Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for demanding milling applications. The 1\/2 inch cutting diameter pairs with a 1-1\/4 inch length of cut and a 45-degree helix angle, promoting efficient chip evacuation and smooth surface finishes. The bright, uncoated finish suits a range of general-purpose materials. Machinists and CNC operators in job shops, tool rooms, and production environments are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for CNC machining centers and manual knee mills running right-hand spindle rotation. The 1\/2 inch shank diameter fits standard ER collet chucks, end mill holders, and shrink-fit tooling commonly found in production and prototype shops. The 3 inch overall length keeps overhang manageable for stable cuts in typical cavity and contour work. It is appropriate for slotting, ramping, and helical interpolation where a ball nose profile is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for superior hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003e45-degree right-hand spiral helix for efficient chip flow and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch cutting diameter with a tight mill diameter tolerance of +0.000 \/ -0.002 inches\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch length of cut accommodates moderate-depth cavity and contour passes\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for general-purpose milling applications\u003c\/li\u003e\n  \u003cli\u003eSingle-end design with right-hand cutting direction for standard CNC spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2 inch shank ball end mill compatible with ER collet systems, end mill holders, and shrink-fit toolholders accepting a 1\/2 inch shank diameter on CNC machining centers and manual milling machines with right-hand spindle rotation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in an e-stop or powered-down state before loading or changing tooling. Seat the shank to the full recommended engagement depth in the toolholder and torque retention screws or collet nuts to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning a production cut, as excessive runout accelerates carbide edge wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches (3.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/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: +0.0001 \/ -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 313666\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51753850208562,"sku":"313666","price":111.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f938d1bce042a1ea39a5e80423538372.jpg?v=1788941478","url":"https:\/\/voomisupply.com\/products\/accupro-313666-ball-end-mill-1-2-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
