Tool-flo 602600LAC50C Threading Insert FLT-2L Carbide

Product Description

The TOOL-FLO 602600LAC50C is a carbide threading insert designed for cutting both internal and external threads in a wide range of machining applications. Built to the FLT-2L style in the Flo-Lock series, this insert features a 60-degree V thread form and a left-hand cutting orientation. It covers an external pitch range of 8-36 TPI and an internal pitch range of 7-20 TPI, making it a versatile option for shops running multiple thread standards on the same setup. The AC50C manufacturer grade with PVD coating delivers extended tool life on steel and harder workpiece materials. Machinists and CNC operators working in production or job-shop environments will find this insert well-suited to high-volume threading cycles.

This insert is used in turning centers and CNC lathes where threaded features are produced on external diameters or bored internal threads. It is suited for both roughing and finishing passes across 60-degree V-thread profiles. The left-hand orientation makes it the correct choice for left-hand thread applications that would otherwise require a dedicated tool setup. The Flo-Lock series design ensures secure seating in compatible toolholders, reducing the risk of insert movement during cutting.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or replacing any indexable insert. Verify the insert pocket is clean and free of chips before installation to ensure proper seating and avoid premature edge failure. Always confirm thread hand orientation and pitch selection against the part print before beginning a threading cycle.
