Built to miniature-series tolerances, this single-end tool features a 1\/4 inch mill diameter, a 3\/8 inch length of cut, and a 6 inch overall length. The micrograin carbide construction delivers rigidity and wear resistance for consistent performance in ferrous and non-ferrous materials. With a 30-degree helix angle and a chipbreaker geometry across its 3 spiral flutes, it is suited for high-precision contouring, slotting, and profiling operations. The bright\/uncoated finish makes it straightforward to inspect for wear.\u003c\/p\u003e\n\u003cp\u003eThis ball end mill is intended for use on CNC machining centers and manual mills requiring a miniature-series tool with extended reach capability. The 1\/4 inch shank diameter matches standard ER collet and end mill holder tooling. It is well-suited for die and mold work, aerospace components, and intricate part features where a tight mill diameter tolerance of +0.0000\/-0.0010 inches is required. Machinists working in tool rooms, production shops, and job shops will find this tool appropriate for finish milling contoured surfaces and tight-tolerance pockets.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003e3 spiral flutes with chipbreaker geometry for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle supports smooth cutting action on contoured surfaces\u003c\/li\u003e\n  \u003cli\u003eExtended reach design accommodates deeper cavity and pocket work\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish allows direct visual inspection of cutting edges\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style miniature-series ball end mill compatible with standard 1\/4 inch shank end mill holders and ER collet systems used on CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the holder to the recommended gauge line and torque the retention hardware per the toolholder manufacturer specifications. Verify runout with a dial test indicator before beginning a production cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\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: 6 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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: Yes\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: +0.0000\/-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\u003eNeck Length\u003c\/strong\u003e: 3.75 mm\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\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: 14881863\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747459957042,"sku":"14881863","price":75.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec5cddab2e951fada45dd3f75de1e439.jpg?v=1788880527","url":"https:\/\/voomisupply.com\/products\/accupro-14881863-ball-end-mill-1-4-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
