Komet 6260215002 Boring Insert TOHX140302G06 BK6425 Solid Carbide

Product Description

The KOMET 6260215002 is a solid carbide boring insert carrying the form designation TOHX140302G06 in grade BK6425. This indexable insert features a three-layer coating stack - TiCN base, Al2O3 mid-layer, and TiN top coat - engineered for wear resistance and thermal stability during internal boring operations. The 60-degree triangular geometry provides three usable cutting edges per insert. Key dimensional specs include a 0.2 mm corner radius, an 8.2 mm inscribed circle, a 3 mm thickness, and an 8-degree relief angle. It is installed by machinists and CNC operators performing precision bore finishing or semi-finishing on lathes and boring bars.

This insert is suited for internal diameter boring applications on CNC lathes, turning centers, and dedicated boring machines in both production and job-shop environments. The TiCN-Al2O3-TiN coating combination is commonly selected for machining steel, cast iron, and similar ferrous workpiece materials where controlled tool life and surface finish consistency are priorities. The 60-degree triangle geometry and 8-degree relief angle support positive-rake toolholder configurations typical in finish boring work.

Key Features

• Solid carbide substrate with TiCN, Al2O3, and TiN multilayer PVD/CVD coating for extended tool life
• 60-degree triangular insert geometry - three usable cutting edges per insert
• 0.2 mm corner radius for controlled surface finish in bore finishing passes
• 8.2 mm inscribed circle and 3 mm thickness per TOHX seat standards
• 8-degree relief angle supports positive clearance in precision boring applications
• Grade BK6425 formulated for demanding internal machining conditions

Compatibility

Designed as an OEM-style indexable replacement insert for boring bars and toolholders accepting TOHX140302 seat geometry in the BK6425 grade specification.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Always power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torx or clamp-style insert key specified by the toolholder manufacturer to secure the insert at the correct clamping torque per the holder documentation. Inspect the insert pocket and seating surface for chips or debris before seating the new insert.
