It belongs to the Flo-Lock series and carries a GP3 manufacturer grade using a micrograin carbide substrate. A titanium nitride finish is applied via PVD coating, improving surface hardness and wear resistance. The insert follows a 60-degree V thread standard with a chipbreaker (CB) geometry, making it suitable for a wide range of thread pitches from 4 to 20 TPI on external profiles and 4 to 12 TPI on internal profiles. Machinists and toolroom technicians use this insert on CNC lathes and manual turning centers for precision thread-forming work.\u003c\/p\u003e\u003cp\u003eThis insert is intended for shops performing high-volume or precision threading where consistent thread geometry and tool life are priorities. The FLT-style insert seats into compatible Flo-Lock toolholders. Left-hand orientation makes it the correct choice for left-hand thread applications or specific machine spindle configurations that require it. It is suited to both production environments and job-shop threading operations across a range of ferrous and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGP3 grade micrograin carbide substrate for improved edge strength and wear resistance\u003c\/li\u003e\n\u003cli\u003ePVD-applied titanium nitride coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eCuts both internal (4-12 TPI) and external (4-20 TPI) threads\u003c\/li\u003e\n\u003cli\u003e60-degree V thread form compatible with unified and similar thread standards\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert orientation for appropriate application fitment\u003c\/li\u003e\n\u003cli\u003eChipbreaker (CB) geometry to aid chip control during threading cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in TOOL-FLO Flo-Lock series toolholders accepting FLT-style inserts.

Power down and lock out the machine before seating or removing inserts. Use the appropriate torque wrench and insert screw to secure the insert per the toolholder manufacturer's specifications  -  do not overtighten by hand. Inspect the insert seat for chips or debris before each installation to ensure proper seating and thread accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: FLT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Flo-Lock\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: GP3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: 60 Degree V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal and External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Pitch\u003c\/strong\u003e: 4-12 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Pitch\u003c\/strong\u003e: 4-20 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: CB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Titanium Nitride\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip to Top of Insert\u003c\/strong\u003e: 0.1280 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.2550 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Corner Radius\u003c\/strong\u003e: 0.0050 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Corner Radius\u003c\/strong\u003e: 0.0080 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TOOL-FLO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 604600LJ5A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TOOL-FLO","offers":[{"title":"Default Title","offer_id":67910965494066,"sku":"604600LJ5A","price":349.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b6e27cd067e726ac56fa951c8371bfd.jpg?v=1791202297","url":"https:\/\/voomisupply.com\/products\/tool-flo-604600lj5a-threading-insert-gp3-carbide-4-20-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
