Kennametal 5660041 Milling Insert SP6519 Tialn Carbide

Product Description

The KENNAMETAL 5660041 is a solid carbide milling insert carrying manufacturer grade SP6519 and a PVD-applied TiAlN coating. It belongs to the ADKT series and features a parallelogram insert shape with a 15-degree relief angle. At 0.148 inches thick and 0.31 inches inscribed circle diameter, this insert is sized for precise, high-performance milling operations. The TiAlN coating improves heat resistance and tool life when cutting ferrous and difficult-to-machine materials. Installation is performed by licensed machinists and tooling technicians in CNC milling setups where insert geometry and grade selection directly impact surface finish and cycle time.

This insert is intended for milling steel, stainless steel, superalloys, and titanium alloys. The ADKT series geometry with a chip breaker designation of 45 makes it well suited for roughing and semi-finishing passes in ferrous and exotic-alloy applications. The insert size code is 12T3, placing it in a standard toolholder pocket used across a range of face mill and shoulder mill bodies. Typical use cases include production machining environments where tool life and chip control are critical factors.

Key Features

• Solid carbide substrate provides rigidity and wear resistance in demanding milling applications
• PVD TiAlN coating improves thermal stability and extends tool life when cutting steel, stainless steel, superalloys, and titanium
• 15-degree relief angle reduces cutting forces and minimizes workpiece heat buildup
• Parallelogram ADKT insert shape with insert size code 12T3 fits standard ADKT-series toolholders
• Maximum depth of cut of 1.063 inches supports both roughing and semi-finishing strategies
• Chip breaker designation 45 promotes reliable chip formation and evacuation

Compatibility

Designed as an OEM-style replacement insert for ADKT-series milling toolholders accepting size 12T3 parallelogram inserts with an inscribed circle in the 0.300 to 0.350 inch range and a thickness in the 0.125 to 0.150 inch range.

Installation Notes

Insert replacement is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before accessing the toolholder pocket. Use the correct torque wrench and insert screw specified by the toolholder manufacturer - do not overtighten or substitute fasteners. Inspect the pocket seat for debris or wear before seating the new insert to ensure proper contact and runout.
