With a 3\/8-inch cutting diameter, 1-1\/8-inch length of cut, and four flutes in a 30-degree right-hand spiral configuration, this tool delivers clean, accurate cuts in a wide range of workpiece materials. The micrograin carbide substrate provides hardness and wear resistance, while the Titanium Nitride (TiN) coating reduces friction and extends tool life. The variable index geometry helps break up harmonic chatter during aggressive cuts. At 3 inches overall length, this long-series end mill suits setups where added reach is required. Machinists and tool-and-die professionals install this tool in CNC machining centers and manual mills.\u003c\/p\u003e\n\u003cp\u003eThe SGS 31731 is suited for both roughing and finishing passes in materials spanning steels, cast irons, stainless steels, non-ferrous metals, high-temp alloys, and other machinable materials corresponding to ISO material groups H, K, M, N, P, and S. The long-series 1L designation makes it appropriate for pocketing, slotting, and profiling operations where standard-length tools cannot reach. It is centercutting, allowing plunge entry. Single-end design means the tool is replaced when the cutting end is worn. The straight cylindrical shank fits standard collet chucks and end mill holders with a 3\/8-inch bore.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for hardness and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends cutting tool life\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces harmonic chatter during cuts\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand helix, right-hand cutting direction\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry into workpiece\u003c\/li\u003e\n  \u003cli\u003eLong-series (1L) overall length of 3 inches provides extended reach\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for CNC machining centers and manual milling machines equipped with 3\/8-inch collet chucks, end mill holders, or compatible tool holders accepting a straight cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists following standard tooling setup procedures. Ensure the spindle is fully de-energized and locked out before changing tooling. Seat the shank fully in the collet or end mill holder to the minimum recommended insertion depth before tightening. Inspect the collet and holder bore for wear or runout before use, as excessive runout accelerates tool wear and reduces surface finish quality.\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\u003eLength of Cut\u003c\/strong\u003e: 1-1\/8 inches (1.125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 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, Micrograin Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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: Long (Series 1L)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\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\u003eCompatible Workpiece Material Groups\u003c\/strong\u003e: H, K, M, N, P, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 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: 31731\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51746621161778,"sku":"31731","price":102.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cb789a55c91f07af09095debe6857026.jpg?v=1788871852","url":"https:\/\/voomisupply.com\/products\/sgs-31731-square-end-mill-3-8-in-4-flute-solid-carbide-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
