The insert features a PVD-applied TiN and TiAlN multilayer coating over a submicron carbide substrate, delivering a balance of wear resistance and toughness suited for steel, stainless steel, cast iron, and special or super alloys. The 55-degree diamond (rhombic) insert shape provides a strong, versatile cutting geometry. With a 0.5-inch inscribed circle and a 0.031-inch corner radius, it handles roughing and medium machining passes with a maximum depth of cut of 0.138 inches (3.51 mm). Licensed machinists and CNC lathe operators working in production or job-shop environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis insert is part of the ISCAR Isoturn series and is engineered for universal workpiece material applications coded P, M, K, and S — covering carbon and alloy steels, stainless steels, cast irons, and heat-resistant super alloys. The VL chip breaker geometry is optimized for both roughing and medium machining chip loads. The insert also supports boring applications, making it suitable for both OD turning and ID boring tool holders that accept the DNMG insert style. It conforms to ISO 13399 standards and carries the ISO size code 150408.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC908 grade with PVD TiN and TiAlN coating for high wear resistance and edge toughness across multiple material groups\u003c\/li\u003e\n\u003cli\u003e55-degree diamond (rhombic) insert shape with negative side clearance for rigid, stable cutting\u003c\/li\u003e\n\u003cli\u003eVL chip breaker designed for roughing and medium machining operations\u003c\/li\u003e\n\u003cli\u003eSubmicron carbide substrate supports consistent edge life in demanding cuts\u003c\/li\u003e\n\u003cli\u003eMulti-use capable: external turning and boring applications\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 for standardized tool assembly and data exchange\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in DNMG-style turning and boring tool holders that accept inserts with a 0.5-inch inscribed circle, negative clearance angle, and clamp or pin holding methods.

Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torque wrench and clamp screw specified by the tool holder manufacturer — do not overtighten the clamp, as this can chip the insert edge or damage the pocket. Inspect the insert pocket and seating surface for chips or debris before installation to ensure proper seating and runout control.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DNMG432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DNMG150408\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: D - Diamond (Rhombic) 55 Degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC908\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN and TiAlN (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSubstrate Material\u003c\/strong\u003e: Submicron Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.031 inches (1\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 15.49 mm (0.61 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.187 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.138 inches (3.51 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees (Negative Clearance)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: VL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Roughing and Medium Machining\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\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 Materials\u003c\/strong\u003e: Steel (P), Stainless Steel (M), Cast Iron (K), Special and Super Alloys (S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5505848\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51748675879218,"sku":"5505848","price":297.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/99a93a2cd2ddbf0d29c3a098de2282d7.jpg?v=1788896511","url":"https:\/\/voomisupply.com\/products\/iscar-5505848-dnmg432-vl-ic908-turning-insert-55-deg-diamond","provider":"Voomi Supply","version":"1.0","type":"link"}
