Manufactured to ISO code 4.21508R666, this insert carries the K110M grade designation and features a bright, uncoated finish suited for applications where coating is not required or where sharp edge retention is the priority. It measures 0.197 inches thick with an inscribed circle of 0.591 inches and an overall length of 0.413 inches. The right-hand orientation and single-sided design are key factors for proper seating and consistent performance across the cutting cycle. Installation is performed by licensed machinists and tooling professionals in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for milling cast iron and non-ferrous metals, corresponding to material grade codes K and N in the ISO classification system. It fits applications where controlled chip formation and edge sharpness are more critical than wear coating, such as finishing passes on aluminum, brass, or gray cast iron. The screw-holding method ensures secure clamping in compatible insert pockets. With a series designation of 4.21 and an ISO code of 4.21508R666, it is selected by tooling engineers and machinists setting up face mills, shoulder mills, or other indexable milling bodies that accept this insert geometry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTrigon insert shape with positive rake for reduced cutting forces on cast iron and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eK110M solid carbide grade, bright and uncoated for sharp edge retention\u003c\/li\u003e\n  \u003cli\u003eRight-hand insert orientation, single-sided configuration\u003c\/li\u003e\n  \u003cli\u003eScrew-held mounting method for secure, repeatable positioning in the insert pocket\u003c\/li\u003e\n  \u003cli\u003eInscribed circle of 0.591 inches (15.00 mm) with thickness of 0.197 inches\u003c\/li\u003e\n  \u003cli\u003eISO code 4.21508R666 for straightforward cross-referencing with tooling catalogs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in indexable milling tool bodies that accept the 4.21508R666 insert geometry with a screw-clamping system.

Use the correct torque wrench and insert screw specified by the tooling body manufacturer to seat the insert properly — do not hand-tighten only. Inspect the insert pocket for wear, debris, or damage before seating a new insert, as a compromised pocket will affect runout and surface finish. Dispose of worn carbide inserts in accordance with local regulations for carbide and metallic waste.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: 4.21508R666\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 4.21508\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Trigon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: K110M\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: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.197 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.591 inches (15.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.413 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.197 inches (0.20 mm nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade Code\u003c\/strong\u003e: C2, C3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 4.21\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 666\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.028 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291601\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: 1191265\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51729487298866,"sku":"1191265","price":604.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/73bc2a51c641a56eada57444e234e295.jpg?v=1788705181","url":"https:\/\/voomisupply.com\/products\/kennametal-1191265-trigon-milling-insert-k110m-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
