Kennametal 1623279 VBGT332HP KC5410 Carbide Turning Insert

Product Description

The KENNAMETAL 1623279 is a solid carbide turning insert in the VBGT332HP geometry, grade KC5410, designed for high-precision finishing of aluminum and non-ferrous metals. It features a 35-degree diamond (rhombic) shape with a positive rake angle of 15 degrees and a 5-degree relief angle, making it well-suited for light, accurate cuts with excellent surface finish. The insert carries a TiB2 PVD coating engineered for high wear resistance on non-ferrous workpiece materials. With a honed cutting edge and HP chip breaker, this insert delivers consistent chip control during finishing passes. It is sold individually but must be ordered in multiples of 5.

This insert is intended for finishing operations on non-ferrous metals, including aluminum alloys, copper, brass, and similar materials. It is rated for turning, facing, boring, back turning, and back boring applications. The screw-on holding method and VBGT insert style make it compatible with standard toolholders designed for that insert geometry. The 0.0492-inch maximum depth of cut and 0.0313-inch corner radius are optimized for tight-tolerance finishing rather than roughing work. Typical users include CNC machinists and toolroom operators working in production or job-shop environments.

Key Features

• 35-degree diamond insert shape with positive rake and positive side clearance for low cutting forces
• HP chip breaker geometry designed for finishing operations
• Honed cutting edge style for improved edge consistency on light finishing cuts
• 2 cutting edges per insert; screw-on holding method for secure, repeatable seating
• Multi-use geometry supports turning, facing, boring, back turning, and back boring

Compatibility

Designed for use in toolholders accepting VBGT-style screw-on inserts. Conforms to ANSI insert code VBGT332 and ISO insert code VBGT160408. Suitable for material grades C3 and C4 per industry classification.

Installation Notes

Installation is performed by a qualified machinist or CNC toolroom technician. Power down and lock out the machine before changing inserts. Seat the insert fully against the pocket before tightening the clamping screw to the toolholder manufacturer's specification. Inspect the insert pocket and seating surface for chips or debris before installation to avoid insert rocking or premature edge failure.
