Tool-flo 603600HCRAC22R Threading Insert Carbide 6-20 Tpi

Product Description

The TOOL-FLO 603600HCRAC22R is a carbide threading insert designed for both internal and external thread cutting operations. Built to the FLT-3R-HCB style in the Flo-Lock series, this insert covers a broad pitch range of 6-20 TPI for external threading and 5-12 TPI for internal threading, following the 60-degree V thread standard. The submicron carbide substrate is finished with a PVD coating in manufacturer grade AC22R, delivering wear resistance and edge integrity under continuous threading cycles. Licensed machinists and CNC lathe operators use this insert in production threading of fastener features, pipe threads, and precision mechanical components.

This insert is suited for threading applications in general machining, job-shop environments, and production CNC turning centers where a single insert must handle a wide TPI range cleanly. The right-hand configuration and HCB chipbreaker geometry help manage chip flow in both internal and external threading passes. It fits standard FLT-3R toolholders in the Flo-Lock insert system, making it a direct drop-in for shops already running that platform.

Key Features

• Carbide substrate with PVD coating, manufacturer grade AC22R, submicron material grade
• Covers 6-20 TPI external and 5-12 TPI internal thread pitch ranges in a single insert
• 60-degree V thread form, compatible with unified and metric-style thread profiles at that included angle
• HCB chipbreaker geometry for controlled chip evacuation on internal and external threading passes
• Right-hand cutting orientation; insert size 3 in the Flo-Lock FLT series
• Thickness of 0.1950 inches; tip-to-top height of 0.0980 inches; corner radius range 0.0050 to 0.0080 inches

Compatibility

Designed for use with FLT-3R-HCB Flo-Lock series toolholders that accept size 3 threading inserts with the FLT insert style.

Installation Notes

Threading inserts should be installed by a qualified machinist or CNC setup technician following the toolholder manufacturer's seating and clamping procedures. Ensure the machine spindle is fully stopped and the turret is indexed to a safe position before changing inserts. Use the correct torque wrench or clamping screw driver specified by the toolholder manufacturer - do not overtighten, as this can fracture the carbide insert. Verify insert seating and edge condition before resuming cutting operations.
