Kennametal 1560781 VPGR331 KC5410 Carbide Profiling Insert

Product Description

The KENNAMETAL 1560781 is a solid carbide profiling and turning insert in the VPGR331 geometry, manufactured to the KC5410 grade with a PVD-applied TiB2 coating. The insert features a parallelogram shape with a 35-degree included angle, a positive rake angle of 10 degrees, and an 8-degree relief angle. The inscribed circle measures 3/8 inches (0.3750 inches), thickness is 3/16 inches (0.1875 inches), and the corner radius is 0.0156 inches (0.40 mm). Designed for precision profiling and turning operations, this insert is installed by machinists and CNC operators working with non-ferrous metal workpieces. It is held in place by a clamp and offers two cutting edges per insert.

This insert is suited for profiling and turning applications on non-ferrous metals, corresponding to ISO material group N (N05, N10, N15, N20). It fits the Top Notch series tooling system and conforms to standards VPGR331 and ISO code VCGR160404. Typical applications include contour turning and form profiling on aluminum, copper, and similar non-ferrous alloys in both production and precision machining environments. It is a neutral-hand insert, making it adaptable to either orientation depending on toolholder configuration.

Key Features

• Solid carbide construction with PVD TiB2 coating for wear resistance on non-ferrous workpieces
• VPGR331 parallelogram geometry with 35-degree included angle for profiling and contouring
• Positive rake (10 degrees) and 8-degree relief angle reduce cutting forces
• Two cutting edges per insert for extended tool life
• Clamp-held mounting method for secure, repeatable positioning
• Maximum depth of cut of 0.2179 inches supports medium-depth profiling passes

Compatibility

Designed for use in Top Notch series toolholders accepting VPGR331 inserts. Conforms to ISO standard VCGR160404. Intended for non-ferrous metal machining applications in tooling systems designed for clamp-held parallelogram inserts.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before seating or replacing the insert. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer — do not substitute clamp hardware. Inspect the insert pocket and clamp for chips or wear before seating a new insert to ensure proper contact and runout.
