Tool-flo 613800RJ5R Threading Insert FLTP-3R GP3 Carbide

Product Description

The TOOL-FLO 613800RJ5R is a carbide threading insert designed for both internal and external thread cutting operations. Built to the FLTP style in grade GP3 with a micrograin carbide substrate, this insert handles a 60-degree V thread form across a wide pitch range: 5-12 TPI internally and 6-20 TPI externally. A titanium nitride finish applied via PVD coating improves surface hardness and wear resistance, extending tool life in demanding threading applications. It is a right-hand insert in the Flo-Lock series, suited for use in CNC lathes and multi-spindle threading setups where consistent thread form and tight tolerances are required.

This insert is intended for production threading on CNC turning centers and manual lathes where both internal and external 60-degree V threads are cut in steel, stainless, and similar materials. The GP3 micrograin carbide grade with PVD titanium nitride coating suits medium to high cutting speeds in ferrous materials. Machinists and tooling setters in job shops and production facilities use this insert for high-volume threading where insert consistency across a lot is critical. With insert size 3 geometry, it fits standard FLTP-style toolholders in the Flo-Lock series.

Key Features

• Carbide substrate with GP3 micrograin grade for sharp, consistent cutting edges
• PVD titanium nitride coating for improved wear resistance and surface finish
• Cuts both internal threads (5-12 TPI) and external threads (6-20 TPI) in 60-degree V form
• Right-hand insert orientation for standard thread cutting setups
• FLTP style, insert size 3, compatible with Flo-Lock series toolholders
• Minimum corner radius of 0.005 inches and maximum of 0.008 inches for precise thread root geometry

Compatibility

Designed for use with FLTP-style Flo-Lock series threading toolholders sized for insert size 3. Verify holder compatibility with the TOOL-FLO Flo-Lock toolholder system before ordering.

Installation Notes

Installation is performed by a machinist or tooling technician during machine setup. Power down and lock out the CNC lathe or turning center before seating or replacing inserts. Use the correct torx or hex key per the toolholder manufacturer specification to secure the insert clamp without over-torquing. Inspect the insert pocket for chips or debris before seating a new insert to ensure proper contact and runout.
