The insert carries a CVD-applied Duratomic multilayer coating — TiCN, Al2O3, and Cr — classified as grade TP1501, which provides wear resistance and thermal stability during interrupted and continuous cuts. With a 1\/2-inch inscribed circle, an 0.250-inch corner radius, and a full-radius round shape, it delivers 8 usable cutting edges per insert. The M3 chip breaker geometry features a chamfered and honed cutting edge suited for medium-depth steel machining. This is an industry-standard RNMG format insert installed by machinists and CNC operators in production turning environments.\u003c\/p\u003e\n\u003cp\u003ePrimary application is turning, facing, and profiling of steel (ISO material group P, grades P10 and P20). Secondary workpiece materials include cast iron and hard materials (ISO groups K and H). The round insert shape and full-radius geometry make it effective for profiling passes and contour turning where a large cutting arc is beneficial. The neutral hand designation means the insert is suitable for both right-hand and left-hand tool holders that accept the RNMG mounting standard. Typical install scenarios include high-volume production turning and job-shop operations running medium carbon and alloy steels.\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 steel\u003c\/li\u003e\n  \u003cli\u003e8 cutting edges per insert — full-radius round shape maximizes value per insert\u003c\/li\u003e\n  \u003cli\u003eM3 chip breaker with chamfered and honed edge for medium-depth cuts\u003c\/li\u003e\n  \u003cli\u003eNegative rake, 0-degree relief angle — compatible with clamp, pin, and lever-lock toolholders\u003c\/li\u003e\n  \u003cli\u003eMulti-use geometry supports turning, facing, and profiling in a single insert style\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; ISO code RNMG120400-M3\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in RNMG-style toolholders that accept a 1\/2-inch inscribed circle round insert with a 0.203-inch hole diameter, using clamp, pin, or lever-lock holding methods.

Always index or replace inserts with the machine spindle stopped and the machine in a locked-out, de-energized state per applicable lockout\/tagout procedures. Seat the insert fully against the pocket and verify the clamping mechanism — clamp, pin, or lever lock — is torqued per the toolholder manufacturer's specification before resuming cuts. Inspect the pocket for chips or debris before seating a new edge to avoid insert rocking or premature breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: RNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: RNMG-M3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: RNMG43-M3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: RNMG120400-M3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TP1501\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: TiCN, Al2O3, Cr (CVD Duratomic)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Round (Code R)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1874 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: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: M3\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\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees (Clearance Code N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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: Steel (ISO P — P10, P20)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron (ISO K), Hard Material (ISO H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Facing, Profiling, 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: 0.02 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: 02959969\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563119968562,"sku":"02959969","price":262.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a9fbdc9c4a6eae34793c630f44c63c11_d005f889-a4c1-42ae-ac6a-f0012efe1abc.jpg?v=1786490893","url":"https:\/\/voomisupply.com\/products\/seco-02959969-turning-insert-rnmg43-m3-tp1501-round-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
