Tool-flo 603600RAC50C Threading Insert Carbide AC50C

Product Description

The TOOL-FLO 603600RAC50C is a carbide threading insert designed for both internal and external thread-cutting operations on CNC lathes and manual turning centers. Built to the FLT-3R geometry in the Flo-Lock series, it carries an AC50C PVD coating applied to a C5/C6 carbide grade substrate. The insert cuts a standard 60-degree V-thread profile and handles an external pitch range of 6-20 TPI and an internal pitch range of 5-12 TPI. Right-hand cutting orientation makes it suitable for conventional threading passes on steel, alloy, and similar machinable materials. Machinists and CNC operators install this insert directly into compatible Flo-Lock toolholders without modification.

This insert fits threading applications in general metalworking shops, production machining environments, and maintenance-repair operations where consistent thread form and tool life are priorities. The AC50C grade with PVD coating is suited for threading ferrous and non-ferrous workpieces across the supported TPI range. Both internal and external thread forms are achievable with this single insert style, reducing tooling inventory requirements for shops running mixed threading work on lathes or turning centers.

Key Features

• Carbide substrate at material grade C5/C6 with AC50C PVD coating for wear resistance
• Cuts both internal and external 60-degree V-threads in a single insert style
• External pitch range: 6-20 TPI; internal pitch range: 5-12 TPI
• Right-hand cutting orientation for standard threading passes
• Tip-to-top height of 0.0980 inches and thickness of 0.1950 inches for precise toolholder seating
• Corner radius range of 0.0050 to 0.0080 inches for controlled thread root form

Compatibility

Designed for use in TOOL-FLO Flo-Lock series threading toolholders sized for insert size 3. Verify toolholder pocket geometry and clamping style before installation.

Installation Notes

A qualified machinist or CNC operator should install this insert with the machine spindle fully stopped and all energy sources locked out per standard LOTO procedures. Use the correct torx or hex key to seat and torque the clamping screw to the toolholder manufacturer specification - do not overtighten. Confirm insert orientation is right-hand before initiating the threading cycle, and verify thread pitch programming matches the insert TPI range before cutting.
