Designated by ANSI and ISO code R390-17 04 04M-PM 1130, this single-sided parallelogram insert features a positive rake angle of 17 degrees and a PVD-applied AlTiCrN coating under grade 1130. The PM chip breaker geometry supports stable chip control across a range of cutting conditions. With a maximum depth of cut of 15.70 mm and 2 cutting edges, this insert delivers consistent performance in demanding metal removal applications. It is installed using a screw-holding method and is designed for right-hand cutting.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling steel, stainless steel, non-ferrous metals, superalloys, titanium, and hard materials, corresponding to material application codes P, M, N, S, and H. It is used in both roughing and finishing operations where positive-rake geometry reduces cutting forces on the workpiece. Typical applications include face milling, shoulder milling, and ramping operations on machining centers in production and job-shop environments. The R390 cutter series compatibility makes it a direct-fit replacement for tooling already set up with that system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePVD AlTiCrN coating on grade 1130 solid carbide substrate for wear resistance across multiple workpiece materials\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle of 17 degrees reduces cutting forces and heat generation at the cutting edge\u003c\/li\u003e\n  \u003cli\u003ePM chip breaker geometry for controlled chip evacuation during face and shoulder milling\u003c\/li\u003e\n  \u003cli\u003eCorner rounded cutting edge style with a corner radius of 0.0157 inch (1\/64 inch) for edge stability\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 15.70 mm (0.6181 inch) for productive material removal\u003c\/li\u003e\n  \u003cli\u003eSingle-sided design with 2 cutting edges; screw-clamped for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003eCompliant with ANSI and ISO insert designation standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in SANDVIK COROMANT R390 series milling cutter bodies.

Always index or replace inserts with the machine spindle fully stopped and locked out per applicable safety procedures. Inspect the cutter pocket and seating surfaces for chips or debris before seating a new insert, as contamination affects runout and tool life. Wear cut-resistant gloves when handling carbide inserts, as edges are sharp.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: R390\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI\/ISO Code\u003c\/strong\u003e: R390-17 04 04M-PM 1130\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Parallelogram\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: 1130\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiCrN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PM\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: 17 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 19 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Corner Rounded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0157 inch (1\/64 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 4.76 mm (0.1875 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 9.60 mm (0.3780 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.6181 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3780 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 15.70 mm (0.6181 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1614 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P30, M15, N15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Non-Ferrous Metal, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\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: 0.02 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: 6971767\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51750501417266,"sku":"6971767","price":369.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4b2bfb782665e4a57a9c9ac560ca12a5_106b0df2-8d8b-4eb1-85d6-4a3c4c2d348c.jpg?v=1788915932","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6971767-r390-milling-insert-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
