Tool-flo 613400RN4C Threading Insert GP50 10-44 Tpi

Product Description

The TOOL-FLO 613400RN4C is a carbide threading insert in the Flo-Lock series, designed for precision thread cutting on both internal and external profiles. Manufactured to grade GP50 with a material classification of C5/C6, this insert features a Titanium Nitride (TiN) finish applied via PVD coating process. The 60-degree V-thread geometry supports a wide pitch range, covering 9-24 TPI for internal threading and 10-44 TPI for external threading. Right-hand cutting orientation and a compact insert size of 3 make it a reliable choice for production threading operations in machining environments.

This insert is suited for threading applications in CNC turning centers and manual lathes where consistent thread form and tool life are priorities. The broad TPI range accommodates a variety of standard 60-degree unified and metric-compatible thread profiles, making it useful across job shop and production machining settings. It is typically installed by machinists and tooling technicians working on ferrous and non-ferrous materials in precision part manufacturing.

Key Features

• PVD-applied Titanium Nitride coating for extended cutting tool life and reduced friction
• 60-degree included angle supports standard V-thread forms for internal and external threading
• Wide pitch coverage: 9-24 TPI internal, 10-44 TPI external
• Right-hand insert orientation in Flo-Lock series toolholder system
• Minimum corner radius of 0.0020 inches, maximum of 0.0040 inches for precise thread tip geometry

Compatibility

Designed for use with TOOL-FLO Flo-Lock series threading toolholders accepting FLTF-style inserts, size 3. Compatible with both internal and external threading applications conforming to 60-degree V-thread standards.

Installation Notes

Threading inserts should be installed by qualified machinists or tooling technicians following the toolholder manufacturer's clamping specifications. Power down and lock out the machine spindle before changing inserts. Inspect the insert pocket and clamping mechanism for debris or wear before seating the new insert. Handle carbide inserts with care to avoid chipping the cutting edges prior to use.
