Built from super micrograin carbide, it delivers the edge retention and rigidity required for tight-tolerance slotting, profiling, and plunge cuts. The 4-flute, single-end configuration with a 30-degree helix angle balances chip evacuation with surface finish quality. At 0.0781 inches in diameter with a 0.125-inch length of cut, this is a stub-length tool suited for short-reach work where rigidity is critical. The centercutting geometry allows direct plunge entry without a pre-drilled pilot hole. Licensed machinists and CNC operators are the primary installers of this tool type.\u003c\/p\u003e\u003cp\u003eThis end mill fits applications requiring small-diameter precision cutting in ferrous and non-ferrous metals, plastics, and composites. The stub-length profile minimizes deflection, making it a practical choice for high-speed CNC milling centers and manual knee mills where chatter control matters. The 0.125-inch straight cylindrical shank seats directly into standard collets and end mill holders of matching bore. It ships as a single unit and is uncoated, which suits re-sharpening workflows where coating removal would otherwise be a concern.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSuper micrograin solid carbide construction for extended tool life and edge sharpness\u003c\/li\u003e\n\u003cli\u003e4-flute geometry balances material removal rate with finish quality\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eStub length of cut (0.125 inches) maximizes rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eUncoated finish supports re-sharpening and use in non-ferrous materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for SGS Series 1820 stub-length square end mills with a 0.125-inch straight cylindrical shank; compatible with standard collet chucks and end mill holders of matching bore size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or CNC setup technicians. Power down and lock out the spindle before changing tooling. Seat the shank fully into the collet or holder and torque the retention mechanism per the toolholder manufacturer specification. Inspect the cutting edges for chips or damage before each use; a damaged end mill in a high-speed spindle is a safety hazard.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/64 inch (0.0781 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, Super Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/8 inch (0.125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (1.500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eVariable Index\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\u003eSeries\u003c\/strong\u003e: 1820\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 00431\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51740419785010,"sku":"00431","price":31.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f47d3f4c3b31e93446c866186916a4c.jpg?v=1788824888","url":"https:\/\/voomisupply.com\/products\/sgs-00431-square-end-mill-5-64-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
