Kennametal 1623272 TCGT21505HP KC5410 Carbide Turning Insert

Product Description

The KENNAMETAL 1623272 is a solid carbide turning insert in the TCGT21505HP geometry with KC5410 grade designation. It features a PVD-applied TiB2 (titanium diboride) coating engineered for high wear resistance when machining aluminum and other non-ferrous metals. The insert measures 11.00 mm (0.4331 inches) in length with a 1/4-inch (0.2500-inch) inscribed circle and a 0.0079-inch corner radius. A positive rake angle of 15 degrees and a honed cutting edge style combine to promote clean chip evacuation and tight surface finishes on finishing operations. Licensed machinists, CNC operators, and tooling specialists working with non-ferrous materials will find this insert suited for light, high-speed passes.

This insert is designed for finishing operations on non-ferrous metals, particularly aluminum. Its HP chip breaker promotes controlled chip flow at higher speeds and lighter depths of cut, with a maximum depth of cut of 1.25 mm (0.0492 inches). The screw-on holding method provides positive clamping in compatible TCGT-style toolholders. Typical applications include turning, facing, and boring operations on CNC lathes and turning centers in production or job-shop environments. The three available cutting edges per insert extend usable tool life before replacement is required.

Key Features

• PVD TiB2 coating for high wear resistance on aluminum and non-ferrous workpiece materials
• Positive rake angle (15 degrees) and honed cutting edge reduce cutting forces and improve surface finish
• HP chip breaker geometry optimized for finishing operations
• Three cutting edges per insert for extended tool utilization
• Screw-on insert holding method for secure, repeatable seating
• Meets ANSI and ISO standards; ANSI code TCGT21505, ISO code TCGT110202

Compatibility

Designed for use in TCGT-style screw-on toolholders compatible with the TCGT21505 insert size code. Suitable for turning, facing, and boring applications on non-ferrous metals including aluminum. Verify toolholder compatibility using the ANSI insert code TCGT21505 or ISO insert code TCGT110202 before ordering.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and all motion has ceased before indexing or replacing inserts. Use the appropriate torx or hex key to secure the clamping screw to the toolholder manufacturer's specified procedure without over-torquing the insert pocket. Inspect the insert seat and clamping screw for wear or debris before seating a new insert to ensure proper contact and repeatability.
