It carries manufacturer grade IC508 and features a PVD-applied dual-layer TiCN and TiN coating for wear resistance and extended tool life in interrupted and continuous turning operations. The insert has a positive rake angle of 3 degrees, a 7-degree relief angle, and a corner radius of 0.0039 inches (0.10 mm). Right-hand orientation and a clamp-style holding method make it compatible with standard MiniCham toolholders. This insert is suited for CNC turning centers and manual lathes where precision and tight corner geometry are required.\u003c\/p\u003e\n\u003cp\u003eThe 6403069 is rated for universal primary workpiece material compatibility, covering ISO material groups H, K, M, N, P, and S. This broad material range makes it applicable across steel, stainless steel, cast iron, non-ferrous metals, high-temperature alloys, and hardened materials. It is primarily used in small-diameter internal and external turning, threading, and grooving applications where minimal corner radius is critical. Machinists and CNC operators working in precision component manufacturing, aerospace, and medical part production will find this insert well suited to close-tolerance finishing and semi-finishing cuts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD-applied TiCN and TiN dual-layer coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eManufacturer grade IC508 optimized for a wide range of workpiece materials across ISO groups H, K, M, N, P, and S\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0039 inches (0.10 mm) for tight-tolerance and small-feature turning\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle (3 degrees) reduces cutting forces and is suitable for light finishing cuts\u003c\/li\u003e\n  \u003cli\u003eRight-hand, clamp-held UMGR insert style for secure seating in MiniCham series toolholders\u003c\/li\u003e\n  \u003cli\u003eIrregular insert shape with 7-degree relief angle reduces rubbing and supports free-cutting performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ISCAR MiniCham series toolholders that accept the UMGR 4.0-0.1 insert style with clamp-style holding.

Use the correct clamp screw torque driver recommended by the toolholder manufacturer to seat the insert without cracking the carbide substrate. Inspect the insert pocket and clamp for wear or debris before seating a new insert. Do not use inserts that show chipping, cracking, or coating delamination.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: UMGR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 4.0-0.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC508\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN and TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0039 inches (0.10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 3 degrees (Positive)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Irregular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: H; K; M; N; P; S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MiniCham\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\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  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6403069\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51738733084978,"sku":"6403069","price":176.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7bc9a53ab87a3e4230d76a135795f4d8.jpg?v=1788803612","url":"https:\/\/voomisupply.com\/products\/iscar-6403069-turning-insert-umgr-4-0-0-1-ic508-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
