Iscar 5506230 WNMG330NF IC907 Turning Insert Isoturn

Product Description

The ISCAR 5506230 is a WNMG330NF IC907 solid carbide turning insert in the Isoturn series, designed for precision external and internal turning operations on CNC lathes and turning centers. The insert carries a PVD-applied TiN and TiAlN multilayer coating over a submicron carbide substrate, which provides wear resistance and thermal stability across a range of workpiece materials. Key geometry specs include a 3/8 inch (0.3750 inch) inscribed circle, a 0.008 inch corner radius, 80-degree trigon shape, and a positive rake NF chip breaker. The insert seats using clamp or pin holding methods and is installed by machinists and CNC operators in production turning and boring applications.

The WNMG330NF IC907 insert is suited for turning operations on a broad range of materials, including steel, stainless steel, cast iron, nonferrous alloys, heat-resistant superalloys, and hardened materials, as indicated by primary workpiece material codes P, M, K, N, S, and H. The NF chip breaker geometry is optimized for finishing cuts. The Isoturn series is a general-purpose turning line. Maximum depth of cut is 3.00 mm (0.118 inch), making this insert appropriate for light to medium finishing passes. The insert is also rated for boring applications, making it a multi-use tool suitable for both OD turning and ID boring work.

Key Features

• PVD-coated TiN and TiAlN multilayer finish on a submicron solid carbide substrate for extended tool life
• 80-degree trigon (W) insert shape with positive rake geometry for reduced cutting forces
• NF chip breaker designed for finishing operations with controlled chip evacuation
• 0.008 inch corner radius delivers fine surface finish on finishing passes
• Clamp or pin holding method provides secure seating in standard WNMG toolholders
• Multi-use rated for both external turning and boring applications
• Conforms to ISO 13399 tooling data standards

Compatibility

Designed to seat in standard WNMG-style toolholders that accept a 3/8 inch inscribed circle, 80-degree trigon insert with clamp or pin retention. Compatible with toolholders conforming to ISO 13399 WNMG 330 geometry specifications. Suitable for workpiece material codes H, K, M, N, P, and S as designated by the manufacturer.

Installation Notes

Installation is performed by machinists or CNC tooling specialists. Before changing inserts, ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state. Seat the insert fully against the pocket locating surfaces before tightening the clamp or pin; an improperly seated insert can fracture under cutting load. Inspect the toolholder pocket for wear or carbide buildup before installing a new insert.
