Coated with TiAlN via a PVD process, it carries a manufacturer grade of 1020 and an ISO\/ANSI code of R245-12 T3 E-KL 1020. The square insert geometry features four cutting edges, a positive 15-degree rake angle, and a 1.50 mm corner radius, making it well suited for controlled, efficient material removal in cast iron applications. This is a single-sided insert held in place by a screw-type clamping method.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in cast iron machining, corresponding to ISO material group K and material grade K05. The R245 series designation targets 90-degree shoulder milling and face milling setups in production environments. Typical installers are CNC machinists and toolroom technicians working on horizontal or vertical milling centers. The KL chip breaker geometry supports positive cutting action and chip control in cast iron workpieces. The insert size code is 12T3, with a maximum depth of cut of 6.50 mm (0.2559 inches).\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiAlN coating applied via PVD process for wear resistance in cast iron cutting\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges on a single-sided square insert body\u003c\/li\u003e\n  \u003cli\u003ePositive 15-degree rake angle reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eKL chip breaker for controlled chip formation in cast iron\u003c\/li\u003e\n  \u003cli\u003eScrew-mount insert holding method for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003e90-degree included angle geometry for shoulder and face milling compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Sandvik Coromant R245 series milling cutters.

Seat the insert fully against the pocket locating surfaces before torquing the clamping screw. Inspect the insert pocket for wear or debris before installing a replacement insert. Follow the milling cutter manufacturer's recommended torque procedure for the clamping screw to avoid insert movement or pocket damage during cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: R245\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 1020\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: K05\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 12T3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI\/ISO Code\u003c\/strong\u003e: R245-12 T3 E-KL 1020\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0591 inches (1.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1563 inches (3.97 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5276 inches (13.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.5276 inches (10.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1614 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2559 inches (6.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: KL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Corner Rounded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: R245\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5743879\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51737431933234,"sku":"5743879","price":453.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6546446b3a34d62a7ea5755f74b0f9f4.jpg?v=1788788485","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5743879-milling-insert-r245-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
