Kennametal 1611335 WNMG332FN KT315 Cermet Turning Insert

Product Description

The KENNAMETAL 1611335 is a WNMG332FN cermet turning insert in the KT315 grade, designed for high-wear-resistance finishing operations on steel, stainless steel, and cast iron. It features an 80-degree trigon (W) shape with a negative rake angle, a 0.0313-inch corner radius, and a PVD-applied multilayer TiN/TiCN/TiN coating. The insert carries a neutral hand designation and six usable cutting edges, making it a cost-effective option for production turning. It is held by clamp or pin methods and is manufactured to ANSI and ISO dimensional standards. Licensed machinists and CNC turning technicians are the primary installers of this insert.

This insert is suited for finishing passes in CNC turning, facing, and boring operations. Its FN chip breaker geometry is optimized for tight chip control at light depths of cut, with a maximum depth of cut of 0.0492 inches (1.25 mm). It performs across steel (P), stainless steel (M), and cast iron (K) workpiece materials where high surface finish and dimensional accuracy are required. The insert fits KENLOC-series toolholders designed for WNMG-style inserts. It conforms to ANSI insert code WNMG332 and ISO insert code WNMG060408.

• Six cutting edges per insert for extended tool life and reduced tooling cost per edge
• Negative rake, 0-degree relief angle with M-tolerance dimensional accuracy
• Compatible with clamp and pin insert-holding methods
• Conforms to ANSI WNMG332 and ISO WNMG060408 standards

Compatibility

Designed for use in KENLOC-series toolholders accepting WNMG-style inserts conforming to ANSI code WNMG332 and ISO code WNMG060408 with a 0.1500-inch hole diameter.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Before seating the insert, ensure the toolholder pocket and clamping components are clean and free of debris to maintain correct seating and dimensional accuracy. Torque the clamp or pin per the toolholder manufacturer's specifications. Inspect the cutting edge and chip breaker for damage before each use; do not use a visibly chipped or fractured insert.
