Built to the FLTK-3L insert style and manufactured from carbide with a Titanium Nitride finish applied via PVD coating, this insert carries a GP50 manufacturer grade and a C5\/C6 material grade rating. It covers a 60-degree V thread standard and handles external pitches from 10 to 44 TPI and internal pitches from 9 to 24 TPI. The Flo-Lock series design provides secure seating and consistent thread form across a wide pitch range. Machinists and toolroom technicians select this insert for precision threading on CNC lathes and manual turning centers.\u003c\/p\u003e\u003cp\u003eThis insert is suited for threading operations in production and job-shop environments where left-hand thread profiles are required on external diameters and internal bores. The 60-degree included angle makes it compatible with unified and standard V-thread forms. It fits machines set up for size-3 Flo-Lock toolholders and is appropriate for use on materials in the C5 and C6 carbide application range, including steel, cast iron, and similar ferrous workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand insert orientation for left-hand thread cutting on external and internal features\u003c\/li\u003e\n\u003cli\u003eExternal pitch range: 10 to 44 TPI; internal pitch range: 9 to 24 TPI\u003c\/li\u003e\n\u003cli\u003e60-degree V thread form for unified and standard thread profiles\u003c\/li\u003e\n\u003cli\u003eGP50 grade carbide substrate with PVD-applied Titanium Nitride coating for wear resistance\u003c\/li\u003e\n\u003cli\u003eInsert size 3, Flo-Lock series for positive lock seating in compatible toolholders\u003c\/li\u003e\n\u003cli\u003eTip-to-top dimension of 0.1410 inches; thickness of 0.1950 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Flo-Lock series size-3 threading toolholders that accept the FLTK-3L insert style.
