Part of the Minimaster MM08 series, this carbide tip features a 0.315-inch cutting diameter, a 0.319-inch maximum depth of cut, and two flutes for efficient chip evacuation. The F30M grade carbide substrate is coated with TiAlN and TiN via a PVD process, delivering thermal resistance and edge durability at elevated cutting speeds. The MD03 chipbreaker geometry and 90-degree lead angle support stable profiling operations in steel, stainless steel, cast iron, superalloys, titanium, and hard materials. A right-hand cutting orientation and 0.157-inch corner radius complete the geometry. Installed by machinists and toolroom professionals on compatible Minimaster holders.\u003c\/p\u003e\u003cp\u003eThis milling tip is suited for profiling and contouring operations across a wide range of metallic workpieces, including P-grade steels (P20, P30), M-grade stainless steels (M10, M20), K-grade cast irons (K20, K30), and H-grade hard materials (H10). The 0.371-inch functional length and 9.42 mm extension from holder provide consistent reach geometry in tight-tolerance cavities. The tip meets ANSI standards and is indexed into Minimaster-compatible toolholders without coolant-through capability. Typical applications include die and mold profiling, aerospace component finishing, and general CNC milling where a repeatable, replaceable insert tip reduces downtime versus solid end mills.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.315-inch cutting diameter with 0.319-inch maximum depth of cut for precise ball-nose profiling\u003c\/li\u003e\n\u003cli\u003eF30M carbide grade with TiAlN and TiN PVD coating for heat resistance and extended tool life in ferrous and hard materials\u003c\/li\u003e\n\u003cli\u003eMD03 chipbreaker geometry with 90-degree lead angle supports stable chip control in profiling cuts\u003c\/li\u003e\n\u003cli\u003eTwo-flute, right-hand design with 0.157-inch corner radius for smooth surface finish in contoured features\u003c\/li\u003e\n\u003cli\u003eFits Minimaster MM08-series toolholders as a quick-change replaceable tip, reducing setup and changeover time\u003c\/li\u003e\n\u003cli\u003eRated for primary workpiece materials: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium, and Hard Material\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replaceable milling tip for SECO Minimaster MM08-series toolholders.

Power down and lock out the machine spindle before seating or removing any indexable tip. Use the correct Minimaster torque key to secure the tip; do not use substitutes that may damage the coupling interface. Inspect the seating surface on the holder for chips or damage before each installation to ensure accurate tip positioning and runout.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.315 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.319 inches (8.1 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.371 inches (9.42 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.157 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: F30M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN and TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: MD03\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MM08 (Minimaster)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 0.315-B90\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMilling Tip Type\u003c\/strong\u003e: Profile\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grades\u003c\/strong\u003e: P20, P30, M10, M20, K20, K30, H10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\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: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 74068812\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563158765874,"sku":"74068812","price":209.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b57cce7f266ba9e8f176ad9423bdb5fc.jpg?v=1786491771","url":"https:\/\/voomisupply.com\/products\/seco-74068812-ball-nose-milling-tip-0-315-in-carbide-mm08","provider":"Voomi Supply","version":"1.0","type":"link"}
