Iscar 6402436 Single Point Threading Tool Internal Carbide

Product Description

The ISCAR 6402436 is a solid carbide single point threading tool designed for internal thread cutting on CNC lathes and turning centers. It cuts right-hand threads with a 60-degree profile angle and covers a range of 20 to 24 threads per inch (TPI), with a minimum threading diameter of 0.1969 inches (5.00 mm). The cutting depth reaches 0.5512 inches (14.00 mm), making it suitable for threading at depth inside bores and through-holes. A titanium nitride (TiN) coating improves surface hardness and wear resistance. Machinists and CNC operators working in precision threading applications install this tool in standard 5.00 mm shank holders.

This threading tool is intended for internal threading operations in small-bore applications, particularly where tight diameter constraints apply. The 0.1969-inch minimum thread diameter makes it appropriate for fine-pitch work on small components such as fittings, fastener inserts, hydraulic bodies, and precision machined parts. It is suited for use in production and job-shop environments where consistent thread form and repeatability are required. The right-hand thread direction and 60-degree profile make it compatible with standard unified and metric thread forms within the supported pitch range.

Key Features

• Solid carbide construction for rigidity and wear resistance in internal threading
• 60-degree profile angle covers standard unified and metric thread forms
• 20 to 24 TPI range with 1.00 mm pitch for fine-thread applications
• TiN coating improves tool life and surface finish on threaded features
• 0.0200-inch (0.60 mm) projection from edge for controlled engagement in small bores
• No coolant-through design — suitable for dry or externally applied coolant setups

Compatibility

Designed for use in 5.00 mm shank toolholders compatible with ISCAR single point threading tool systems for internal right-hand thread cutting operations.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the toolholder is clean and undamaged before seating the tool. Verify shank diameter and projection measurements match your toolholder specification before clamping. Follow the toolholder manufacturer torque and clamping guidelines — do not overtighten set screws on carbide shanks.
