Built to Series 63 specifications, it features a 3\/8 inch cutting diameter, a 1-1\/8 inch length of cut, and a 3-inch overall length with a matching 3\/8 inch straight-cylindrical shank. The four-flute, spiral configuration with a 38-degree helix angle promotes efficient chip evacuation and stable cutting performance. An AlTiN coating adds heat and wear resistance, making this end mill well suited for high-temperature alloy cutting. It is centercutting and uses a variable index geometry to reduce chatter. Installed by machinists and toolroom technicians working in CNC and manual milling setups.\u003c\/p\u003e\u003cp\u003eThe SGS 70478 is classified as a long-length end mill and targets ferrous and non-ferrous metals across primary workpiece material codes H, K, M, P, and S. These codes correspond to hardened materials, cast iron, stainless and heat-resistant alloys, general steels, and high-temperature superalloys. The right-hand cut and right-hand flute orientation are standard for conventional CNC vertical milling centers and manual knee mills. This tool is a single-end design, so once the cutting end is worn, the tool is replaced rather than reindexed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide micrograin substrate for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for elevated heat resistance in high-temperature alloy cuts\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle promotes smooth chip flow and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic chatter during aggressive passes\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eLong-length Series 63 classification for extended reach applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard straight-shank tool holders, collet chucks, and hydraulic chucks accepting a 3\/8 inch shank diameter.

Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading the end mill. Seat the shank fully into the collet or tool holder to the recommended grip length before torquing the retention mechanism. Verify runout with a dial indicator after clamping, as excessive runout will accelerate edge wear on a four-flute carbide tool.\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: 1-1\/8 inches (1.1250 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: 3 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\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eExtended Reach\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\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\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: H, K, M, P, S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 63\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\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: 70478\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51740409758002,"sku":"70478","price":99.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/addf95ea968c9bc23904ebb487c28625_9d082ddb-2a2c-47d3-831b-f547a549a503.jpg?v=1788824819","url":"https:\/\/voomisupply.com\/products\/sgs-70478-square-end-mill-3-8-in-4-flute-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
