It belongs to the Flo-Lock series and carries a GP50E manufacturer grade, placing it in the C5\/C6 carbide material grade range. The insert features a 60-degree V-thread form, a chipbreaker geometry, and a Titanium Nitride finish applied via PVD coating. At 0.255 inches thick with a tip-to-top height of 0.128 inches, this insert is built for right-hand threading on lathes and thread-turning setups. Installation and tooling changes are handled by machinists and CNC turning professionals.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for thread turning applications in both production and job-shop environments. The FLT insert style and Flo-Lock series designation make it compatible with TOOL-FLO Flo-Lock threading toolholders designed for that insert family. The 4-20 TPI range covers coarse and fine unified thread forms commonly encountered in general machining, fastener production, and component threading. The right-hand orientation and 60-degree included angle make it a standard fit for the majority of inch-series threading work on CNC and manual lathes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide construction with GP50E grade, rated C5\/C6 for threading applications\u003c\/li\u003e\n  \u003cli\u003ePVD-applied Titanium Nitride coating for wear resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eCovers both internal and external thread cutting from 4 to 20 TPI\u003c\/li\u003e\n  \u003cli\u003e60-degree V-thread form with integrated chipbreaker geometry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut orientation; FLT insert style for Flo-Lock toolholders\u003c\/li\u003e\n  \u003cli\u003eCorner radius range of 0.005 to 0.008 inches for controlled thread root form\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with TOOL-FLO Flo-Lock series threading toolholders that accept FLT-style inserts.
