With a 3\/16-inch mill diameter and 4-flute geometry, it delivers smooth surface finishes and efficient chip evacuation in a compact form factor. The bright\/uncoated finish suits a wide range of general-purpose materials. A 30-degree helix angle balances cutting efficiency with tool rigidity. Micrograin carbide construction provides the hardness and wear resistance needed for tight-tolerance work. This tool is used by machinists and tool-and-die professionals operating CNC mills and manual vertical mills.\u003c\/p\u003e\u003cp\u003eThis miniature series ball end mill is suited for small-scale contouring, die work, mold cavities, and finish passes requiring close dimensional control. The 5\/8-inch length of cut and 2-inch overall length make it appropriate for shallow-to-moderate depth applications where reach and rigidity must be balanced. Right-hand cutting and right-hand flute direction are standard for conventional CNC mill setups. The single-end configuration and 3\/16-inch shank diameter allow direct installation into standard collets and end mill holders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for hardness and wear resistance in precision milling\u003c\/li\u003e\n\u003cli\u003e4-flute design promotes smooth surface finish and efficient chip removal\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances cutting performance with tool stability\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for general-purpose ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eMiniature series sizing supports die, mold, and fine-detail contouring work\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.0000\/-0.0010 inches ensures dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for miniature series solid carbide ball end mills with a 3\/16-inch shank diameter used in standard CNC and manual milling machine collet and end mill holder systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle is fully powered down and locked before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention hardware according to the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a cut to confirm proper seating and avoid tool deflection or premature wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 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: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000\/-0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001\/-0.0003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Miniature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12468420\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51753607332146,"sku":"12468420","price":31.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/25a0ed5428dc3ddf8f73b8d22884df97.jpg?v=1788938679","url":"https:\/\/voomisupply.com\/products\/accupro-12468420-ball-end-mill-3-16-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
