It features a 5\/16 inch diameter with a matching 5\/16 inch straight-cylindrical shank and a 1\/2 inch length of cut. The stub-length profile keeps the tool rigid under load, reducing deflection during aggressive cuts. A TiCN (titanium carbonitride) coating improves surface hardness and wear resistance. The 30-degree spiral flute geometry and right-hand cut with right-hand flute direction promote efficient chip evacuation. Variable index spacing helps suppress chatter on harder materials. This tool is installed and operated by machinists and CNC programmers in job shop and production environments.\u003c\/p\u003e\u003cp\u003eThe SGS 31245 is suited for milling ferrous and non-ferrous metals, high-temperature alloys, and composite materials. Its workpiece material codes cover cast iron, non-ferrous metals, stainless steel, non-metallic materials, carbon and alloy steels, and heat-resistant superalloys. The centercutting design allows plunge entry, making it usable for slot milling, profiling, and pocketing operations. The stub-length form keeps overhang minimal, which is especially useful in tight setups or shallow-pocket work where rigidity matters most.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves wear resistance and extends tool life on abrasive materials\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth cutting action and efficient chip removal\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic vibration and chatter\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables direct plunge entry for slotting and pocketing\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC and manual mill setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill compatible with standard straight-bore tool holders, collet chucks, and shrink-fit holders accepting a 5\/16 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or tool holder and torque the retention mechanism to the holder manufacturer specification. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear and reduces surface finish quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inches (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 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: TiCN\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\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\u003eLength Type\u003c\/strong\u003e: Stub\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: 16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.082 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: 31245\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51745386561842,"sku":"31245","price":64.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a63b73272de250b9af692cda6e55e37d_44a483a3-3665-47d8-ae66-97f40a2b9d08.jpg?v=1788863685","url":"https:\/\/voomisupply.com\/products\/sgs-31245-square-end-mill-5-16-inch-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
