Part of the KENDEX series, this insert carries the KYS25 manufacturer grade and features a multilayer CVD coating of Al2O3 and TiCN, delivering high wear resistance with moderate toughness. The full-radius round shape provides 8 available cutting edges, maximizing tool life between index cycles. The insert measures 0.5 inches in inscribed circle diameter and 0.3125 inches in thickness. It is installed via clamp-style holding and suits turning, facing, and boring operations. Licensed machinists and CNC operators working in aerospace and high-temperature alloy applications are the primary users.\u003c\/p\u003e\u003cp\u003eThis insert is intended for machining superalloys and titanium, material group code S, in applications demanding consistent wear resistance under demanding thermal and mechanical loads. The flat-top chip breaker geometry and T-Land cutting edge style control chip flow during continuous or interrupted passes. Typical install scenarios include finish and semi-finish turning on horizontal or vertical CNC lathes as well as boring bar applications where a round insert profile is required. The maximum depth of cut is 0.1665 inches. The neutral hand configuration makes it adaptable to both left- and right-hand toolholders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSiAlON ceramic base material with multilayer CVD Al2O3 and TiCN coating for superalloy and titanium machining\u003c\/li\u003e\n\u003cli\u003e8 usable cutting edges per insert for extended tool economy\u003c\/li\u003e\n\u003cli\u003eFull-radius round insert shape (ANSI code RNG45) compatible with clamp-style toolholders\u003c\/li\u003e\n\u003cli\u003eFlat-top chip breaker with T-Land edge for controlled chip formation at negative rake angles\u003c\/li\u003e\n\u003cli\u003eRated for turning, facing, and boring in a single insert style\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO standards; ISO code RNG120700\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard production insert for clamp-style round-insert toolholders conforming to ANSI insert code RNG45 and ISO insert code RNG120700.

Power down and lock out the machine spindle before indexing or replacing inserts. Use a calibrated torque wrench and the toolholder manufacturer's specified clamp screw when securing the insert to avoid cracking the ceramic substrate. Inspect the insert seat and clamp for debris or damage before each index; ceramic inserts are brittle and will fracture if seated improperly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: RNG (Round)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: RNG45\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: RNG120700\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Ceramic (SiAlON)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KYS25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Al2O3 and TiCN Multilayer CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1665 inches\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: Flat Top\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: T-Land\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Negative Rake)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Turning, Facing, Boring\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\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: 4129576\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51737226936626,"sku":"4129576","price":213.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f04a8109a55544f93b43505421571348.jpg?v=1788785797","url":"https:\/\/voomisupply.com\/products\/kennametal-4129576-round-ceramic-turning-insert-kys25","provider":"Voomi Supply","version":"1.0","type":"link"}
