Kennametal 6178107 XNGJ0905ANSNGD3W KCSM40 Milling Insert

Product Description

The KENNAMETAL 6178107 is a solid carbide trigon milling insert carrying the XNGJ0905ANSNGD3W ISO designation and KCSM40 manufacturer grade. It is a double-sided, neutral-hand insert with a wiper cutting edge style and GD chip breaker geometry. The PVD-applied TiAlN plus TiN dual coating provides thermal resistance and edge wear protection during high-demand milling operations. With 6 cutting edges and a positive rake geometry, this insert is suited to productive face and shoulder milling cycles on difficult-to-machine alloys. Machinists and CNC tooling specialists working in job shops and production environments select this insert for its combination of edge life and surface finish capability.

This insert is designed for milling steel, stainless steel, superalloys, and titanium alloys, covering ISO material groups P, M, and S. It is compatible with the Kennametal Dodeka cutter series and is held in place by a screw-type insert clamping method. Typical applications include face milling, shoulder milling, and finishing passes where the wiper geometry improves surface finish without requiring a feed rate reduction. The insert meets both ANSI and ISO dimensional standards, with the ANSI code XNGJ535ANSNGD3W and ISO code XNGJ0905ANSNGD3W identifying the geometry precisely for cutter body selection and replacement ordering.

Key Features

• Solid carbide substrate with PVD TiAlN plus TiN dual coating for extended tool life in steel and superalloy milling
• Double-sided insert with 6 cutting edges for reduced cost per edge
• Wiper cutting edge style improves surface finish at standard milling feeds
• GD chip breaker geometry supports positive rake cutting action and chip control in P, M, and S material groups
• Compatible with Kennametal Dodeka cutter series via screw-type insert holding
• Meets ANSI and ISO dimensional standards for drop-in replacement sourcing

Compatibility

Designed for use with the Kennametal Dodeka cutter series. Insert conforms to ANSI code XNGJ535ANSNGD3W and ISO code XNGJ0905ANSNGD3W. Screw-type insert holding method applies. Verified compatible cutter bodies should be confirmed against Kennametal Dodeka tooling documentation before installation.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Use the correct Torx or hex key specified by the cutter body manufacturer to seat the clamping screw — do not overtighten by feel alone; follow the cutter body documentation for fastener procedure. Inspect the pocket seating surface for chips or wear before seating a new insert, as pocket damage directly affects runout and surface finish.
