Kennametal 1160214 Turning Insert DNMG431 KC850 Carbide

Product Description

The KENNAMETAL 1160214 is a DNMG431 geometry turning insert in grade KC850, designed for external and internal turning operations on CNC and manual lathes. The insert is manufactured from solid carbide and features a multilayer CVD coating of TiC, TiCN, and TiN, which provides a balance of moderate wear resistance and toughness across a wide range of workpiece materials. The 55-degree diamond (rhombic) shape, negative rake, and negative side clearance suit it to medium machining applications where stable tool holding and predictable edge life are required. Four usable cutting edges deliver cost efficiency per part run.

This insert is suited for turning, facing, boring, back turning, and back boring operations on steel, stainless steel, and cast iron, as well as special and super alloys. It belongs to the KENLOC series and is held by clamp or pin methods. Typical applications include medium-pass finishing and semi-finishing cuts in production turning environments. Licensed machinists and toolroom technicians working with ISO or ANSI toolholders sized for DNMG inserts will find this a direct-fit option. The chip breaker geometry targets medium machining chip loads.

Key Features

• Multilayer CVD coating (TiC, TiCN, TiN) for wear resistance across steel, stainless steel, and cast iron
• 55-degree diamond insert shape (ANSI: DNMG431 / ISO: DNMG150404) with negative rake and negative clearance
• Four cutting edges per insert for extended tooling value
• Compatible with clamp and pin holding methods in KENLOC-style toolholders
• Chamfered and honed cutting edge preparation for edge stability during entry and interrupted passes
• Multi-use geometry supports turning, facing, boring, back turning, and back boring

Compatibility

Designed as an OEM-style replacement or direct fit for DNMG431-geometry toolholders conforming to ANSI and ISO standards. Compatible workpiece materials include steel (P), stainless steel (M), cast iron (K), and special and super alloys (S) per ISO material classification.

Installation Notes

This insert is installed by qualified machinists or toolroom technicians familiar with indexable turning toolholder systems. Power down and de-energize the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench or clamp screw driver as specified by the toolholder manufacturer when seating the clamp or pin. Inspect the insert pocket and seating surface for chips or debris before installation to ensure proper seating and edge alignment.
