Tool-flo 612600RAC3R Threading Insert Carbide 14-44 Tpi

Product Description

The TOOL-FLO 612600RAC3R is a carbide threading insert in the Flo-Lock series, designed for both internal and external thread cutting operations. The insert carries a manufacturer grade of AC3 with a PVD coating process applied to a carbide substrate, delivering consistent edge performance in threading applications. It cuts 60-degree V-form threads and covers an external pitch range of 14-44 TPI and an internal pitch range of 12-24 TPI. The right-hand orientation and insert size 2 designation make this a standard selection for machinists and toolroom technicians working on lathes and CNC turning centers.

This insert is suited for general threading work on both internal and external thread profiles in production and job-shop environments. The Flo-Lock insert style FTLK seats into compatible Flo-Lock toolholders. The wide TPI range makes it practical for cutting coarse through fine threads in a single insert style, reducing the number of inserts needed on the bench. Licensed machinists and CNC operators are the primary installers of this tooling.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist following the toolholder manufacturer's torque and clamping guidelines. Ensure the machine spindle is fully stopped and locked out before changing inserts. Inspect the toolholder pocket for chips or wear that could affect insert seating and thread accuracy. Handle carbide inserts with care to avoid chipping the cutting edge prior to use.
