It carries the TH1000 manufacturer grade and features a multilayer TiAlSiN PVD coating applied over a carbide substrate. The insert geometry is a 55-degree diamond (rhombic) shape with an inscribed circle of 0.5 inches, a corner radius of 0.03125 inches, and an insert thickness of 0.25 inches. With four cutting edges and an MF2 chip breaker optimized for finishing operations, this insert delivers consistent chip control at light-to-moderate depths of cut. Machinists and CNC turning specialists install this insert on negative-rake toolholders using clamp, pin, or lever-lock holding methods.\u003c\/p\u003e\u003cp\u003eThis insert is intended for finishing operations on superalloys, titanium, and hardened materials — workpiece categories classified under material grades S05 and H05. The TH1000 grade provides high wear resistance suited to superalloys and titanium, along with a range of wear resistance to toughness for hardened materials. Typical applications include back turning, boring, facing, and standard OD turning. The MF2 chip breaker geometry supports finishing passes where close tolerances and surface finish quality are priorities. This insert is sold individually with a minimum order quantity of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiAlSiN multilayer PVD coating for high wear resistance in superalloy and hardened-material applications\u003c\/li\u003e\n\u003cli\u003e55-degree diamond (DNMG) insert shape with negative rake and negative side clearance\u003c\/li\u003e\n\u003cli\u003eMF2 chip breaker geometry optimized for finishing operations\u003c\/li\u003e\n\u003cli\u003eFour usable cutting edges per insert\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp, pin, and lever-lock toolholder systems\u003c\/li\u003e\n\u003cli\u003eChamfered and honed cutting edge style for edge stability at light depths of cut\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in DNMG-style negative-rake toolholders that accept a 442 ANSI size code (ISO 150608) insert.

Always index or replace inserts with the machine powered down and the spindle at a full stop. Use the appropriate torque wrench for the clamping screw — follow the toolholder manufacturer's specification for clamp torque, as no insert-specific value applies here. Inspect the toolholder pocket and seating surface for chips or wear before seating a new insert to ensure proper contact and dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DNMG-MF2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TH1000\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: TiAlSiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD Multilayer\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\u003eIncluded Angle\u003c\/strong\u003e: 55 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 Thickness\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03125 inches (1\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 1.2204 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2028 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.5787 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Size Code\u003c\/strong\u003e: 442\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Size Code\u003c\/strong\u003e: 150608\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: MF2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Pin, Lever Lock\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Superalloys and Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: S05, H05\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplications\u003c\/strong\u003e: Back Turning, Boring, Facing, Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 10\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 02730819\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558237864242,"sku":"02730819","price":354.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1ab821deb4d46f386214fac55acc500.jpg?v=1786406966","url":"https:\/\/voomisupply.com\/products\/seco-02730819-dnmg442mf2-th1000-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
