Kennametal 5653062 Ball Nose Milling Insert SP6519

Product Description

The KENNAMETAL 5653062 is a solid carbide ball nose milling insert in the XPNT series, designed for high-performance milling of steel, stainless steel, superalloys, and titanium. Carrying grade SP6519 with a PVD-applied TiAlN coating, the insert delivers wear resistance and thermal stability in demanding cutting environments. It features a positive rake geometry, an 11-degree relief angle, and a honed cutting edge for consistent, controlled chip formation. The flat-top chip breaker design supports efficient chip evacuation in finish and semi-finish milling passes. Licensed HVAC techs and machinists in CNC milling operations specify this insert for precision contouring and profiling work.

This insert is intended for use in CNC milling applications involving ferrous metals, stainless steel grades, and difficult-to-machine superalloys and titanium alloys. It is a single-sided, right-hand insert with two cutting edges and mounts via screw-holding method. The insert is compatible with the KENNAMETAL 5505VX cutter series. It conforms to both ANSI code XPNT050522RF and ISO code XPNT16160308RF, making it straightforward to cross-reference against toolholder specifications. Typical applications include contour milling, copy milling, and 3D profiling on CNC machining centers.

Key Features

• Positive rake geometry with 11-degree relief angle reduces cutting forces on the workpiece
• Honed cutting edge style improves edge stability and reduces micro-chipping
• Right-hand, single-sided design with 2 cutting edges and screw-mount retention
• Dual ANSI and ISO coded for straightforward cross-referencing and toolholder compatibility

Compatibility

Compatible with the KENNAMETAL 5505VX cutter series. Conforms to ANSI code XPNT050522RF and ISO code XPNT16160308RF. Designed for right-hand screw-mount toolholders accepting XPNT-series inserts.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Before indexing or replacing inserts, ensure the machine spindle is fully stopped, locked out, and the tool is secured in a fixture or vise to prevent rotation. Use the appropriate Torx or hex key to the toolholder manufacturer's specified procedure when seating the clamping screw. Inspect the insert pocket and seating surface for chips or debris prior to mounting to ensure proper seating and runout control.
