It carries the TP3501 manufacturer grade with a multilayer CVD coating of TiCN, Al2O3, and Cr under the Duratomic coating classification, delivering wear resistance and thermal stability during heavy cutting passes. The insert features a 90-degree square shape, neutral hand orientation, a 1\/16 inch corner radius, and a chamfered and honed cutting edge style. With four usable cutting edges and compatibility with clamp, pin, and lever lock holding methods, it suits boring, facing, and turning operations in demanding production environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is primarily targeted at machining steel (ISO material code P, grades P20, P30, P40) and secondarily at stainless steel (ISO material code M). The R7 chip breaker geometry and negative rake angle make it well suited for moderate to heavy depths of cut up to 0.689 inches. Machinists and CNC operators in production shops, job shops, and maintenance machining environments will find this insert appropriate for general turning work on ferrous materials where consistent chip control and tool life are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTP3501 carbide grade with Duratomic CVD multilayer coating: TiCN, Al2O3, and Cr for extended tool life on steel\u003c\/li\u003e\n  \u003cli\u003e90-degree square insert shape with four cutting edges, maximizing indexable usage per insert\u003c\/li\u003e\n  \u003cli\u003eR7 chip breaker geometry with chamfered and honed edge for controlled chip formation and edge stability\u003c\/li\u003e\n  \u003cli\u003eNegative rake angle suited for interrupted cuts and heavy feeds on ferrous workpieces\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, pin, and lever lock toolholder systems for flexible setup options\u003c\/li\u003e\n  \u003cli\u003eMulti-use application across boring, facing, and turning operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for toolholders accepting SNMM-style square inserts with a 0.3118 inch hole diameter and lever lock, clamp, or pin retention.

Always power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully and evenly in the pocket before tightening the clamping mechanism to avoid micro-fractures at the cutting edge. Inspect the insert pocket and shim for wear or debris each time the insert is indexed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TP3501\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, Cr (Duratomic CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square (90 degrees included angle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Width\u003c\/strong\u003e: 3\/4 inch (0.7500 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 (0.0630 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.3118 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.689 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\u003eRake\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\u003eChip Breaker\u003c\/strong\u003e: R7\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: Steel (P20, P30, P40)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Operations\u003c\/strong\u003e: Boring, Facing, Turning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: SNMM644-R7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SNMM190616-R7\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: 0.04 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\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: 03093876\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563582325042,"sku":"03093876","price":657.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/669392928aa75988e8ed69e1c5976432.jpg?v=1786499415","url":"https:\/\/voomisupply.com\/products\/seco-03093876-turning-insert-snmm644-r7-tp3501-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
