Tool-flo 602600LJ5R Threading Insert FLT-2L GP3 Left Hand

Product Description

The TOOL-FLO 602600LJ5R is a carbide threading insert designed for both internal and external thread-cutting operations on CNC lathes and manual turning equipment. This insert carries the GP3 manufacturer grade using a micrograin carbide substrate and is finished with a Titanium Nitride (TiN) coating applied via PVD process. The left-hand configuration suits reverse-spindle and left-hand thread applications. It covers an external pitch range of 8-36 TPI and an internal pitch range of 7-20 TPI, making it a versatile choice for a wide range of thread profiles on production floors and job shops.

The 602600LJ5R belongs to the Flo-Lock series and uses the FLT insert style with a 60-degree V-thread standard and a built-in chipbreaker (CB). It is suited for threading ferrous and non-ferrous materials in light to medium-duty turning setups. Machinists and toolroom operators use this insert for both inch-standard external fastener threads and matching internal bore threads where a left-hand insert geometry is required.

Compatibility

Designed for use in Flo-Lock series toolholders accepting FLT-style size 2 threading inserts. Confirm toolholder seat geometry and insert pocket specifications before installation.

Installation Notes

Threading inserts are installed and serviced by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench or insert key specified by the toolholder manufacturer when seating the insert clamp screw. Inspect the insert pocket and clamp for debris or wear before installing a new insert to ensure proper seating and thread accuracy.
