Kennametal 5697185 VNMG331FF Carbide Turning Insert

Product Description

The KENNAMETAL 5697185 is a VNMG331FF solid carbide turning insert with a KCP10B multilayer CVD coating (TiCN, Al2O3, TiOCN) engineered for finishing operations on steel and cast iron. The 35-degree diamond (rhombic) insert shape and honed cutting edge deliver consistent surface finish control at light to moderate depths of cut. The insert measures 16.61 mm (1.3076 inches) in length with a 3/8-inch inscribed circle, a 3/16-inch thickness, and a 1/64-inch corner radius. Four available cutting edges extend tool life and reduce per-edge cost. Licensed machinists and CNC turning center operators install this insert in KENLOC-style toolholders for external turning, facing, boring, back turning, and back boring applications.

This insert is suited for finishing cuts on steel (ISO P) workpieces where high wear resistance is required, and on aluminum and non-ferrous materials (ISO N) where a balance of wear resistance and toughness is needed. The neutral hand orientation makes it compatible with both right- and left-hand toolholder setups. The FF chip breaker geometry is optimized for finishing passes, controlling chip evacuation at lower feed rates and shallower depths common in finish-turning cycles. The ANSI size code is 331 and the ISO size code is 160404, which allows direct cross-reference when specifying replacement inserts to standard charts.

Key Features

• KCP10B multilayer CVD coating: TiCN base, Al2O3 mid-layer, TiOCN outer layer for thermal and abrasion resistance
• 35-degree diamond (V) insert shape with honed cutting edge for controlled finishing cuts
• FF chip breaker geometry optimized for finishing operations on steel and non-ferrous materials
• Four cutting edges per insert for extended usable tool life
• Neutral hand orientation compatible with right- and left-hand KENLOC toolholders
• Clamp and pin insert holding method for rigid, repeatable seating

Compatibility

The KENNAMETAL 5697185 is an ANSI VNMG331 / ISO VNMG160404 insert designed for use in KENLOC-series toolholders that accept VNMG-style inserts with clamp and pin retention. It is compatible with primary workpiece materials designated ISO P (steel, cast iron) and ISO N (aluminum and non-ferrous). Verify toolholder pocket geometry and insert retention style before installation.

Installation Notes

Insert replacement should be performed by a qualified machinist or toolroom technician with the machine powered down, the spindle locked, and all guarding reinstalled before resuming cuts. Use the correct torque wrench and clamp screw specified by the toolholder manufacturer — do not estimate clamp force by feel. Inspect the toolholder pocket for wear, chips, or debris before seating a new insert, as a contaminated pocket will shift insert position and reduce edge life. Follow the machine tool manufacturer and cutting tool manufacturer recommendations for starting cutting parameters when transitioning to a new insert grade or geometry.
