Kennametal 6441068 Milling Insert KCSM40 Solid Carbide

Product Description

The KENNAMETAL 6441068 is a solid carbide milling insert in the XDLT series, designed for high-performance face and shoulder milling applications. Manufactured to ANSI and ISO standards under catalog number XDLT120512ERD411, this square-shaped insert features a TiAlN and TiN dual coating applied via PVD process. It carries a positive rake geometry, a 15-degree relief angle, and a honed cutting edge style. With four cutting edges per insert and a corner radius of 0.047 inches (1.19 mm), it delivers consistent, repeatable performance in production milling environments. Licensed HVAC and mechanical trades should note this is a cutting tool insert intended for CNC and manual milling machine spindle tooling.

This insert is suited for milling steel, stainless steel, superalloys, and titanium workpieces, corresponding to ISO material groups P, M, and S. It is designed for use in right-hand cutter bodies and is compatible with the Kennametal 7792VXD12 cutter series. The D411 chip breaker geometry helps manage chip evacuation in demanding cuts, making this insert appropriate for aerospace, energy, and general metalworking applications where difficult-to-machine materials are common. Inserts are sold individually with a minimum order quantity of 5 units.

Key Features

• Solid carbide substrate with TiAlN and TiN PVD coating for wear resistance in steel and superalloy milling
• Square XDLT insert shape with 90-degree included angle and positive rake for reduced cutting forces
• Four usable cutting edges per insert maximizes tooling value
• Honed cutting edge style reduces micro-chipping in difficult workpiece materials
• D411 chip breaker geometry supports chip control at moderate-to-aggressive depths of cut up to 0.326 inches
• Right-hand orientation; screw-held mounting for secure clamping in compatible cutter bodies

Compatibility

Designed for use in the Kennametal 7792VXD12 cutter series. Cutter series compatibility code is XDLT; ANSI and ISO code XDLT120512ERD411. Verify cutter body pocket geometry and insert size code 120512 before installation.

Installation Notes

Installation is performed by a machinist or toolroom technician. Always power down and lock out the machine spindle before seating or replacing inserts. Use the manufacturer-specified torx or hex key to tighten the clamping screw; do not use impact drivers. Inspect the cutter pocket seating surface for wear or debris before installing a new insert to ensure proper support and runout.
