This single-end insert features a 0.161 inch cutting width and a 0.009 inch corner radius, with a right-hand lead angle of 6 degrees. The T25M manufacturer grade carbide substrate is finished with a CVD-applied TiC\/TiCN\/TiN multilayer coating, providing thermal resistance and edge durability during interrupted or continuous parting cuts. Chipbreaker designation is 16. The overall insert length is 0.354 inches. It is held in the toolholder via a clamp-style insert holding method.\u003c\/p\u003e\u003cp\u003eThis insert is suited for OD parting and cutoff applications across a broad range of metalworking operations, classified for universal primary workpiece material compatibility with a material grade of C5. It is intended for use in Series 150.10 compatible toolholders. Typical installation scenarios include CNC lathe and turning center parting operations in production and job-shop environments. Machinists and toolroom technicians working with steel, stainless, cast iron, and similar materials will find this insert appropriate for general parting work. Minimum order quantity is 10 pieces; individual package quantity is 1.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with T25M grade for high wear resistance in parting applications\u003c\/li\u003e\n\u003cli\u003eCVD multilayer coating: TiC\/TiCN\/TiN for improved thermal and abrasion performance\u003c\/li\u003e\n\u003cli\u003e0.161 inch cutting width for precise parting and cutoff geometry\u003c\/li\u003e\n\u003cli\u003e0.009 inch corner radius for controlled edge engagement\u003c\/li\u003e\n\u003cli\u003e6-degree right-hand lead angle for directional chip flow management\u003c\/li\u003e\n\u003cli\u003eClamp-style insert retention for secure seating in compatible toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Series 150.10 clamp-style cutoff and parting toolholders accepting a size 4 insert.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician with the machine fully powered down and the spindle locked before seating the insert. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer to secure the insert without over-clamping. Inspect the insert pocket for chips or debris before installation, as contamination can cause premature insert failure or poor surface finish. Follow the toolholder manufacturer guidelines for feed rate and depth-of-cut limits appropriate to this insert geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Grade\u003c\/strong\u003e: T25M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiC\/TiCN\/TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.161 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.009 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.354 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 6 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: 16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 150.10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Parting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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\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: 74016521\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558315491634,"sku":"74016521","price":304.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c656a1b8525e3dbb75ea3b722ecf77c2.jpg?v=1786409263","url":"https:\/\/voomisupply.com\/products\/seco-74016521-carbide-cutoff-insert-t25m-0-161in-series-150-10","provider":"Voomi Supply","version":"1.0","type":"link"}
