Iscar 6403301 Threading Insert Carbide Partial Profile 60 Degree

Product Description

The ISCAR 6403301 is a carbide threading insert designed for external thread cutting on CNC lathes and turning centers. Manufactured to the TIP 2MT-0.14 IC908 specification, it features a partial profile 60-degree included angle and a 1.11 mm pitch (23 TPI) cutting geometry. The IC908 grade substrate is PVD-coated for wear resistance during high-speed threading operations. The MT chipbreaker design supports controlled chip flow in Cut Grip series toolholders. This insert is sold individually and is intended for use by machinists and CNC operators in production and job-shop environments.

This insert is suited for external threading applications on a range of workpiece materials where a partial profile 60-degree thread form is required. It is compatible with Cut Grip series toolholders that accept Size 2 TIP-style inserts. Typical applications include threading operations on steel and alloy components in precision machining environments. The 1.11 mm pitch (23 TPI) makes it appropriate for metric and equivalent unified thread profiles at that pitch specification.

Key Features

• IC908 PVD-coated carbide grade for extended tool life in external threading
• Partial profile 60-degree thread form, 1.11 mm pitch (23 TPI)
• MT chipbreaker for effective chip control during threading passes
• Corner radius of 0.14 mm (0.0059 inches) for precise thread root geometry
• Cutting tip width of 2.40 mm (0.0945 inches)
• Conforms to ISO 13399 tooling data standards

Compatibility

Designed for use with Cut Grip series Size 2 TIP-style threading toolholders. Confirm toolholder seat geometry and insert size designation before installation.

Installation Notes

Threading inserts of this type are installed and serviced by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Seat the insert fully and evenly in the toolholder pocket and torque the clamping screw according to the toolholder manufacturer specification. Inspect the insert edge condition before each use and replace at the first sign of chipping or wear to avoid thread form errors.
