It carries ISO designation CNMG 12 04 12-PR 4425 and features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN over a solid carbide substrate. The 80-degree diamond insert shape and manufacturer grade 4425 make this insert well-suited for continuous and semi-interrupted cuts in steel and cast iron. With a neutral hand orientation, it fits standard CNMG toolholders without directional limitation. Machinists and CNC operators install this insert as a direct replacement when cutting edges are worn.\u003c\/p\u003e\u003cp\u003eThis insert is intended for turning operations where steel is the primary workpiece material and cast iron is the secondary material. The PR chip breaker geometry controls chip formation across a range of depths of cut and feed rates typical in production turning. It is appropriate for both roughing and finishing passes depending on parameters selected at the machine. The T-Max P series is a commonly used Sandvik Coromant platform found in job shops and production facilities running high-volume steel turning programs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance and thermal protection\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (Insert Shape Code C) provides a strong cutting edge and good workpiece access\u003c\/li\u003e\n\u003cli\u003ePR chip breaker geometry for controlled chip evacuation in steel turning\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation fits standard CNMG toolholder pockets\u003c\/li\u003e\n\u003cli\u003e4 usable cutting edges per insert for extended tool life per unit\u003c\/li\u003e\n\u003cli\u003eClamp and screw holding method compatibility for secure seating in the pocket\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard CNMG toolholders accepting a 1\/2-inch inscribed circle insert.

Power down and lock out the machine spindle before indexing or replacing an insert. Inspect the toolholder pocket seat and clamping hardware for wear or damage before seating a new insert. Do not use damaged clamping screws, as improper seating can lead to insert fracture or toolholder damage during cutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG 12 04 12-PR 4425\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80-degree included angle)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4425\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiN (CVD process)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 inches \/ 12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.19 mm (0.0469 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inches \/ 4.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2030 inches (5.16 mm)\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 Holding Method\u003c\/strong\u003e: Clamp, Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.54 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.74 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.43 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 7860723\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51734282961202,"sku":"7860723","price":260.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/adbec394d4f86a78adae52f8cabc07dc_1921fd02-78f1-4aff-8395-0a3325eb0f5d.jpg?v=1788762316","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7860723-turning-insert-cnmg433-pr-4425","provider":"Voomi Supply","version":"1.0","type":"link"}
