It features a 55-degree diamond (rhombic) shape with a neutral hand orientation and a negative rake and side clearance configuration. The insert measures 11.63 mm in length with a 3\/8-inch inscribed circle and a 3\/64-inch corner radius. The PVD-applied multilayer AlTiN and AlCrN coating delivers extended tool life in demanding turning, facing, boring, back turning, and back boring operations. It is part of the KENNAMETAL KENLOC series and conforms to ANSI insert code DNMG333 and ISO insert code DNMG110412.\u003c\/p\u003e\u003cp\u003eThis insert is suited for roughing and medium machining applications on steel (ISO P workpiece material) and cast iron (ISO K workpiece material). The KCK20 grade provides high wear resistance against steel and a range from high wear resistance to moderate toughness against cast iron. It is held using a clamp or pin method, making it compatible with standard KENLOC-style toolholders used in CNC turning centers and manual lathes across both production and job-shop environments. The maximum depth of cut is 0.0492 inches (1.25 mm).\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePVD multilayer AlTiN and AlCrN coating for high wear resistance in steel and cast iron cutting\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape (DNMG) with chamfered and honed cutting edge style\u003c\/li\u003e\n\u003cli\u003e4 cutting edges per insert for extended insert life and lower per-edge cost\u003c\/li\u003e\n\u003cli\u003eUN chip breaker geometry optimized for roughing and medium machining operations\u003c\/li\u003e\n\u003cli\u003eClamp or pin holding method compatible with KENLOC-series toolholders\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO standards for broad toolholder interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENLOC-series toolholders accepting DNMG-style inserts with clamp or pin holding.

Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully against the pocket locating surfaces before engaging the clamp or pin to ensure proper geometry and cutting edge position. Inspect the insert pocket for wear or damage each time the insert is indexed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DNMG333\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DNMG110412\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: D - Diamond (Rhombic) 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCK20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN and AlCrN multilayer PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: UN (Roughing and Medium Machining)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 11.63 mm (0.9156 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 3\/64 inches (0.0469 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.150 inches (3.81 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0492 inches (1.25 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 Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P), Cast Iron (K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: K10, K25\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\u003eWeight\u003c\/strong\u003e: 0.2 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: 3757597\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730756600114,"sku":"3757597","price":198.19,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a01e7ac7d2a31a643999f811dc455656.jpg?v=1788722319","url":"https:\/\/voomisupply.com\/products\/kennametal-3757597-dnmg333un-kck20-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
