Tool-flo 602600LN4C Threading Insert GP50 Carbide 8-36 Tpi

Product Description

The TOOL-FLO 602600LN4C is a left-hand carbide threading insert designed for both internal and external thread cutting operations. Part of the Flo-Lock series, it is ground to a 60-degree V thread profile and carries a GP50 manufacturer grade with a C5/C6 material grade rating. A PVD-applied Titanium Nitride finish coating improves wear resistance and extends tool life in production threading applications. The insert covers an external pitch range of 8-36 TPI and an internal pitch range of 7-20 TPI. It weighs 0.08 pounds and is sized as an Insert Size 2 with a thickness of 0.1500 inches. Machinists and toolroom operators use this insert in CNC lathes and manual turning centers for precision thread forms.

This threading insert is suited for ferrous and non-ferrous threading work where left-hand thread profiles are required. The 60-degree included angle covers unified and metric-style V-thread forms across both internal and external applications. The chipbreaker geometry (CB designation) helps manage chip flow during threading passes, making it appropriate for interrupted cuts and through-hole threading in a production or job-shop environment. The Flo-Lock series is designed for indexable toolholders that accept this insert style and size.

Installation Notes

This insert is installed and replaced by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the toolholder is secured before indexing or replacing the insert. Use the appropriate torque wrench or insert-clamping tool specified by the toolholder manufacturer to seat the insert correctly. Verify thread pitch and hand orientation against the job requirement before beginning the threading operation.
