Built from submicron grain carbide, it delivers edge retention and wear resistance at elevated cutting speeds. The 3\/4 inch cutting diameter pairs with a 1-1\/2 inch length of cut and a 4 inch overall length, making it a standard regular-length tool suited to a wide range of slotting, profiling, and peripheral milling operations. A TiAlN coating improves thermal resistance and extends tool life in dry or semi-dry cutting conditions. Four spiral flutes at a 45-degree helix angle promote efficient chip evacuation and smooth cutting action.\u003c\/p\u003e\n\u003cp\u003eThis end mill is center cutting, allowing direct plunge entry into the workpiece without a pilot hole. It is ground with right-hand cut and right-hand flute geometry. The straight cylindrical shank measures 3\/4 inch in diameter, fitting standard ER and side-lock toolholders commonly found in CNC machining centers, knee mills, and manual vertical mills. Primary workpiece material codes indicate suitability for hardened steels, cast irons, stainless steels, carbon and alloy steels, and high-temperature alloys. It is sold individually and intended for installation by machinists and CNC operators working in job shop, production, or maintenance machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron grain solid carbide construction for superior hardness and edge stability\u003c\/li\u003e\n  \u003cli\u003eTiAlN finish for extended tool life and high-temperature performance\u003c\/li\u003e\n  \u003cli\u003e45-degree helix spiral flute geometry for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCenter cutting capability allows plunge and ramp entry cuts\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute orientation for standard CNC and manual mill spindles\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical 3\/4 inch shank for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3\/4 inch straight-bore toolholders including ER collet chucks, Weldon side-lock holders, and hydraulic chucks on CNC machining centers and conventional vertical mills.

Ensure the machine spindle is fully stopped and the tool path program is verified before securing the end mill in the toolholder. Use a calibrated torque wrench when tightening collet nuts or set screws to the toolholder manufacturer specifications. Inspect the cutting edges and shank for damage before each use, and confirm runout with a dial indicator after installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 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: 1-1\/2 inches (1.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 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\u003eCenter Cutting\u003c\/strong\u003e: Yes\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 Grain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 5620958\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51750203064626,"sku":"5620958","price":444.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0658810e801fe3f7406844ad2d44c81d.jpg?v=1788914281","url":"https:\/\/voomisupply.com\/products\/iscar-5620958-square-end-mill-3-4-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
