Tool-flo 603600RN4C Threading Insert GP50 Carbide 6-20 Tpi

Product Description

The TOOL-FLO 603600RN4C is a carbide threading insert designed for precision thread-cutting operations on both internal and external workpiece profiles. Manufactured to the FLT style in insert size 3 and grade GP50, it features a PVD coating applied over carbide substrate for extended tool life in demanding threading applications. The 60-degree V thread form covers internal pitches from 5 to 12 TPI and external pitches from 6 to 20 TPI, making it a versatile choice across a wide range of thread standards. This insert is right-hand orientation and belongs to the Flo-Lock series. Machinists and tooling technicians working in CNC lathe or manual turning environments are the primary users.

This threading insert is suited for shops producing threaded components in ferrous and non-ferrous materials where consistent thread form and surface finish are required. The Flo-Lock series is built for indexable threading toolholders that accept FLT-style inserts. It handles both internal and external threading in a single insert style, reducing the number of tooling SKUs a shop needs to stock for general-purpose thread-turning operations on a CNC or manual lathe.

Installation Notes

Threading inserts should be seated and torqued into the toolholder per the toolholder manufacturer specifications using the appropriate wrench or torque key. Power down and lock out the machine spindle before indexing or replacing inserts. Inspect the insert pocket and clamping screw for wear or damage before installing a new insert. Handle carbide inserts with care to avoid chipping the cutting edges prior to use.
