Tool-flo 612800RAC3R Carbide Threading Insert 8-36 Tpi

Product Description

The TOOL-FLO 612800RAC3R is a carbide threading insert designed for both internal and external thread cutting operations. It carries an AC3 manufacturer grade with a C2/C3 material grade and features a PVD-applied coated finish for extended tool life in demanding threading applications. The insert follows a 60-degree V thread standard and covers an external pitch range of 8-36 TPI and an internal pitch range of 7-20 TPI. Part of the Flo-Lock series, this right-hand insert is suited for machinists and toolroom professionals who require consistent thread geometry and reliable performance across production or job-shop environments.

This insert is intended for use in Flo-Lock series threading toolholders configured for right-hand cutting. It supports both internal and external threading in a single insert geometry, making it a practical choice for shops running a variety of thread profiles. The 60-degree included angle covers standard unified and metric V-thread forms. Its compact insert size 2 profile fits standard Flo-Lock holders used on CNC lathes and manual threading setups in metalworking applications.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Ensure the threading toolholder is properly seated and clamped in the turret or toolpost before indexing or replacing inserts. Power down and lock out the machine before handling inserts, as carbide edges are sharp. Follow the toolholder manufacturer's clamping torque guidance and verify insert seating before resuming cutting operations.
