Manufactured to the GTL-3 insert style with an IC354 PVD-coated carbide grade, this insert delivers controlled chip formation during cut-off work. The 3.1 mm cutting width and 8-degree left-hand lead angle make it well suited for applications where directional chip flow and edge entry angle are critical to surface finish and tool life. It uses a clamp-style holding method and fits toolholders in the Self-Grip series. The 0.20 mm corner radius reduces stress concentration at the cutting edge on moderate-tolerance workpieces.\u003c\/p\u003e\u003cp\u003eThis insert is intended for cut-off and deep grooving operations in production turning environments. It is appropriate for use on ferrous and non-ferrous materials within the C5 and C6 material grade range. Machinists and CNC operators in job shops, production floors, and maintenance shops typically specify this insert for repetitive parting work where consistent width and clean shoulder geometry matter. The left-hand orientation suits specific toolholder configurations where the insert must approach the workpiece from the left-hand direction.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGTL-3 insert style with 3.1 mm cutting width for precise parting and grooving\u003c\/li\u003e\n\u003cli\u003eIC354 PVD-coated carbide grade rated for C5 and C6 material groups\u003c\/li\u003e\n\u003cli\u003e8-degree left-hand lead angle for directional chip control during cut-off\u003c\/li\u003e\n\u003cli\u003e0.20 mm corner radius for reduced edge stress on finished surfaces\u003c\/li\u003e\n\u003cli\u003e7-degree relief angle supports clearance geometry at the cutting edge\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding method for secure, repeatable seating in Self-Grip series toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ISCAR Self-Grip series toolholders that accept GTL-3 insert seat size 3 clamp-style cutoff inserts with a left-hand orientation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician with the machine powered down and spindle locked before changing inserts. Seat the insert fully into the Self-Grip clamp pocket and confirm the clamp is torqued to the toolholder manufacturer specification before resuming operation. Inspect the insert seat for chips or debris before installation to prevent seating errors that cause premature edge failure. Do not use this insert in toolholder styles other than those specified for the GTL seat size and clamp method.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: GTL-3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 3\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: IC354\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 3.10 mm (0.1220 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 8 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.20 mm (0.0079 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Self-Grip\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Cut-off\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6091684\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51748242293042,"sku":"6091684","price":263.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ed7f7e4eee6a3f771e1a3d4cea384d61.jpg?v=1788890951","url":"https:\/\/voomisupply.com\/products\/iscar-6091684-cutoff-insert-gtl-3-3-1mm-left-hand-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
