Iscar 5507854 WNMG432PP IC8350 Turning Insert Isoturn

Product Description

The ISCAR 5507854 is a WNMG432PP IC8350 grade solid carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. It features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance, thermal barrier performance, and oxidation protection across a range of cutting conditions. The insert has an 80-degree trigon shape (W), a 0.5-inch inscribed circle, and a 1/32-inch corner radius. Insert length is 8.70 mm (0.3425 inches) and insert thickness is 3/16 inch (0.1874 inches). It is held by clamp and pin and carries a Clearance Code N with Tolerance Code M. This insert is used by machinists and CNC operators in production turning operations.

The ISCAR 5507854 is part of the Isoturn series and is engineered primarily for turning stainless steel and carbon or alloy steel workpieces. The PP chip breaker geometry is suited for positive rake cutting, helping to manage chip flow and reduce cutting forces on medium-duty passes. Maximum depth of cut is 4.00 mm (0.1575 inches). This insert fits applications where consistent surface finish and edge life on ferrous materials are priorities, including shaft turning, facing, and contour operations in job shop and production environments.

Compatibility

Designed as an OEM-style replacement or direct-fit insert for turning toolholders that accept WNMG432 style inserts using clamp and pin clamping. Primary workpiece materials are stainless steel (ISO material code M) and steel (ISO material code P).

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine before seating or replacing inserts. Use the appropriate torx or hex key to the toolholder manufacturer's specified clamping method — do not overtighten the clamp screw. Inspect the insert pocket for chips or debris before seating the new insert to ensure proper contact and prevent premature edge failure.
