It delivers a 1.25 mm cutting width and a maximum depth of cut of 2.10 mm, making it well-suited for narrow grooving and parting operations on precision turned components. The insert is right-hand oriented and uses a screw-holding method for secure, repeatable positioning in compatible toolholders. Micrograin carbide construction supports edge integrity at elevated cutting speeds. This is a single-use insert intended for installation and replacement by machinist and turning-center operators in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for grooving operations on stainless steel and steel workpieces, covering ISO material codes M and P. It fits into the Series J toolholder system and is appropriate for CNC lathes and turning centers where controlled groove width and consistent depth of cut are required. The F chip breaker geometry is optimized for those material groups, promoting chip control in both light and moderate feed applications. It conforms to ISO 13399 standards, supporting tool data integration in CAM and tooling management systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.25 mm cutting width with a maximum depth of cut of 2.10 mm\u003c\/li\u003e\n  \u003cli\u003eSolid micrograin carbide substrate in manufacturer grade J740\u003c\/li\u003e\n  \u003cli\u003ePVD TiN coating for wear resistance on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eF chip breaker geometry for controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003eScrew-clamping insert holding method for rigid, repeatable seating\u003c\/li\u003e\n  \u003cli\u003eCompliant with ISO 13399 for tooling data interoperability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in TUNGALOY Series J grooving toolholders that accept JTGR-style inserts with a 3\/8 inch inscribed circle.
