It features a 55-degree diamond shape with a neutral hand orientation and a 0.10 mm (0.0039 inch) corner radius for sharp, controlled cuts. The insert carries a dual-layer TiAlN and AlCr2O3 coating applied via PVD process, delivering strong wear resistance and thermal stability at the cutting edge. With four usable cutting edges per insert, this grade 1125 tooling is built for demanding, high-productivity turning applications where edge sharpness and coating integrity are critical.\u003c\/p\u003e\u003cp\u003eThis insert is intended for turning stainless steel as its primary workpiece material, with secondary suitability for superalloys and titanium. It fits into T-Max P series toolholders that accept DNGG-style inserts with a clamp and pin holding method. The insert is appropriate for finishing and semi-finishing passes where a sharp cutting edge style and a tight geometry tolerance (G tolerance code) are required. Licensed machinists and CNC operators working in aerospace, medical, and industrial manufacturing will find this insert suited to challenging material groups M and S per ISO classification. The ISO code for this insert is DNGG 15 04 01-SGF 1125 with a SGF chip breaker geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e55-degree diamond insert shape (DNGG style) with sharp cutting edge and SGF chip breaker\u003c\/li\u003e\n\u003cli\u003eTiAlN and AlCr2O3 dual-layer PVD coating for heat and wear resistance in difficult-to-machine materials\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert for extended tool life and lower cost per edge\u003c\/li\u003e\n\u003cli\u003e0.10 mm corner radius supports fine surface finishes on stainless steel and superalloys\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method compatible with T-Max P series toolholders\u003c\/li\u003e\n\u003cli\u003eG tolerance code ensures tight insert-to-seat repeatability for consistent part dimensions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in T-Max P series toolholders accepting DNGG-style inserts with clamp and pin holding.

Power down and lock out the machine spindle before changing inserts. Inspect the insert pocket and shim for debris or damage before seating a new insert. Do not use damaged or chipped inserts, as a compromised cutting edge can cause unpredictable tool failure in hard-to-machine materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNGG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (55-degree included angle)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 1125\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: TiAlN and AlCr2O3\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: SGF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Sharp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.10 mm (0.0039 inches)\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\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\u003eMaximum Depth of Cut\u003c\/strong\u003e: 13.55 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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO Code M)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Superalloy and 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: DNGG 15 04 01-SGF 1125\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: 6851275\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51730909036850,"sku":"6851275","price":432.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d613d8a3c23db074af797ee32ab73657_572c392a-72d7-468e-aa5e-142687c4e0b3.jpg?v=1788724636","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6851275-turning-insert-dngg-1-2-inch-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
