It carries the ANSI insert code TNMG544 and ISO code TNMG270616, with a 60-degree triangular shape and a neutral hand orientation. The MR4 chip breaker geometry is engineered for roughing and medium machining applications, delivering a cutting edge style classified as T-Land. With a 5\/8 inch (0.6250 inch) inscribed circle and a 1\/16 inch (0.0630 inch) corner radius, this insert is sized for moderate-to-heavy depth-of-cut work. Licensed machinists, tool and die operators, and CNC turning center technicians are the primary installers of this insert.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, boring, and back turning operations on superalloys and titanium workpieces where high wear resistance through high toughness is required. The 883 grade targets S-category primary workpiece materials (superalloys and titanium) and also covers secondary material codes M, K, N, and H, making it a versatile option across multiple work materials. Negative rake and negative side clearance geometry support stable, controlled cuts at moderate-to-high feed rates. It is compatible with toolholders that accept clamp, pin, or lever lock insert holding methods.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTNMG triangular insert shape with 60-degree included angle and 6 cutting edges for extended tool life per insert\u003c\/li\u003e\n\u003cli\u003eMR4 chip breaker optimized for roughing and medium machining on superalloys and titanium\u003c\/li\u003e\n\u003cli\u003eUncoated 883 grade carbide substrate — high wear resistance to high toughness (S10, S20, S30 material grades)\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation — compatible with both left-hand and right-hand toolholders\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.9291 inches supports substantial material removal per pass\u003c\/li\u003e\n\u003cli\u003eMulti-use geometry supports turning, facing, boring, and back turning in a single insert style\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with toolholders designed for TNMG-style inserts using clamp, pin, or lever lock holding methods.

Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torque wrench and manufacturer-specified clamping hardware for the toolholder type — do not overtighten clamp screws, as this can fracture the carbide substrate. Confirm insert seating and edge indexing before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TNMG544\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TNMG270616\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: T - Triangle, 60 degrees included angle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 5\/8 inch (0.6250 inch \/ 15.88 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/16 inch (0.0630 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inch (0.2500 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 1.0827 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.9291 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 6\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: Uncoated (Bright)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 883\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: S10, S20, S30\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MR4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Roughing, Medium Machining\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: T-Land\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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Superalloys and Titanium (Code S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material Codes\u003c\/strong\u003e: M, K, N, H\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\u003eSeries\u003c\/strong\u003e: TNMG-MR4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\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: 00007670\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51561582297394,"sku":"00007670","price":386.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d5a5044142d98c4fa69864eb586ae9a1.jpg?v=1786465978","url":"https:\/\/voomisupply.com\/products\/seco-00007670-turning-insert-tnmg544-mr4-48-883-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
