Tool-flo 602600LAC3R Threading Insert FLT-2L AC3R Carbide

Product Description

The TOOL-FLO 602600LAC3R is a left-hand carbide threading insert in the Flo-Lock series, designed for both internal and external thread cutting operations. Manufactured to Grade AC3 with a PVD coating process, this insert handles external pitches from 8 to 36 TPI and internal pitches from 7 to 20 TPI, covering a wide range of threading applications on the shop floor. The 60-degree included angle suits unified thread forms. Machinists and CNC operators install this insert into compatible Flo-Lock toolholders for precise, repeatable thread generation on lathes and turning centers.

This insert is suited for threading operations in production machining environments where consistent thread quality is required across both internal and external profiles. The left-hand orientation makes it the correct choice for left-hand thread cutting applications. At insert size 2L with a thickness of 0.1500 inches, it fits into the corresponding Flo-Lock seat geometry. Carbide substrate with PVD coating provides wear resistance across a range of workpiece materials graded C2 and C3.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or removing inserts. Use the correct torx or hex key to the toolholder manufacturer's recommended seating procedure - do not overtighten the clamping screw. Confirm insert orientation and pitch selection against the job setup sheet before initiating a threading pass.
