Built in the Miniature series, it features a 1\/4 inch mill diameter, a 3\/8 inch length of cut, and a 4 inch overall length. The three-flute, right-hand spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Micrograin carbide construction delivers the hardness and edge retention needed for tight-tolerance work. The bright\/uncoated finish makes it suitable for a range of materials where coating-induced dimensional changes are a concern. A chipbreaker is included to help manage chip loads in deeper cuts.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finish and semi-finish milling operations requiring extended reach. The 1-1\/4 inch neck length allows the tool to reach into pockets and contoured surfaces that standard-length end mills cannot access. The 1\/4 inch shank fits standard collet systems commonly found on CNC machining centers and manual milling machines. It is a single-end tool intended for use by machinists and tool-and-die professionals working on small-scale components, mold work, and detailed profiling operations where ball-nose geometry is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for hardness and edge retention\u003c\/li\u003e\n\u003cli\u003e3\/8 inch length of cut with 1-1\/4 inch neck for extended reach capability\u003c\/li\u003e\n\u003cli\u003e3-flute right-hand spiral design at 30-degree helix for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eBall nose geometry for profiling, contouring, and 3D surface work\u003c\/li\u003e\n\u003cli\u003eChipbreaker feature to reduce chip loads in deeper milling passes\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish for broad material compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit miniature ball end mill for 1\/4 inch collet systems on CNC machining centers and manual mills requiring extended-reach tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer's collet and toolholder torque guidelines. Ensure the machine spindle is fully stopped and locked out before tool changes. Confirm shank seating depth meets the toolholder's minimum grip length to avoid pullout under load. Verify spindle RPM and feed rate settings are appropriate for the workpiece material before engaging the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eChipbreaker\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 14881866\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728574021938,"sku":"14881866","price":61.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/31ecce7dbf72a716f97648a7af8c7fe0.jpg?v=1788693513","url":"https:\/\/voomisupply.com\/products\/accupro-14881866-ball-end-mill-1-4-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
