Iscar 6402438 Single Point Threading Tool Internal Carbide

Product Description

The ISCAR 6402438 is a solid carbide single point threading tool designed for internal thread cutting operations on CNC lathes and turning centers. It cuts right-hand internal threads with a 60-degree profile angle and handles a minimum thread diameter of 0.2362 inches (6.00 mm). The cutting depth reaches 0.5906 inches (15.00 mm), and the overall length is 1.1811 inches (30.00 mm). A TiCN and TiN dual-layer coating improves wear resistance and surface finish on threaded bores. The 6.00 mm shank diameter fits standard toolholders used in precision turning applications. Coolant-through capability helps clear chips and control heat during high-speed threading passes.

This tool is suited for internal threading of small-diameter bores in production and job-shop turning environments. It handles thread pitches from 1.25 mm, covering 16 to 20 TPI, making it appropriate for metric and unified thread forms commonly found in fastener, fluid-passage, and mechanical assembly components. It is installed by machinists and CNC operators working with lathes equipped for single point threading cycles. The compact geometry and short projection from edge of 0.03 inches (0.70 mm) support stable cutting in confined bore conditions.

Key Features

• Solid carbide construction for rigidity and wear resistance in threading applications
• TiCN and TiN dual-layer coating for extended tool life and reduced friction
• 60-degree profile angle compatible with standard unified and metric thread forms
• Coolant-through design to aid chip evacuation and thermal management
• Compact 0.03-inch projection from edge for stable cutting in small-diameter bores
• Right-hand thread direction for standard CNC lathe threading cycles

Compatibility

Designed as an OEM-style single point threading insert or tool for use in turning centers and CNC lathes equipped with 6.00 mm shank toolholding systems capable of internal threading operations.

Installation Notes

This tool is installed by qualified machinists or CNC operators. Confirm the toolholder bore and clamping mechanism match the 6.00 mm shank diameter before mounting. Ensure the machine spindle is at a complete stop and the machine is locked out before changing tooling. Verify coolant-through connections are properly seated to maintain chip control during threading cycles.
