Tool-flo 603600HCRAC50C Threading Insert Carbide 6-20 Tpi

Product Description

The TOOL-FLO 603600HCRAC50C is a carbide threading insert designed for precision thread cutting on CNC lathes and turning centers. Built in the FLT style with an HCB chipbreaker, this insert handles both internal and external threading operations on a single tool platform. The AC50C grade features a PVD coating over a C5/C6 carbide substrate, delivering wear resistance and edge integrity across a 6-20 TPI external pitch range and 5-12 TPI internal pitch range. It carries a 60-degree V thread form to standard inch thread geometry. Machinists and tool-and-die professionals specify this insert where consistent thread quality and extended tool life are the priority.

This insert fits into the Flo-Lock series toolholding system and is suited for right-hand threading operations in job shop and production turning environments. It addresses both internal and external threading, making it a dual-use option when equipped in compatible Flo-Lock toolholders. Typical applications include threading steel and alloy materials in the C5/C6 material grade range. The HCB chipbreaker geometry promotes chip control during interrupted or continuous threading passes, which is particularly useful on multi-pass thread cycles common in production turning.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before seating or removing the insert. Torque the insert clamp or screw per the toolholder manufacturer's specification for the FLT seat style. Inspect the insert seat and clamp for wear or debris before each insert change to ensure proper seating and edge repeatability.
