The insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which delivers wear resistance and thermal stability across a range of cutting conditions. With an 80-degree diamond shape (C code), a 3\/4-inch inscribed circle, a 0.6986-inch insert length, and a 1\/16-inch corner radius, this insert is sized for medium-to-heavy stock removal. It ships as a neutral-hand insert with an N clearance angle, a 1\/4-inch thickness, and the MR chip breaker geometry. Licensed HVAC technicians are not the intended installer — this part is for machinist and tooling professionals.\u003c\/p\u003e\n\u003cp\u003eThis insert is optimized for turning stainless steel (ISO material group M) and belongs to the Sandvik Coromant T-Max P series. It is suited for external and internal turning where consistent chip control and edge integrity are required. The MR chip breaker geometry is designed to handle the gummy, work-hardening characteristics of austenitic and other stainless-steel alloys. It is held in the tool body by clamp and pin, and four cutting edges are available per insert, making it a cost-effective choice for production environments running medium-depth turning passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for thermal barrier and flank wear resistance\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond (CNMG) insert shape with 4 usable cutting edges\u003c\/li\u003e\n  \u003cli\u003eMR chip breaker geometry optimized for stainless steel turning\u003c\/li\u003e\n  \u003cli\u003eGrade 2025 carbide substrate suited for ISO M (stainless steel) applications\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with standard CNMG toolholders\u003c\/li\u003e\n  \u003cli\u003eClamp and pin holding method for secure, repeatable seating in the pocket\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNMG 644 toolholders accepting a 3\/4-inch inscribed circle insert with a 0.3120-inch hole diameter.

Power down and lock out the machine spindle before indexing or replacing the insert. Seat the insert fully in the pocket before tightening the clamp to manufacturer torque specifications for the toolholder in use. Inspect the toolholder pocket for chips or damage before seating a new insert to avoid premature edge failure or insert breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: 80-degree Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 2025\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiN (CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.6986 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/16 inch (0.0625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.3120 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\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 Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\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 Material\u003c\/strong\u003e: Stainless Steel (ISO Group M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG 19 06 16-MR 2025\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.69 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.08 inches L x 2.13 inches W x 0.53 inches H\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5725484\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51733848391986,"sku":"5725484","price":647.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/314b0538d875d4f3a97a4a17b7f200bb_cba9a6a9-5ab3-46bd-b447-0ba9a34e151f.jpg?v=1788759574","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5725484-turning-insert-cnmg644-mr-2025","provider":"Voomi Supply","version":"1.0","type":"link"}
