Iscar 6402444 Internal Single Point Threading Tool

Product Description

The ISCAR 6402444 is a solid carbide single point threading tool designed for internal thread milling operations on small-diameter bores. It cuts right-hand threads with a 60-degree profile angle, covering a range of 36 to 48 threads per inch (TPI) with a minimum threading diameter of 0.1575 inches. The tool has an overall length of 1.1811 inches and a cutting depth of 0.5906 inches. A TiCN and TiN dual-layer coating provides wear resistance and lubricity during high-speed threading passes. This tool is intended for use by machinists and toolroom professionals working on precision internal threading applications.

This threading tool is suited for internal threading of small bores in ferrous and non-ferrous materials on CNC lathes and machining centers. The 0.1575-inch minimum threading diameter makes it appropriate for fine-pitch, tight-bore applications common in precision component manufacturing, instrument parts, and threaded insert preparation. The right-hand thread direction and 60-degree profile angle are standard for unified and metric thread forms in this pitch range.

Key Features

• Solid carbide construction for rigidity and wear resistance in internal threading
• Covers 36 to 48 TPI range with a 60-degree profile angle
• TiCN and TiN coating for extended tool life and reduced friction
• 0.1575-inch minimum threading diameter for small-bore applications
• Right-hand thread direction, standard for unified and metric fine-pitch threads
• 0.02-inch projection from edge for controlled depth placement

Compatibility

Designed as an OEM-style replacement or direct-fit threading tool for CNC lathes and machining centers that accept solid carbide single point threading inserts with a 4.00 mm shank diameter.

Installation Notes

Installation and setup should be performed by a qualified machinist. Ensure the machine spindle is fully stopped and locked out before mounting or changing the tool. Verify shank diameter compatibility with the toolholder bore before seating the tool. Coolant-through is not supported on this tool; use external coolant or cutting fluid directed at the cutting zone as needed per shop practice.
