Iscar 5509053 WNMX452M4MW IC807 Carbide Turning Insert

Product Description

The ISCAR 5509053 is a solid carbide turning insert with ISCAR grade IC807 and a PVD-applied TiAlN coating. It carries the WNMX insert style designation, which indicates a trigon (W) shape with an 80-degree included angle, a neutral relief angle (N), and a mid-tolerance class (M). The insert measures 8.70 mm (0.3425 inches) in length with a 0.5-inch inscribed circle and a 1/32-inch (0.0313 inches) corner radius. The IC807 submicron carbide grade is engineered for wear resistance and thermal stability at elevated cutting speeds. Licensed HVAC and machining tradespeople familiar with ISCAR tooling will recognize the M4M chip breaker geometry as suited for moderate feed and depth-of-cut applications.

This insert is part of the ISCAR Heliturn series and is designed for external and internal turning operations on a broad range of workpiece materials. The primary workpiece material codes listed are H, K, M, P, and S, covering hardened materials, cast iron, stainless steel, steel, and heat-resistant superalloys respectively. Maximum depth of cut is 5.00 mm (0.197 inches). The insert seats via clamp and pin holding methods. It is suited for CNC turning centers and manual lathes where a positive rake geometry is required for clean chip evacuation and reduced cutting forces.

Key Features

• IC807 submicron solid carbide grade with PVD TiAlN coating for thermal and abrasion resistance
• 80-degree trigon insert shape (WNMX style) with positive rake geometry
• M4M chip breaker optimized for moderate feeds and mid-range depths of cut
• Wiper edge geometry for improved surface finish at standard feed rates
• Dual holding method: clamp and pin for secure seating under interrupted or continuous cuts
• Maximum depth of cut of 5.00 mm (0.197 inches)

Compatibility

Designed as an OEM-style replacement turning insert for toolholders and boring bars accepting WNMX-style inserts with a 0.5-inch inscribed circle. Compatible workpiece material codes include H, K, M, P, and S per ISO 13399 classification. Verify toolholder pocket geometry and insert seat dimensions before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before seating or removing the insert. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer — do not substitute fasteners. Inspect the insert pocket for wear or debris before seating a new insert, as a damaged pocket will compromise cutting performance and edge life.
