Tool-flo 603600CRAC50C Threading Insert 8-20 Tpi Carbide

Product Description

The TOOL-FLO 603600CRAC50C is a carbide threading insert engineered for both internal and external thread cutting operations. Designed in the FLT-3R-CB style with an AC50C PVD coating, this insert delivers consistent performance across a range of thread pitches from 8 to 20 TPI. The 60-degree included angle suits standard unified thread forms, while the CB chipbreaker geometry promotes controlled chip flow during threading passes. It is installed by machinists and toolroom technicians working with CNC lathes, manual lathes, and threading toolholders in production or job-shop environments.

This insert is suited for threading applications on a variety of materials where carbide grade C5 to C6 tooling is appropriate. It handles both internal and external threading in a single insert style, making it a practical choice for shops that need versatility across right-hand thread cutting operations. The Flo-Lock series design is intended for use in compatible Flo-Lock toolholders and boring bars used in precision threading setups.

Installation Notes

Threading inserts should be installed by a qualified machinist using the correct torque wrench and insert seating tool for the toolholder manufacturer specifications. Ensure the machine spindle is fully stopped and the toolholder is secured before swapping inserts. Inspect the insert pocket for chips or debris before seating the new insert. Do not use damaged or chipped inserts, as this can result in poor thread quality or workpiece damage.
