Kennametal 6131426 Milling Insert KCPM40 Solid Carbide

Product Description

The KENNAMETAL 6131426 is a solid carbide milling insert in the LNGU series, designed for high-performance metal removal in demanding machining environments. It carries a dual PVD coating of TiAlN and AlCrN under the manufacturer grade KCPM40, which improves heat resistance and tool life when cutting hard and abrasive workpiece materials. The insert measures 31/64 inches in length and 3/16 inches in thickness, with a 0.0469-inch corner radius and a chamfered, honed cutting edge style. A positive rake geometry and GEM chip breaker promote smooth chip evacuation and reduce cutting forces. This insert is sold individually and is intended for use by machining professionals and CNC tooling specialists.

This insert is suited for milling steel, stainless steel, superalloys, and titanium in both roughing and finishing operations. The LNGU433SRGEM geometry is compatible with the Kennametal Mill 4-11 cutter series. With four available cutting edges on a single-sided, right-hand insert, it provides consistent performance across multiple index positions. Typical applications include face milling, shoulder milling, and pocketing operations on CNC machining centers in job shop and production environments.

Key Features

• Dual PVD coating: TiAlN and AlCrN for heat and wear resistance
• Four cutting edges per insert for extended tooling economy
• GEM chip breaker geometry for efficient chip control
• Positive rake angle reduces cutting forces on difficult materials
• Chamfered and honed cutting edge for edge stability
• Screw-held mounting method for secure, repeatable positioning

Compatibility

Compatible with the Kennametal Mill 4-11 cutter series. ANSI code LNGU433SRGEM; ISO code LNGU110412SRGEM. Designed for machining steel, stainless steel, superalloys, and titanium workpieces.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or socket-head driver as specified by the cutter body manufacturer to seat the crew securely without overtightening. Inspect the insert pocket for debris or damage before seating a new insert to ensure proper contact and runout.
