873 Turning Insert Ccmt IC907 Tialn

Product Description

The ISCAR 5504873 is a solid carbide turning insert from the Isoturn series, designed for use in CNC and manual lathe operations. It features an 80-degree diamond shape (insert style CCMT) with a positive rake geometry and a 7-degree relief angle. The insert carries a TiAlN and TiN dual coating applied via PVD process, targeting wear resistance and heat management at the cutting edge. With a 0.25 inch (1/4 inch) inscribed circle and a 1/64 inch corner radius, this insert suits light-to-moderate turning passes. Licensed machinists and CNC operators working in production or job-shop environments are the primary installers.

This insert is suited for turning operations on a range of primary workpiece materials including steel (P), stainless steel (M), cast iron (K), non-ferrous materials (N), high-temperature alloys (S), and hardened materials (H). The SM chip breaker geometry is optimized for controlled chip formation across these material groups. The insert fits standard CCMT-style toolholders and is appropriate for both roughing and finishing passes within its stated depth-of-cut range. It conforms to ISO 13399 standards and carries material grades C7 and C8.

Key Features

• 80-degree diamond insert shape with positive rake for reduced cutting forces
• TiAlN and TiN PVD dual coating for extended tool life in demanding materials
• SM chip breaker geometry for controlled chip evacuation across multiple workpiece materials
• CCMT insert style with screw holding method for secure, repeatable seating
• Maximum depth of cut of 0.0984 inches (2.50 mm) for precision turning applications
• Conforms to ISO 13399 standards

Compatibility

Designed for use in CCMT-style turning toolholders. Compatible with workpiece material ISO codes H, K, M, N, P, and S as designated in the product specifications. Fits toolholders accepting a 0.25 inch inscribed circle CCMT insert.

Installation Notes

Installation is performed by a machinist or CNC operator on a lathe or turning center. Power down and lock out the machine before seating or replacing inserts. The insert is held by a screw clamp; use the appropriate torx or hex key for the toolholder manufacturer's specified fastener. Handle carbide inserts with care to avoid chipping the cutting edge prior to use.
