Tool-flo 603600CLAC50C Threading Insert 8-20 Tpi Flo-lock

Product Description

The TOOL-FLO 603600CLAC50C is a carbide threading insert designed for both internal and external thread cutting operations. It belongs to the Flo-Lock series and carries the FLT-3L-CB insert style with an AC50C manufacturer grade, placing it in the C5/C6 material grade range. The insert features a PVD coating process and a chipbreaker geometry (CB) that helps manage chip flow during threading. It covers external pitches from 8 to 20 TPI and internal pitches from 8 to 12 TPI, with a 60-degree included angle conforming to NV thread standard. This insert is installed by machinists and CNC operators working on threading applications in manufacturing and precision machining environments.

The 603600CLAC50C is suited for threading operations on materials where a C5/C6 carbide grade and PVD coating provide adequate wear resistance and edge life. The left-hand configuration makes it appropriate for left-hand thread production on both internal bores and external diameters. It is commonly used in production turning centers and CNC lathes where consistent thread form and chip control are priorities. The Flo-Lock series geometry is matched to standard threading toolholders designed for this insert style and size.

Key Features

• FLT insert style in size 3L with chipbreaker (CB) geometry for controlled chip flow
• AC50C grade carbide with PVD coating for extended tool life in threading applications
• Covers external pitch range of 8 to 20 TPI and internal pitch range of 8 to 12 TPI
• 60-degree included angle conforming to NV thread standard for internal and external thread forms
• Left-hand insert orientation for left-hand thread cutting
• Corner radius range of 0.0050 to 0.0080 inches for controlled thread root geometry

Compatibility

Designed for use in Flo-Lock series threading toolholders that accept FLT-3L style inserts. Confirm toolholder insert pocket specification before ordering to ensure proper seating and clamping.

Installation Notes

Threading inserts should be installed by qualified machinists or CNC operators following the toolholder manufacturer's seating and torque guidelines. Power down and lock out the machine before changing inserts. Inspect the insert pocket and clamping screw for wear or damage before seating a new insert. Never use a damaged or improperly seated insert, as this can cause insert fracture or thread form errors.
