With a 0.0313-inch mill diameter and a 0.0625-inch length of cut, this tool is built for fine detail work and tight-tolerance machining. The four-flute, double-end design with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. An AlTiN coating provides thermal resistance and extended tool life when machining hard or abrasive materials. The micrograin carbide substrate supports edge integrity at elevated cutting speeds. This end mill is installed and operated by machinists and CNC programmers in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThe SGS 31218 is suited for milling ferrous and non-ferrous metals, high-temperature alloys, and composite materials. Its stub-length geometry and 0.125-inch shank diameter make it well matched to high-speed spindles with tight reach requirements. The double-end configuration provides two usable cutting ends, extending tool service intervals. Right-hand cutting and right-hand flute direction are standard for conventional CNC milling setups. Primary workpiece material codes include H, K, M, N, P, and S, covering a broad range of steels, cast irons, non-ferrous metals, and superalloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0313-inch ball nose diameter for fine-detail and contour milling\u003c\/li\u003e\n\u003cli\u003eFour flutes with 30-degree helix angle for balanced chip load and surface finish\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for high-temperature wear resistance\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two cutting ends per tool\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for edge stability at high feeds\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.000 to -0.002 inches for consistent fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CNC machining centers and manual mills accepting a 0.125-inch shank diameter collet or end mill holder.

Secure the 0.125-inch shank in a properly sized collet or end mill holder, ensuring full seating depth before tightening. Verify runout with a dial indicator before beginning a cut, especially at this diameter, where small deviations have an outsized effect on tool life and part accuracy. Consult the machine tool manufacturer and cutting data tables for appropriate speeds, feeds, and depth of cut for the target workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0313 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 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 Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Double\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 14B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 31218\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51755294261554,"sku":"31218","price":66.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/30862f8a34e8fc584b4151cb1067e541.jpg?v=1788953225","url":"https:\/\/voomisupply.com\/products\/sgs-31218-ball-end-mill-0-0313-in-4-flute-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
