Built from submicron solid carbide and finished with a DLC (Diamond-Like Carbon) coating, it delivers extended tool life and reduced friction in demanding cutting environments. The 3-flute geometry with a 45-degree helix angle promotes efficient chip evacuation and smooth surface finishes. At 0.25 inches in diameter with a 1-inch length of cut and 3-inch overall length, this end mill suits tight-tolerance work in both manual and CNC setups. Variable index flute spacing helps reduce chatter during aggressive cuts.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling operations on ferrous and non-ferrous materials where a sharp, durable carbide tool with a high-performance coating is required. Typical applications include slotting, profiling, and peripheral milling in job shop, production, and tool-and-die environments. The right-hand cutting and right-hand flute direction make it compatible with standard spindle configurations on vertical machining centers and manual knee mills. Single-end design allows straightforward tool holding in standard collet or end mill holders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for high hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eDLC coating reduces friction and extends tool life in dry or semi-dry cutting\u003c\/li\u003e\n\u003cli\u003e3-flute, 45-degree helix design promotes chip clearance and surface finish quality\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic chatter during cutting\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capability allows plunge entry into workpieces\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for any machine tool accepting a 1\/4-inch shank end mill via collet chuck, end mill holder, or shrink-fit toolholder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe lockout state before changing tooling. Seat the shank fully and evenly in the holder to the recommended gauge-line depth per the holder manufacturer. Inspect the cutting edges for chips or damage before each use and replace if the DLC coating shows excessive wear or edge breakdown.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: DLC (Diamond-Like Carbon)\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\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\u003eEnd Type\u003c\/strong\u003e: Single End\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: 3398983\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51735295951154,"sku":"3398983","price":68.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9b46719eed6c3e0048b8d9a4fe9cdc66.jpg?v=1788771558","url":"https:\/\/voomisupply.com\/products\/iscar-3398983-square-end-mill-1-4-in-3-flute-carbide-dlc","provider":"Voomi Supply","version":"1.0","type":"link"}
