Seco 02450388 Threading Insert CP500 Carbide 16 Tpi

Product Description

The SECO 02450388 is a carbide threading insert designed for internal thread cutting operations. Manufactured in the LCE080416UNR geometry with a CP500 grade coating, this insert handles UN-standard internal threads at 16 threads per inch with a 60-degree included angle. The PVD coating process over a micrograin carbide substrate provides wear resistance suited to the demands of precision threading. It is installed by machinists and toolroom technicians working with Mini Shaft series boring and threading toolholders in CNC and manual turning applications.

This insert is engineered for internal threading on UN-standard fastener profiles in right-hand configurations. The Mini Shaft series designation makes it appropriate for small-diameter internal threading work where toolholder clearance is limited. Typical applications include threading bores in components machined from steel, alloy, and similar materials where consistent thread form and surface finish are required across production or jobsite repair cycles.

Key Features

• CP500 grade with PVD coating for extended tool life in internal threading
• Micrograin carbide substrate for edge strength and dimensional consistency
• 60-degree included angle for UN-standard thread form compliance
• 16 TPI internal pitch for common fastener and bore threading work
• Right-hand cutting orientation, LCEX insert style
• Mini Shaft series compatibility for small-bore toolholder systems

Compatibility

Designed for use with Mini Shaft series internal threading toolholders accepting LCEX-style inserts. Specific toolholder compatibility should be verified against SECO toolholder documentation prior to ordering.

Installation Notes

Threading inserts of this type are seated and clamped by a qualified machinist following the toolholder manufacturer's clamping torque and seating procedures. Ensure the machine spindle is fully stopped and the toolholder is secured before insert exchange. Verify insert orientation and hand designation match the toolholder before initiating a threading cycle. Inspect the insert seat and clamping screw condition at each insert change to maintain consistent thread geometry.
