It carries the KCM25 manufacturer grade and features a multilayer CVD coating of TiN, TiCN, and Al2O3 applied by MTCVD process, delivering a balance of high toughness on steel and moderate wear-resistance and toughness on stainless steel. The insert has an 80-degree diamond shape with a 5\/8-inch inscribed circle, a 1\/32-inch corner radius, and a negative rake and clearance geometry. The UP chip breaker is rated for roughing and medium machining. Licensed machinists and CNC operators install this insert in negative-seat toolholders designed for CNMG geometry.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for roughing and medium turning passes on steel, stainless steel, and superalloys including titanium. With four cutting edges and a neutral hand orientation, it fits standard CNMG clamp-and-pin style toolholders in production turning and job-shop environments. Its honed cutting edge style reduces chipping risk in interrupted cuts and on work-hardened surfaces. The UP chip breaker geometry controls chip evacuation across a broad feed and depth-of-cut range, making it practical for both lathe turning and CNC boring bar applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCM25 grade with multilayer CVD TiN \/ TiCN \/ Al2O3 coating for steel and stainless steel applications\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond (C) insert shape with negative rake and negative clearance for rigid, high-force roughing\u003c\/li\u003e\n  \u003cli\u003eUP chip breaker rated for roughing and medium machining on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eFour usable cutting edges per insert with neutral hand orientation\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style improves edge integrity on difficult-to-machine alloys\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin insert holding methods in CNMG-geometry toolholders\u003c\/li\u003e\n  \u003cli\u003eDual ANSI (CNMG542) and ISO (CNMG160608) designations for easy cross-referencing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in negative-seat CNMG toolholders that accept the ANSI size code 542 (ISO size code 160608) insert geometry using clamp or pin retention.

Before indexing or replacing inserts, confirm the machine spindle is stopped and all motion is locked out per shop lockout\/tagout procedures. Seat the insert fully into the pocket and verify the clamp or pin applies even clamping force before initiating a cut. Do not exceed the maximum depth of cut specified for the insert geometry, and inspect the cutting edge and chip breaker for wear or damage at each index.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMG542\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMG160608\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CNMG542UP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCM25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 16.12 mm (0.6346 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: 1\/32 inch (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: 1.25 mm (0.0492 inches)\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: 15 degrees negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N (Negative)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN \/ TiCN \/ Al2O3 multilayer CVD (MTCVD process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: CVD\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: UP (Roughing and Medium Machining)\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: 4\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 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\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C1, C2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 3761038\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743922684210,"sku":"3761038","price":290.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/674bf178938476a4734629f21c6c95fb.jpg?v=1788851341","url":"https:\/\/voomisupply.com\/products\/kennametal-3761038-cnmg542up-kcm25-turning-insert-80-diamond","provider":"Voomi Supply","version":"1.0","type":"link"}
