Iscar 6402448 Single Point Threading Tool Internal Carbide

Product Description

The ISCAR 6402448 is a solid carbide single point threading tool designed for internal thread cutting operations on CNC and manual lathes. It cuts right-hand threads with a 60-degree profile angle, covering a range of 24 to 36 TPI with a minimum thread diameter of 0.1969 inches (5.00 mm). The cutting depth reaches 0.5512 inches (14.00 mm), making it suitable for threading into deeper bores where clearance is limited. A TiN coating provides surface hardness and lubricity to extend cutting life. The shank diameter is 5.00 mm with an overall length of 30.00 mm. Machinists and toolroom operators use this insert-style threading tool for precision threading in small-diameter internal applications.

This tool is intended for internal threading in small-bore components such as hydraulic fittings, precision mechanical assemblies, and fluid system parts where tight dimensional tolerances are required. The 60-degree profile angle makes it compatible with unified and metric thread forms in that geometry. The 5.00 mm shank fits corresponding boring bar holders sized for small-diameter work. The right-hand thread direction suits standard lathe rotation for the majority of threading applications encountered in job shop and production environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in small-diameter boring applications
• TiN coating for improved surface hardness and reduced friction during threading cuts
• 60-degree profile angle covers unified and metric thread forms of matching geometry
• 24 to 36 TPI range with 0.1969 inch minimum thread diameter for fine-pitch small-bore work
• 0.5512 inch cutting depth with 0.02 inch projection from edge for controlled engagement
• Right-hand thread direction compatible with standard lathe rotation

Compatibility

Designed as an OEM-style replacement threading tool for 5.00 mm shank boring bar holders used in CNC and manual lathe internal threading setups.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians familiar with lathe tooling setup. Power down and lock out the machine before seating or removing the tool from the holder. Ensure the shank is fully seated and clamped securely to the correct torque specification for the holder being used. Verify thread profile, TPI setting, and depth of cut in the machine control before engaging the workpiece.
