Kyocera TBN02322 Cbn Turning Insert DNGA433ME4 KBN05M

Product Description

The KYOCERA TBN02322 is a cubic boron nitride (CBN) turning insert in the DNGA433ME4 KBN05M configuration, designed for high-speed machining of hardened ferrous materials. It features a 55-degree diamond (rhombic) insert shape, a 1/2-inch inscribed circle, and a 3/64-inch corner radius. The KBN05M grade carries a MEGACOAT PVD coating engineered for high wear resistance on hardened workpiece materials in the H01 and H10 material grade range. With four cutting edges and a honed cutting edge style, this insert delivers consistent edge life in demanding turning applications. It is installed by machinists and tooling professionals in CNC turning centers and manual lathes.

This insert is suited for external turning, boring, and copying operations on hardened steels and similarly hard materials where conventional carbide inserts reach their limits. The DNGA form factor uses a clamp and pin holding method with a negative rake and negative side clearance geometry, making it appropriate for rigid, stable setups on production turning equipment. It conforms to both ANSI and ISO standards, with ANSI code DNGA433 and ISO code DNGA150412, giving it broad compatibility across DNGA-style toolholders used in industrial machining environments.

Key Features

• Cubic boron nitride (CBN) insert material with MEGACOAT PVD coating for extended tool life on hardened workpieces
• KBN05M grade optimized for hardened materials, material grades H01 and H10
• 55-degree diamond insert shape (DNGA) with four usable cutting edges
• Honed cutting edge style reduces microchipping in interrupted and continuous hard-turning cuts
• Clamp and pin holding method with negative rake geometry for rigid, chatter-resistant setups
• Compliant with ANSI and ISO insert standards for drop-in toolholder compatibility

Compatibility

Designed for use in DNGA-style toolholders conforming to ANSI insert code DNGA433 and ISO insert code DNGA150412. Suitable for external turning, boring, and copying applications on hardened materials. Multi-use tool compatible with standard clamp and pin retention systems.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. De-energize and lock out the machine before seating or indexing the insert. Verify the toolholder pocket and seating surfaces are clean and free of chips before clamping. Follow the toolholder manufacturer's specified clamping torque and retention hardware requirements; do not substitute clamp styles not rated for DNGA negative-geometry inserts.
