The insert carries a multi-layer CVD coating of Al2O3, TiCN, and TiN applied over a carbide substrate, providing thermal resistance and wear protection during interrupted and continuous turning operations. With an 80-degree diamond shape (Insert Shape Code C), a 0.5-inch inscribed circle, and a 0.03125-inch corner radius, this neutral-hand insert is sized for medium-duty turning passes. Licensed machinists and CNC operators working in precision manufacturing install this insert in standard CNMG-style toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is rated for primary use on superalloys and titanium alloys, material group S per ISO classification. The QM chip breaker geometry is designed to manage the tough, stringy chips characteristic of these materials. It fits standard CNMG 12 04 08 toolholder pockets and is interchangeable under ISO designation CNMG 12 04 08-QM S205. Typical applications include turning of aerospace components, medical implant stock, and high-temperature alloy parts where heat resistance at the cutting edge is critical. Each package contains one insert.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD-applied multi-layer coating: Al2O3, TiCN, and TiN for high-temperature wear resistance\u003c\/li\u003e\n\u003cli\u003eS205 grade optimized for superalloy and titanium workpiece materials (ISO material group S)\u003c\/li\u003e\n\u003cli\u003eQM chip breaker geometry engineered for tough, difficult-to-machine materials\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape with neutral hand — fits standard CNMG toolholder pockets\u003c\/li\u003e\n\u003cli\u003eFour usable cutting edges per insert, reducing per-edge tooling cost\u003c\/li\u003e\n\u003cli\u003eClamp and screw holding method compatible — versatile toolholder fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNMG 12 04 08-style toolholder pockets per ISO and ANSI CNMG 432 standards.

Use the appropriate torx or hex key specified by the toolholder manufacturer when tightening the clamp or screw — do not overtighten, as carbide inserts are brittle and can crack under excessive clamping load. Inspect the toolholder pocket seating surface for chips or debris before seating a new insert. Follow your facility safety procedures and the toolholder manufacturer guidelines for proper insert retention.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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: 80-degree Diamond (Shape Code C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: S205\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: Al2O3, TiCN, TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: QM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches (1\/2 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03125 inches (1\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.203 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees (Clearance Code N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\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 and Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Superalloy, Titanium (ISO Code S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG 12 04 08-QM S205\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.44 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 8003540\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51753016066354,"sku":"8003540","price":34.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f91efa65380335f7b3464d09f830f879_c192ec39-96c1-44aa-907a-5d1ebab28b8f.jpg?v=1788932155","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-8003540-cnmg432-qm-s205-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
