The insert is manufactured from solid carbide and features a multilayer CVD coating consisting of TiN, MT-TiCN, and Al2O3 applied via MTCVD process. This combination delivers high toughness on steel and moderate wear resistance with toughness when cutting stainless steel. The 80-degree diamond (rhombic) shape provides a strong cutting geometry, and the MR chip breaker is rated for roughing and medium machining. Machining technicians and CNC operators working in production environments install these inserts into KENLOC-style toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, and boring applications on steel, stainless steel, and superalloys including titanium. The KCM35 grade targets ISO P and M workpiece material categories, making it a practical choice for general production machining and interrupted or variable-condition cuts where toughness is a priority. The negative rake geometry and honed cutting edge contribute to edge stability under heavier chip loads. The neutral hand orientation provides installation flexibility across right- and left-hand toolholder setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCM35 grade with multilayer CVD coating: TiN, MT-TiCN, and Al2O3 for toughness and wear resistance\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape with negative rake and negative side clearance\u003c\/li\u003e\n\u003cli\u003eMR chip breaker optimized for roughing and medium machining operations\u003c\/li\u003e\n\u003cli\u003e4 cutting edges per insert for extended tool economy\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.25 inches for productive material removal\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with standard KENLOC clamp and pin holding systems\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO standards (ANSI: CNMG432MR, ISO: CNMG120408MR)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENLOC-series indexable toolholders that accept CNMG432 inserts held by clamp or pin methods.

Use the appropriate torque wrench and clamp hardware specified for the KENLOC toolholder to secure the insert; do not overtighten by hand. Inspect the insert pocket and seating surface for chips or debris before seating a new insert. Follow the toolholder manufacturer's guidelines for clamp or pin retention to ensure proper insert contact and repeatability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMG432MR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMG120408MR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCM35\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\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\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.508 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches (1\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.25 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: MR (Roughing and Medium Machining)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN, MT-TiCN, Al2O3 (Multilayer CVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: MTCVD\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: 20 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\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\u003eWeight\u003c\/strong\u003e: 0.011 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\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: 5403018\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51750651232562,"sku":"5403018","price":182.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3b3f631dbea890a1f1f08ce656896bfa.jpg?v=1788917845","url":"https:\/\/voomisupply.com\/products\/kennametal-5403018-cnmg432mr-kcm35-turning-insert-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
