Iscar 6402403 Left Hand Carbide Grooving Tool

Product Description

The ISCAR 6402403 is a solid carbide internal grooving tool designed for left-hand cutting operations in bore grooving applications. Built from solid carbide construction, it delivers the rigidity and wear resistance needed for precision groove cutting in small-diameter bores. The tool features a 6 mm shank diameter, a 2 mm groove width, and a full-radius profile, making it well suited for producing consistent, clean grooves in tight internal bore conditions. Machinists and tooling specialists working on CNC lathes and turning centers rely on this tool for reliable, repeatable performance in precision machining environments.

This grooving tool is intended for internal grooving operations where bore access is limited. It accommodates a minimum hole diameter of 4.70 mm and reaches a maximum hole depth of 37 mm. The full-radius geometry produces a radiused groove bottom without secondary operations. With an overall length of 62 mm and a projection of 2.49 mm, the tool fits into compact toolholding setups used in high-precision turning work on ferrous and non-ferrous materials.

Key Features

• Solid carbide construction for rigidity and extended tool life in internal grooving
• Left-hand cutting direction for specific bore orientations and toolholder configurations
• Full-radius profile produces a radiused groove bottom in a single pass
• 2 mm groove width with a 1 mm radius for precise groove geometry
• 6 mm shank diameter fits standard small-bore toolholding systems
• Maximum hole depth of 37 mm suits deep internal grooving applications

Compatibility

Designed as an OEM-style replacement or direct-fit tooling component for small-bore internal grooving applications on CNC lathes and turning centers accepting a 6 mm shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with CNC turning center setup. Ensure the machine spindle is fully stopped and the machine is placed in a safe lockout state before changing or seating tooling. Secure the shank firmly in the toolholder to the holder manufacturer's clamping specifications to prevent deflection during cutting. Verify cutting direction compatibility with the toolholder and machine turret orientation before beginning any grooving operation.
