Built from ultra fine grain carbide and finished with a TiAlN coating, this tool delivers extended tool life and thermal resistance at elevated cutting speeds. The 45-degree helix angle promotes efficient chip evacuation and reduces cutting forces. With a 0.25 inch cutting diameter and 0.625 inch length of cut, this end mill is suited for finishing and semi-finishing passes where tight tolerances and surface finish quality are priorities. It is a single-end, straight-shank tool with right-hand cut and right-hand spiral flutes.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use on CNC machining centers and manual mills by machinists and tool-and-die professionals working in production or job-shop environments. The TiAlN coating and ultra fine grain substrate make it compatible with a wide range of workpiece materials including hardened steels, stainless steels, cast irons, non-ferrous metals, and high-temperature alloys, corresponding to ISO material groups H, K, M, P, and S. Its regular-length geometry fits standard tool holders for general milling, slotting, and profiling operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-flute geometry increases feed rates and improves surface finish compared to lower-flute-count tools\u003c\/li\u003e\n  \u003cli\u003eUltra fine grain solid carbide substrate provides rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiAlN finish improves thermal resistance for dry or high-speed cutting\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle promotes efficient chip evacuation and reduces chatter\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flute configuration for standard CNC spindle direction\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard ER collets and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ISO material groups H, K, M, P, and S, covering hardened steels, cast irons, stainless steels, general steels, and high-temperature alloys.

Ensure the spindle is fully powered down and locked before inserting or removing the tool. Confirm runout with a dial indicator after seating to avoid premature tool wear. Follow machine tool manufacturer guidelines and applicable shop safety standards when setting cutting parameters.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 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\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\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: Ultra Fine Grain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.64 pounds\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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5621955\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51727272050994,"sku":"5621955","price":81.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c44130903977c08885dec08e9d1e45b.jpg?v=1788675722","url":"https:\/\/voomisupply.com\/products\/iscar-5621955-square-end-mill-0-25-in-6-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
