Kennametal 2229646 Turning Insert DNGG432FS KC5010

Product Description

The KENNAMETAL 2229646 is a solid carbide turning insert with a DNGG432FS geometry, coated with TiAlN via a PVD process under the KC5010 manufacturer grade. It carries a 55-degree diamond (rhombic) shape, a neutral hand orientation, and a 0.5 inch inscribed circle with a 1/32 inch (0.0313 inch) corner radius. The insert measures 15.50 mm (approximately 1.22 inches) in length and 3/16 inch (0.1875 inch) in thickness. Designed for finishing operations, it is secured by clamp and pin holding methods. Licensed machinists and CNC turning specialists install this insert in KENLOC-compatible toolholders for high-precision material removal.

This insert is optimized for finishing cuts across steel, stainless steel, cast iron, superalloys, and titanium, corresponding to ISO workpiece material codes P, M, K, N, and S. Typical applications include turning, facing, boring, back turning, and back boring on both CNC lathes and manual turning centers. The FS chip breaker geometry is engineered for finishing passes where surface finish and dimensional accuracy are the primary objectives. Maximum depth of cut is 1.25 mm (0.0492 inch), confirming its role as a light, precision insert rather than a roughing tool.

Key Features

• TiAlN coating applied via PVD process delivers high wear resistance across steel and stainless steel applications
• 55-degree diamond insert shape provides a sharp, low-contact-angle cutting geometry suited to finishing passes
• FS chip breaker geometry engineered for controlled chip formation during light finishing cuts
• Four cutting edges per insert maximize tool utilization and reduce per-edge cost
• KC5010 grade rated for high wear resistance to moderate wear resistance and toughness across P, M, and K material groups
• Complies with ANSI (DNGG432) and ISO (DNGG150408) standards for broad toolholder compatibility

Compatibility

Designed as a direct-fit replacement for KENLOC series toolholders accepting DNGG432 geometry inserts per ANSI and ISO standards. Compatible workpiece materials include steel, stainless steel, cast iron, aluminum, superalloys, and titanium as specified by the manufacturer.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or replacing the insert. Use a torx or hex key appropriate to the KENLOC clamp system and verify the pin and clamp are fully engaged before resuming cuts. Inspect the insert seat for chips or debris that could affect seating accuracy and dimensional repeatability.
