Komet 6260332600 Boring Insert TOHX140304G12 BK8425 Solid Carbide

Product Description

The KOMET 6260332600 is a solid carbide boring insert carrying the form designation TOHX140304G12 in the BK8425 grade. It features a dual-layer coating - TiAlN with a TiN topcoat - designed to extend tool life in demanding boring applications where heat and abrasion are primary wear factors. The insert is a 60-degree triangular geometry with a 0.4 mm corner radius, an 8.2 mm inscribed circle, a 3 mm thickness, and an 8-degree relief angle. These geometry values make it well suited for finishing and semi-finishing passes in precision bored bores where tight tolerances and good surface finish are required.

This insert is intended for use in indexable boring bars and boring heads on CNC machining centers, lathes, and dedicated boring machines in metalworking environments. Typical applications include internal diameter boring of ferrous and non-ferrous materials in production machining, tool-room work, and repair operations. The TOHX140304G12 form and BK8425 grade combination targets scenarios where consistent edge performance across multiple index positions is critical. This is a trade item sold in a minimum order quantity of 10 pieces, with each package containing one insert.

Key Features

• Solid carbide substrate provides rigidity and wear resistance for precision boring
• TiAlN plus TiN dual-layer coating improves heat resistance and reduces built-up edge
• 60-degree triangular geometry delivers three usable cutting edges per insert
• 0.4 mm corner radius suited for finishing and semi-finishing operations
• 8-degree relief angle reduces flank contact and supports clean entry into bored features
• 3 mm insert thickness provides stable seating in compatible boring bar pockets

Compatibility

Designed for use in indexable boring tooling systems that accept the TOHX140304G12 insert geometry and seat dimensions. Verify pocket geometry, clamping style, and insert form against your boring bar or boring head specifications before ordering.

Installation Notes

Insert indexing and replacement should be performed by a qualified machinist or tooling technician with the machine in a full stop and all spindle energy isolated per your facility lockout/tagout procedure. Use the correct torque wrench and clamping screw specified by the boring bar manufacturer - do not substitute fasteners. Inspect the insert pocket for debris, wear, or damage before seating a new insert, as a contaminated or worn pocket will compromise edge accuracy and bore tolerances.
