It features a 3\/8 inch cutting diameter, a 1-3\/4 inch length of cut, and a 4-inch overall length, placing it in the extra-long category for extended reach operations. The four-flute, right-hand spiral design is paired with an AlTiN (aluminum titanium nitride) finish, which improves heat resistance and tool life in high-speed and dry machining conditions. The variable index geometry reduces harmonic vibration during cutting, and the centercutting capability allows for plunge entry. This end mill is used by machinists and tool-and-die professionals in precision CNC milling applications.\u003c\/p\u003e\u003cp\u003eThe SGS 70479 is suited for milling a broad range of materials including hardened steels, cast irons, stainless steels, carbon and alloy steels, and high-temperature superalloys, as indicated by the primary workpiece material codes H, K, M, P, and S. The extra-long length of cut makes it well-suited for deep-pocket milling, slotting, and profiling operations where a standard-length end mill cannot reach. It accepts a standard straight-cylindrical 3\/8 inch shank, compatible with a wide range of collet chucks and end mill holders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide micrograin construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for improved heat resistance in high-speed and dry cutting\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces chatter and harmonic vibration\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits direct plunge entry into workpiece\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral with four flutes for balanced material removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThe SGS 70479 is part of the SGS Series 7 end mill family and is compatible with materials designated under workpiece codes H, K, M, P, and S, covering hardened steels, cast irons, stainless steels, carbon and alloy steels, and superalloys.

Before changing tooling, ensure the machine spindle is fully stopped and the control is in a safe state. Verify runout at the collet or end mill holder before beginning a cut, as excessive runout accelerates edge wear. Always follow the machine tool manufacturer and cutting tool manufacturer guidelines for speeds, feeds, and depth of cut for the specific workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-3\/4 inches (1.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\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\u003eCentercutting\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\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: Extra Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.00000 \/ -0.00035 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: SGS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 70479\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51743291670834,"sku":"70479","price":115.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/addf95ea968c9bc23904ebb487c28625_80fc3ed6-3b75-44ac-9de5-8aa634adb878.jpg?v=1788845175","url":"https:\/\/voomisupply.com\/products\/sgs-70479-square-end-mill-3-8-inch-4-flute-altin-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
