Built from micrograin carbide stock, it delivers the rigidity and edge retention required for demanding cuts in ferrous and non-ferrous materials. The 30-degree helix angle promotes efficient chip evacuation, while the variable index design reduces harmonic vibration and chatter at the spindle. At 0.4375 inches in diameter with a 0.625-inch length of cut, this is a stub-length tool optimized for rigidity over reach. It is installed and operated by machinists and CNC programmers working on mills, machining centers, and manual knee mills.\u003c\/p\u003e\n\u003cp\u003eThe SGS 31619 suits a broad range of workpiece materials including cast iron, non-ferrous alloys, stainless steel, titanium alloys, and high-temperature alloys, as indicated by material codes H, K, M, N, P, and S. Its uncoated finish makes it well suited for applications where coating buildup would be a concern or where the substrate itself provides adequate performance. The centercutting geometry allows plunge entry directly into the workpiece. The straight cylindrical shank accepts standard end mill holders, collet chucks, and shrink-fit tooling sized for 7\/16-inch shank diameters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for superior hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003e4-flute configuration with 30-degree helix for balanced chip evacuation and feed capacity\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces chatter and harmonic vibration\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry enables direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eStub length design maximizes rigidity and minimizes deflection at the cutting zone\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral flute for use in standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with workpiece material codes H, K, M, N, P, and S, covering cast iron, non-ferrous alloys, malleable materials, stainless steels, titanium alloys, and high-temperature alloys.

Power down and lock out the spindle before inserting or removing the end mill from its holder. Ensure the shank is fully seated and the holder is torqued to the toolholder manufacturer's specification before initiating any cut. Inspect the cutting edges for chipping or wear before each use, as solid carbide tools can fail suddenly if run with a damaged edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 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\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\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\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: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 31619\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51731946307890,"sku":"31619","price":81.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fedc02579a746cbb8e8e6558243e53dd.jpg?v=1788737045","url":"https:\/\/voomisupply.com\/products\/sgs-31619-square-end-mill-7-16-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
