Manufactured from carbide at material grade C5\/C6 and coated with Titanium Nitride via a PVD process at manufacturer grade GP50, this insert handles internal pitches from 5 to 12 TPI and external pitches from 6 to 20 TPI on a 60-degree V thread form. At size 3 with a thickness of 0.195 inches, it is built to the dimensional standards expected in precision threading operations on CNC lathes and threading equipment. Machinists and tool-room technicians working with ferrous and non-ferrous materials rely on this insert for consistent thread form accuracy.\u003c\/p\u003e\u003cp\u003eThis insert is suited for production threading environments where left-hand thread cutting is required on both internal bores and external diameters. The FLT insert style combined with the Flo-Lock series design provides secure seating in compatible toolholders. The CB chipbreaker geometry helps manage chip flow during threading passes, reducing the risk of chip interference in the cut zone. It is applicable in job shop, contract machining, and production floor settings across industries that require precise 60-degree unified or metric-style V-thread profiles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCarbide construction at material grade C5\/C6 for wear resistance in threading applications\u003c\/li\u003e\n\u003cli\u003eTitanium Nitride finish applied via PVD coating process at GP50 grade\u003c\/li\u003e\n\u003cli\u003eHandles internal pitches of 5-12 TPI and external pitches of 6-20 TPI\u003c\/li\u003e\n\u003cli\u003eLeft-hand cutting orientation for left-hand thread production\u003c\/li\u003e\n\u003cli\u003e60-degree V thread form for standard unified thread profiles, both internal and external\u003c\/li\u003e\n\u003cli\u003eCB chipbreaker geometry aids chip control during threading passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement threading insert for Flo-Lock series toolholders accepting FLT style, size 3 inserts with a 60-degree V thread form geometry.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis insert is installed and replaced by machinists or tool-room technicians following standard insert-change procedures for indexable threading toolholders. Ensure the machine spindle is fully stopped and all motion has ceased before removing or seating the insert. Use the appropriate torx or hex key as specified by the toolholder manufacturer to achieve proper clamping force without over-torquing the insert screw. Confirm correct insert orientation for left-hand cutting direction before beginning a threading pass.\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\u003eManufacturer Grade\u003c\/strong\u003e: GP50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5\/C6\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\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: 5-12 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Pitch\u003c\/strong\u003e: 6-20 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\u003eInsert Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.195 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip to Top of Insert\u003c\/strong\u003e: 0.0980 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: 0.24 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: 603600LN4C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TOOL-FLO","offers":[{"title":"Default Title","offer_id":67917829472562,"sku":"603600LN4C","price":289.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a99ff56cefccbaed3e77fb9910c40934.jpg?v=1791265616","url":"https:\/\/voomisupply.com\/products\/tool-flo-603600ln4c-threading-insert-gp50-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
