It features a CVD-applied multilayer coating of TiCN and Al2O3 that provides wear resistance and thermal stability during continuous and interrupted cuts. The diamond-shaped insert body carries a 55-degree included angle, a negative rake geometry, and a chamfered and honed cutting edge style. With four usable cutting edges and a 3\/64-inch corner radius, this insert delivers consistent performance across roughing and finishing passes on steel and cast iron workpieces. Licensed HVAC and metalworking shops running KENLOC-style toolholders will find this insert a direct fit.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, boring, back turning, and back boring operations in production and job-shop environments. It targets steel and cast iron as primary workpiece materials, making it appropriate for general machining of shafts, flanges, housings, and similar components. The RP chip breaker geometry manages chip evacuation at a range of feed rates, helping maintain process control in both light and medium-depth cuts. Machinists and CNC operators in industrial and trade settings install this insert as part of standard tooling maintenance cycles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer TiCN and Al2O3 coating for thermal and abrasion resistance\u003c\/li\u003e\n\u003cli\u003eDiamond insert shape with 55-degree included angle and negative rake for stable cutting forces\u003c\/li\u003e\n\u003cli\u003eRP chip breaker geometry supports turning, facing, boring, back turning, and back boring\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert extend tooling value across production runs\u003c\/li\u003e\n\u003cli\u003eChamfered and honed cutting edge reduces micro-chipping on entry and exit\u003c\/li\u003e\n\u003cli\u003eCompatible with both clamp and pin insert holding methods\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for KENLOC-series toolholders accepting DNMG-style diamond inserts with a 1\/2-inch inscribed circle. Industry standard number DNMG433RP and ISO code DNMG150412RP confirm fitment against standard toolholder catalogs. Meets ANSI and ISO insert standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInsert seating and clamping should be performed with the machine fully powered down and the spindle locked. Use the appropriate torque wrench and KENLOC clamp hardware to secure the insert without over-tightening the clamp screw. Inspect the pocket seat for chips or debris before seating a new insert, as contamination can cause insert rocking and premature edge failure. This work is typically performed by a CNC machinist or toolroom technician following the toolholder manufacturer's seating procedure.\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: DNMG433RP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DNMG150412RP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCP25C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\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: 5 degrees\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\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 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\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 3\/64 inch (0.0469 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\u003eChip Breaker\u003c\/strong\u003e: RP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN \/ Al2O3 (CVD Multilayer)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\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, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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: 0.03 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: 7026656\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732024492338,"sku":"7026656","price":186.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2bcbb37b8ad94624f80a2d16258f702f.jpg?v=1788738278","url":"https:\/\/voomisupply.com\/products\/kennametal-7026656-dnmg433rp-kcp25c-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
