It carries the JTGR3075F insert style designation and is manufactured in the J740 grade with a PVD-applied TiN coating. The insert provides a 0.75 mm cutting width and a maximum depth of cut of 1.9 mm, making it suited for narrow, shallow grooving work where dimensional accuracy is critical. The right-hand orientation, screw-holding method, and Series J design make this a direct-fit choice for compatible TUNGALOY toolholding systems. Machinists and CNC turning specialists are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for grooving stainless steel and steel workpieces, corresponding to ISO material codes M and P. The micrograin carbide substrate and TiN finish support stable cutting performance in these demanding materials. It is applicable in production turning environments where consistent groove width and controlled chip formation are required. The F chip breaker geometry is optimized for these material groups. The insert meets ISO 13399 standards for cutting tool data representation, which supports integration with CAM and tool management software used in modern machine shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide substrate for rigidity and wear resistance in steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003ePVD-applied TiN coating for extended tool life and reduced built-up edge\u003c\/li\u003e\n  \u003cli\u003e0.75 mm cutting width with a maximum depth of cut of 1.9 mm for narrow grooving applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand orientation with screw holding method for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003eF chip breaker geometry tuned for stainless steel and steel ISO M and P material groups\u003c\/li\u003e\n  \u003cli\u003eCompliant with ISO 13399 cutting tool data standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with TUNGALOY Series J grooving toolholders that accept JTGR-style inserts secured by screw clamp.

Power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex key to seat the screw clamp to the toolholder manufacturer specification  -  do not overtighten. Inspect the insert pocket for chips or debris before seating the new insert to ensure proper contact and runout.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.75 mm (0.0295 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.9 mm (0.0748 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: JTGR3075F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: J740\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (PVD Process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 mm (0.0012 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 9.53 mm (3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 3.18 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 2 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Steel (ISO M, P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.009 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TUNGALOY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6804980\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TUNGALOY","offers":[{"title":"Default Title","offer_id":51959999070514,"sku":"6804980","price":428.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/93f7ba07665a4e941380cd9655411ebd.jpg?v=1789946032","url":"https:\/\/voomisupply.com\/products\/tungaloy-6804980-grooving-insert-jtgr3075f-j740-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
