Manufactured to the 490 series standard and identified by ANSI and ISO code 490R-08T316M-PH 1130, this insert features an AlTiCrN coating applied via PVD process, which delivers strong wear resistance at elevated cutting temperatures. The square insert geometry includes four right-hand cutting edges with a positive rake angle of 22 degrees and a corner radius of 0.0630 inches. It is intended for installation by machining professionals in production and job-shop environments working with high-volume or precision milling operations.\u003c\/p\u003e\u003cp\u003eThis insert is suited for milling steel, stainless steel, superalloys, titanium, and hard materials, corresponding to material grade designations P30, M15, and N15. The PH chip breaker geometry supports stable chip control across a range of cutting conditions. With a maximum depth of cut of 5.50 mm (0.2165 inches), this insert is appropriate for light to medium roughing and semi-finishing applications on vertical and horizontal machining centers where the 490 cutter series is employed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with AlTiCrN PVD coating for extended tool life in steel and stainless steel applications\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert with right-hand orientation, maximizing cost-per-edge value\u003c\/li\u003e\n\u003cli\u003ePositive 22-degree rake angle reduces cutting forces and heat generation at the workpiece\u003c\/li\u003e\n\u003cli\u003ePH chip breaker geometry supports controlled chip evacuation across multiple workpiece materials\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0630 inches (1.60 mm) reduces edge stress and improves surface finish at the corner\u003c\/li\u003e\n\u003cli\u003eScrew-held mounting method for secure, repeatable seating in compatible 490 series toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with SANDVIK COROMANT 490 series milling cutter bodies.

Use the correct Torx or hex key as specified by the cutter body manufacturer when tightening the clamping screw — do not over-torque. Inspect the cutter pocket seating surface and screw threads for damage or debris before seating the new insert. Rotate to a fresh cutting edge before replacing the insert entirely to maximize insert utilization.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 490\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI\/ISO Code\u003c\/strong\u003e: 490R-08T316M-PH 1130\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: 1130\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P30; M15; N15\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: PH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\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: 22 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief 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\u003eCutting Edge Style\u003c\/strong\u003e: Corner Rounded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0630 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3346 inches (8.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 08T316\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1299 inches (3.30 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.3346 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.3346 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2165 inches (5.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1102 inches\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel; Stainless Steel; Superalloys and Titanium; Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: 490\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: 0.015 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 6971889\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51733455601970,"sku":"6971889","price":344.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/574d2e07bbbcc4dcf238f973696ced3b_f27b15f5-98b8-4071-ad6b-a7acd54a7344.jpg?v=1788755603","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6971889-milling-insert-490r-08t316m-ph-1130","provider":"Voomi Supply","version":"1.0","type":"link"}
