With a 0.25-inch diameter and a 40-degree helix angle, this tool delivers efficient chip evacuation and smooth cutting action across a range of workpiece materials. The four-flute, right-hand spiral configuration provides rigidity and surface finish quality suited to finishing and semi-finishing passes. The bright, uncoated carbide construction makes it well-suited for non-ferrous metals and materials where coating adhesion or heat buildup is a concern. Licensed machinists and CNC operators are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard applications requiring a 3\/8-inch shank in CNC machining centers and manual mills. The double-end design extends tool life by offering two usable cutting ends, reducing per-operation tooling cost. With a 0.625-inch length of cut (LOC) and a 3-inch overall length (OAL), this tool is suited for regular-reach slotting, profiling, and contouring operations where extended reach is not required. It performs well in aluminum, brass, plastics, and similar workpiece materials in both production and job-shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.25-inch ball end cutting diameter for precise radius profiling\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand spiral flute design for rigidity and finish quality\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eDouble-end configuration provides two cutting ends per tool\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating buildup risk on non-ferrous materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or production end mill for CNC machining centers and manual mills accepting a 3\/8-inch straight shank toolholder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Secure the 3\/8-inch shank in a properly sized collet or end mill holder and torque the toolholder to the machine manufacturer's specification. Verify spindle speed and feed rate settings against material-specific cutting data before engaging the workpiece. Inspect both cutting ends for chipping or wear before use and between tool changes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.625 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\u003eOverall Length (OAL)\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Double End\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\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\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: 12185313\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732936196402,"sku":"12185313","price":121.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6c6dc6a91ecb2793105a58d07d5f8fd1.jpg?v=1788749054","url":"https:\/\/voomisupply.com\/products\/accupro-12185313-ball-end-mill-0-25-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
