Komet 6260233400 Boring Insert TOHX090204G06 BK8425 Solid Carbide

Product Description

The KOMET 6260233400 is a solid carbide boring insert carrying the industry designation TOHX090204G06 in the BK8425 grade. It features a dual-layer TiAlN and TiN coating applied over a solid carbide substrate, giving it strong resistance to heat and flank wear during internal boring operations. The insert is ground to a 60-degree triangular form with a 0.4 mm corner radius, a 5.6 mm inscribed circle, a 2.5 mm thickness, and an 8-degree relief angle. Machinists and toolroom technicians use this insert in precision boring heads and cartridge-style boring systems where tight bore tolerances are required.

This insert is suited for internal diameter boring in machining centers, CNC lathes, and dedicated boring machines across light industrial and production environments. The 60-degree triangle geometry and moderate corner radius make it a practical choice for fine to semi-finish boring passes in steel, cast iron, and similar ferrous workpiece materials. The BK8425 grade designation indicates a coated carbide formulation positioned for general-purpose cutting performance. It is typically installed and set up by machinists, toolroom technicians, or CNC setup personnel working in precision machining operations.

Key Features

• Solid carbide substrate with TiAlN and TiN dual-layer coating for elevated heat and wear resistance
• 60-degree triangular insert geometry (TOHX style) for internal boring applications
• 0.4 mm corner radius for fine to semi-finish bore surface quality
• 5.6 mm inscribed circle and 2.5 mm thickness for use in compact boring cartridges and heads
• 8-degree relief angle reduces cutting edge rubbing and supports clean chip evacuation
• BK8425 carbide grade suited for general-purpose ferrous and similar material boring

Compatibility

Designed as an OEM-style indexable boring insert for use in compatible TOHX-seat boring cartridges, boring heads, and insert holders accepting the TOHX090204 insert form factor.

Installation Notes

Indexable boring inserts must be seated by a qualified machinist or toolroom technician using the appropriate torx or hex key to achieve the correct clamping torque specified by the boring head manufacturer. Power down and lock out the machine spindle before indexing or replacing any insert. Inspect the insert pocket and clamping screw for wear or damage before installing a new insert. Do not exceed the cutting parameters specified by the tooling system manufacturer for the boring head in use.
