Built on the Flash Solid series platform, it features a 0.25 inch cutting diameter with three flutes and a 45-degree helix angle. The DLC (Diamond-Like Carbon) coating reduces friction and increases tool life in demanding cutting conditions. With a right-hand cutting and right-hand flute direction, this single-end tool is suited for finishing and semi-finishing passes where surface quality and dimensional accuracy are critical. Licensed machinists and CNC operators are the primary installers and users of this tooling.\u003c\/p\u003e\u003cp\u003eThis ball end mill is commonly used in CNC machining centers and manual mills for contouring, slotting, and 3D profiling of ferrous and non-ferrous materials. The 0.75 inch length of cut and 2.5 inch overall length make it well-suited for moderate-depth cavity work and die-mold applications where a compact reach is appropriate. The variable index geometry helps reduce harmonic vibration during aggressive cutting passes, improving finish quality and tool stability.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.25 inch diameter ball end profile for contouring and 3D surface milling\u003c\/li\u003e\n\u003cli\u003e3-flute solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eDLC coating reduces friction and extends tool life in dry and semi-dry cutting\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle improves chip evacuation and cutting efficiency\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces chatter and vibration\u003c\/li\u003e\n\u003cli\u003eSingle-end design with right-hand cut and right-hand spiral flute direction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-specification solid carbide ball end mill in the ISCAR Flash Solid series, compatible with standard 1\/4 inch diameter collets and end mill holders on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the 0.25 inch shank fully and evenly in a matched collet or end mill holder to the recommended engagement depth for the holder type in use. Verify runout with a dial indicator before beginning production cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: DLC (Diamond-Like Carbon)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Flash Solid\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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3399360\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51729574199602,"sku":"3399360","price":69.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/151efb9af154d9d97245ce0139b0e8ef.jpg?v=1788706295","url":"https:\/\/voomisupply.com\/products\/iscar-3399360-ball-end-mill-0-25-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
