It features a 1\/4 inch diameter cutting head with a 0.01 inch corner radius, a 3\/8 inch length of cut, and a 2.5 inch overall length. The two-flute, high-helix helical geometry promotes efficient chip evacuation, reducing heat buildup and improving surface finish on aluminum, brass, copper, and similar materials. The bright uncoated finish is well suited for applications where coating adhesion to the workpiece is a concern. This end mill is installed by machinists and tool-and-die professionals using standard end mill holders in CNC and manual milling setups.\u003c\/p\u003e\n\u003cp\u003eThe SGS 91250 is intended for roughing operations in non-ferrous metal applications. Its short-length flute geometry and straight cylindrical 3\/8 inch shank make it compatible with standard end mill holders across a range of milling machines. The single-end, centercutting-capable design supports both peripheral and plunge cutting. This tool is a coarse-pitch, right-hand cut, right-hand flute configuration suited for high-speed material removal in production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and long tool life in non-ferrous milling\u003c\/li\u003e\n  \u003cli\u003e0.01 inch corner radius reduces stress concentrations and edge chipping at workpiece corners\u003c\/li\u003e\n  \u003cli\u003eTwo-flute, high-helix helical design promotes aggressive chip evacuation\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for aluminum and other non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eCoarse pitch roughing geometry maximizes material removal rates\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard end mill holders without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard end mill holders.

Ensure the milling machine spindle is fully stopped and the machine is powered down or placed in an e-stop state before changing tooling. Secure the 3\/8 inch shank in a properly sized end mill holder or collet to the torque specification required by the holder manufacturer. Verify runout after installation and confirm correct tool offset entry in the machine controller before initiating a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.01 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 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\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated (Bright)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\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\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0004 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0020 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 45C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 91250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51730484232498,"sku":"91250","price":118.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/017d15fa88c692c589af916a2513c88e.jpg?v=1788718271","url":"https:\/\/voomisupply.com\/products\/sgs-91250-corner-radius-end-mill-1-4-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
