Tool-flo 603600RJ5R Threading Insert FLT-3R GP3 Carbide

Product Description

The TOOL-FLO 603600RJ5R is a carbide threading insert designed for both internal and external thread cutting operations on CNC lathes and manual turning equipment. Manufactured in the FLT style with a GP3 micrograin carbide grade, it features a Titanium Nitride (TiN) finish applied via PVD coating process. The insert covers an external pitch range of 6-20 TPI and an internal pitch range of 5-12 TPI, making it a versatile choice across a wide range of threading applications. The 60-degree V-form included angle covers the most common unified and metric thread profiles. A built-in chipbreaker (CB) helps manage chip flow in production environments.

This insert is suited for production threading on ferrous and non-ferrous materials in both job-shop and high-volume CNC turning settings. The right-hand cutting geometry and Flo-Lock series design make it a standard choice for machinists and toolroom professionals running external thread forms on shafts, fasteners, and fittings, as well as internal threading on bored workpieces. The PVD TiN coating extends tool life and reduces built-up edge in general-purpose threading cuts.

Compatibility

Designed as an OEM-style replacement insert for Flo-Lock series threading toolholders accepting size-3 FLT-style inserts. Confirm toolholder insert pocket specifications before ordering.

Installation Notes

Threading inserts should be seated and torqued into a compatible Flo-Lock toolholder per the toolholder manufacturer's specifications. Always index or replace worn inserts before resuming cutting to avoid thread-form errors or workpiece damage. Ensure the machine spindle is fully stopped and the toolholder is secured before handling or changing inserts. Verify TPI selection against the required thread standard before beginning a threading pass.
