It carries a TiAlN coating applied via PVD process, which provides thermal resistance and edge wear protection during interrupted and continuous cuts. The insert features a 55-degree diamond shape with a neutral hand orientation, a 1\/2-inch inscribed circle, and a 1\/64-inch corner radius. With four cutting edges and a honed cutting edge style, the 4171827 is suited for general turning operations where consistent tool life across steel and difficult alloys is required. Licensed HVAC and trade professionals working in precision environments will recognize this as a multi-application indexable insert.\u003c\/p\u003e\u003cp\u003eThis insert is designed for use in turning, facing, boring, back turning, and back boring operations. Primary workpiece materials include steel, stainless steel, superalloys, and titanium, corresponding to ISO material groups P, M, and S. The negative rake geometry and FP chip breaker designation make it appropriate for both roughing and semi-finishing passes in production and job-shop environments where chip control across varying feed rates is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDNMG431FP geometry with 55-degree diamond insert shape and neutral hand\u003c\/li\u003e\n\u003cli\u003eKCU10 grade with TiAlN PVD coating for extended tool life on steel and superalloys\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert for cost-effective indexing\u003c\/li\u003e\n\u003cli\u003eFP chip breaker for reliable chip control across turning, facing, and boring operations\u003c\/li\u003e\n\u003cli\u003eNegative rake angle with honed cutting edge style reduces edge chipping on interrupted cuts\u003c\/li\u003e\n\u003cli\u003eCompliant with ANSI and ISO standards; ISO code DNMG150404FP\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENLOC-style toolholders that accept DNMG-style inserts with clamp and pin holding methods.

Power down the machine and engage all machine locks before indexing or replacing inserts. Inspect the toolholder pocket and locating pin for debris or wear before seating a new insert. Do not use inserts with visible edge damage, as chipped or cracked carbide can cause workpiece damage or machine hazard.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: DNMG431FP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DNMG150404FP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (55 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU10\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 1.2208 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.4065 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: FP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\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: Steel, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Turning, Facing, Boring, Back Turning, Back Boring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0243 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4171827\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51729308582194,"sku":"4171827","price":235.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e23f82ba7cf66a69926f47b48aebcc5_2a325bb4-b488-4e98-805a-100efa40ad66.jpg?v=1788702719","url":"https:\/\/voomisupply.com\/products\/kennametal-4171827-dnmg431fp-kcu10-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
