Built from micrograin carbide and coated with AlTiN, it handles elevated cutting temperatures and abrasive workpiece materials with consistent edge life. The 4-flute, right-hand spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finishes. The centercutting design allows plunge entry, expanding its versatility in slotting, profiling, and pocket milling operations. Machinists and CNC operators working in production and job-shop environments rely on this tool for tight-tolerance work across a range of material types.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling operations on ferrous and non-ferrous metals, cast irons, high-temp alloys, and stainless steels, corresponding to material codes H, K, M, N, P, and S. The extra-long length of cut of 1-3\/4 inches supports deeper axial depths of cut where a standard-length tool would fall short. The 4-inch overall length with a 3\/8-inch straight-cylindrical shank provides rigid toolholding in collet chucks, end mill holders, and shrink-fit systems. Variable index flute spacing reduces harmonic vibration during aggressive cuts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for wear resistance and edge stability\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating improves heat resistance and extends tool life in dry or semi-dry cutting conditions\u003c\/li\u003e\n  \u003cli\u003e4-flute, right-hand spiral with 30-degree helix angle for efficient chip flow and surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces chatter and harmonic vibration at higher feed rates\u003c\/li\u003e\n  \u003cli\u003eExtra-long 1-3\/4-inch length of cut supports deep pocketing and profile work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with workpiece materials classified under codes H, K, M, N, P, and S, including hardened steels, cast irons, stainless steels, non-ferrous metals, high-temperature alloys, and titanium alloys.

The machine spindle must be fully stopped and the machine placed in an e-stop or lockout state before tool changes. Verify shank runout and holder seating torque per the toolholder manufacturer's specifications before starting a cut. Confirm tool stick-out and depth-of-cut parameters against the programmed toolpath prior to running production.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 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: 1-3\/4 inches (1.7500 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\/8 inches (0.3750 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: 30 degrees\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\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\u003eLength Type\u003c\/strong\u003e: Extra 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, N, P, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1EL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: SGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 31884\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51752583070002,"sku":"31884","price":117.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/88542e0d5cb1f11a168254f083bb5ab8.jpg?v=1788929215","url":"https:\/\/voomisupply.com\/products\/sgs-31884-square-end-mill-3-8-in-4-flute-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
