With a 1\/8 inch cutting diameter and a 45-degree helix angle, this single-end tool delivers clean, aggressive cuts across a range of workpiece materials. The four-flute spiral configuration and TiAlN coating provide thermal resistance and extended tool life under high-speed cutting conditions. At 1.5 inches overall length with a 3\/8 inch length of cut, it is suited for tight-tolerance finishing and profiling passes where rigidity and dimensional accuracy are critical. Licensed machinists and CNC programmers specify this geometry for applications requiring consistent surface finish in hard and abrasive materials.\u003c\/p\u003e\n\u003cp\u003eThis end mill is rated for use across multiple workpiece material categories, including hardened steels, cast irons, stainless steels, carbon steels, and high-temperature alloys, corresponding to material codes H, K, M, P, and S. The straight cylindrical shank measures 1\/8 inch in diameter, fitting standard collet toolholding systems on CNC mills and machining centers. The ISCAR IC900 material grade substrate is engineered for high-heat resistance, making it appropriate for dry or minimal-lubricant machining strategies in production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with IC900 grade substrate for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating provides oxidation resistance and extended tool life at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eFour-flute spiral design supports higher feed rates and improved surface finish\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting and right-hand flute direction for standard CNC spindle compatibility\u003c\/li\u003e\n  \u003cli\u003eRegular length classification with 3\/8 inch reach length suits close-tolerance profiling and slotting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for workpiece materials in categories H, K, M, P, and S, covering hardened steels, cast irons, stainless steels, carbon and alloy steels, and high-temperature superalloys.

Verify runout at the cutting edge before initiating a cut, as excessive runout accelerates edge wear on carbide tooling. Always confirm spindle speed and feed rate parameters against the material being machined before engaging the tool. Do not exceed the stated length of cut range of 0.3000 to 0.5000 inches to avoid tool deflection or premature breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 0.3000 to 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (1.5 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: IC900\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: H, K, M, P, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.637 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 5620950\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51746713665842,"sku":"5620950","price":65.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/47c52aeabb5a063086e657b7db1982c2.jpg?v=1788873131","url":"https:\/\/voomisupply.com\/products\/iscar-5620950-square-end-mill-1-8-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
