With a 0.25 inch mill diameter and a 4-flute geometry, this tool delivers high surface finish quality and improved chip evacuation in finishing and semi-finishing passes. The 45-degree helix angle reduces cutting forces and vibration, supporting stable cuts at elevated feed rates. A 0.213 inch length of cut keeps the cutting zone tight, minimizing deflection in close-tolerance work. Licensed machinists and toolmakers install and run this tool on CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, profiling, and contour milling in both ferrous and non-ferrous materials where a precise ball-nose radius is required. The uncoated bright finish makes it appropriate for aluminum and other non-ferrous metals where coatings can cause built-up edge. The single-end configuration and 0.25 inch shank diameter fit standard collet and end mill holder systems common in job shops, tool rooms, and production environments. It is used in both prototype and production machining contexts where dimensional accuracy is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.25 inch ball nose diameter for accurate radius profiling and 3D contouring\u003c\/li\u003e\n\u003cli\u003e4-flute design improves surface finish and feed rate capability over 2-flute alternatives\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle reduces cutting forces and dampens vibration\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suited for aluminum and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eReduced neck diameter of 0.158 inches with 0.75 inch neck length enables access to tighter cavities\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement-compatible solid carbide ball end mill for use in standard 0.25 inch collets and end mill holders on CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully powered down and locked out before changing tooling. Seat the shank fully in a clean, undamaged collet or end mill holder and torque to the holder manufacturer's specification. Inspect the cutting edges for chips or damage before each use, and confirm runout with a dial indicator before production cutting.\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\u003eLength of Cut\u003c\/strong\u003e: 0.213 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.158 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: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWrap Angle\u003c\/strong\u003e: 270 degrees\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\u003eEnd Type\u003c\/strong\u003e: Single End\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 994716\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51733016281394,"sku":"994716","price":169.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c5044e4ddb8924f47e41c5b1bb8e74c.jpg?v=1788750505","url":"https:\/\/voomisupply.com\/products\/harvey-tool-994716-ball-end-mill-0-25-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
