It features a multilayer MTCVD-applied TiCN and Al2O3 coating that delivers moderate wear resistance combined with toughness across a broad range of cutting conditions. The insert has a 5\/8-inch (0.6250-inch) inscribed circle, a 90-degree square shape, a 1\/4-inch thickness, and a 1\/32-inch (0.0313-inch) corner radius. With 8 usable cutting edges and a neutral hand orientation, it suits high-utilization production environments where insert cost-per-edge matters. Licensed machinists and CNC operators handling steel and cast iron work will find this insert a direct fit in KENLOC-series toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is designed for turning, facing, and boring operations where roughing and medium machining chip loads are common. Primary workpiece materials are steel and cast iron, with the KCP25 grade also rated for aluminum and non-ferrous applications at moderate wear-resistance and toughness levels. The RN chip breaker geometry supports interrupted and continuous cuts at moderate feed rates. The maximum depth of cut is 0.0492 inches (1.25 mm), making it appropriate for medium stock removal passes rather than light finishing work. It is secured using clamp or pin holding methods compatible with standard SNMG-style toolholders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSNMG542RN geometry with 90-degree square insert shape and negative rake angle for robust edge stability\u003c\/li\u003e\n\u003cli\u003eKCP25 grade with multilayer MTCVD TiCN and Al2O3 CVD coating for steel and cast iron cutting\u003c\/li\u003e\n\u003cli\u003e8 cutting edges per insert for reduced tooling cost per edge in production turning\u003c\/li\u003e\n\u003cli\u003eRN chip breaker supports roughing and medium machining chip-load ranges\u003c\/li\u003e\n\u003cli\u003eNeutral hand insert accepts clamp or pin holding in KENLOC-series and compatible SNMG toolholders\u003c\/li\u003e\n\u003cli\u003eChamfered and honed cutting edge style balances edge strength with thermal resistance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENLOC-series toolholders accepting SNMG-style inserts.

Seat the insert firmly against all pocket surfaces before torquing the clamping screw or securing the pin to the toolholder manufacturer specification. Inspect the pocket for chips or debris before seating a new edge; a contaminated pocket will rock the insert and accelerate edge chipping. Verify depth-of-cut and feed parameters do not exceed the 0.0492-inch maximum depth of cut for this insert geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: SNMG542\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: SNMG150608\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square (90 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Width\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inches (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inches (0.0313 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2500 inches (6.35 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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees (Negative side clearance)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Negative)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: RN (Roughing \/ Medium Machining)\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\u003eGrade\u003c\/strong\u003e: KCP25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN and Al2O3 (Multilayer MTCVD CVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade Classifications\u003c\/strong\u003e: C2, C3, C6, C7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Cast Iron, Aluminum and Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Clamp and Pin\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\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.3 pounds\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: 5\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: 3753529\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733711749426,"sku":"3753529","price":257.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d09d4a2e6624fe00181754aa1edff8db.jpg?v=1788758669","url":"https:\/\/voomisupply.com\/products\/kennametal-3753529-snmg542rn-kcp25-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
