It carries manufacturer grade TM2501 and is designed for precision metal-removal operations in CNC lathes and turning centers. The insert features an 80-degree diamond shape, a 5\/8-inch inscribed circle, a 1\/32-inch corner radius, and a neutral hand orientation. Four usable cutting edges and the MF4 chip breaker geometry make this insert a productive choice for medium finishing passes on difficult materials. Machinists and CNC operators working in job shops or production environments handle installation and indexing.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning, facing, and boring operations in both light-production and job-shop settings. Its primary target workpiece material is stainless steel, with steel as a secondary application. The MF4 chip breaker geometry is optimized for medium finishing cuts where chip control and edge stability on work-hardening alloys are critical. The negative rake angle and chamfered-and-honed cutting edge style support consistent edge life across repeated indexing cycles. Material grades M25, M30, and M35 cover a broad band of stainless and general-purpose steel applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD Duratomic multilayer coating — TiCN, Al2O3, and Cr — for extended tool life on stainless steel\u003c\/li\u003e\n  \u003cli\u003eMF4 chip breaker geometry optimized for medium finishing cuts and reliable chip evacuation\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert for maximum indexable value\u003c\/li\u003e\n  \u003cli\u003eChamfered and honed cutting edge style for edge stability on work-hardening materials\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, pin, and lever-lock toolholding systems\u003c\/li\u003e\n  \u003cli\u003eCompliant with both ANSI and ISO standards; ISO designation CNMG160608-MF4\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNMG-style toolholders that accept a 5\/8-inch inscribed-circle, 80-degree diamond insert with clamp, pin, or lever-lock holding.

Power down and lock out the machine spindle before indexing or replacing the insert. Seat the insert fully against the pocket locating surfaces before engaging the clamping mechanism — clamp, pin, or lever lock as applicable to the toolholder in use. Inspect the insert pocket for wear or debris before seating a fresh cutting edge to avoid premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CNMG542-MF4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG160608-MF4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 80 (80-degree included angle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TM2501\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, Cr — CVD Duratomic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0315 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\u003eInsert Length\u003c\/strong\u003e: 0.6346 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.6024 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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\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\u003eRake Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MF4\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 Holding Method\u003c\/strong\u003e: Clamp, Pin, Lever Lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M25, M30, M35\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: 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\u003ePackage Dimensions\u003c\/strong\u003e: 4.33 inches L x 1.97 inches W x 0.47 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.41 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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 03273915\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560646934834,"sku":"03273915","price":399.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e0cfc51d89bcc554843b6eb4d95433b4_c4f4cae8-4c4e-4731-94af-cc870b92de21.jpg?v=1786455199","url":"https:\/\/voomisupply.com\/products\/seco-03273915-cnmg542-mf4-tm2501-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
