It carries the KC850 manufacturer grade and features a multilayer CVD coating consisting of TiC, TiCN, and TiN, which provides moderate wear resistance with sustained toughness across a wide range of workpiece materials. The insert is square in shape with a 90-degree included angle, a 3\/4-inch inscribed circle, a 3\/64-inch corner radius, and a neutral hand orientation. It is suited for medium machining chip breaker conditions and is held using a clamp or pin system. Licensed machinists and CNC operators install this insert as part of KENLOC series tooling setups.\u003c\/p\u003e\u003cp\u003eThis insert is rated for turning, facing, and boring operations. Primary workpiece materials include steel and stainless steel, with secondary capability in cast iron and special or super alloys. The negative rake and negative side clearance geometry deliver stable cutting action in medium machining passes. With 8 cutting edges per insert, the SNMP643 geometry offers strong cost-per-edge value in high-volume production. It conforms to both ANSI and ISO standards, with an ISO insert code of SNMP190612, making it interchangeable with tooling specified to either standard. This insert is sold individually but carries a minimum order quantity of 5 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC850 grade with multilayer CVD TiC, TiCN, and TiN coating for wear resistance and toughness\u003c\/li\u003e\n\u003cli\u003eSquare insert shape with 90-degree included angle and 3\/4-inch inscribed circle\u003c\/li\u003e\n\u003cli\u003e3\/64-inch corner radius (0.0469 inches) for controlled surface finish in medium cuts\u003c\/li\u003e\n\u003cli\u003e8 cutting edges per insert for extended tool life and reduced cost per edge\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp and pin insert holding methods\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO standards; ISO code SNMP190612\u003c\/li\u003e\n\u003cli\u003eRated for turning, facing, and boring on steel, stainless steel, cast iron, and super alloys\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENLOC series turning toolholders that accept SNMP-style inserts with a clamp or pin holding method.

The machine spindle must be stopped and all axes must be at a safe position before indexing or replacing inserts. Use the appropriate torque wrench and manufacturer-specified fastener for the KENLOC toolholder to secure the clamp or pin. Inspect the insert seat and clamp for wear or debris before seating a new insert, as contamination in the pocket can cause insert fracture or poor surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: SNMP643\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: SNMP190612\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC850\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: TiC, TiCN, TiN (Multilayer CVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square (S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Width\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inch (0.2500 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: 0.3125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Common (Medium Machining)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Pin\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Special and Super Alloys\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\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: 0.05 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: 1161324\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744858800434,"sku":"1161324","price":368.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7d88f7138134e38a9a1fd953a6ccd7d2.jpg?v=1788861645","url":"https:\/\/voomisupply.com\/products\/kennametal-1161324-snmp643-kc850-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
