With a 0.0420-inch cutting diameter and a 0.1260-inch length of cut, this tool is built for small-feature profiling, slotting, and contouring in hard and abrasive materials. The micrograin carbide construction provides the rigidity and edge retention needed in high-speed finishing passes. A 30-degree helix angle promotes efficient chip evacuation while maintaining surface finish quality. Licensed machinists and CNC operators working in tool and die, mold making, medical device, and aerospace environments are the primary users of this class of end mill.\u003c\/p\u003e\u003cp\u003eThis miniature end mill suits applications where fine detail and small-radius features are required on hardened or challenging workpiece materials. The 0.1260-inch length of cut keeps deflection minimal during critical finishing operations. Its 1\/8-inch shank diameter fits standard collet toolholding systems commonly found on CNC machining centers and high-speed spindles used in precision machining shops.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0420-inch ball cutting diameter for fine detail and small-feature milling\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for edge retention and rigidity\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand spiral helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for use with or without cutting fluid\u003c\/li\u003e\n\u003cli\u003eSingle end, right-hand cut configuration\u003c\/li\u003e\n\u003cli\u003e1\/8-inch shank diameter fits standard precision collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit miniature ball end mill for CNC machining centers and high-speed spindles accepting a 1\/8-inch shank diameter collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Secure the shank fully within the collet to the recommended engagement depth before tightening to avoid runout. Verify spindle speed and feed rate parameters are appropriate for the 0.0420-inch diameter before engaging the cut, as miniature end mills are sensitive to excessive load. Inspect the cutting edges under magnification before use to confirm no damage occurred during handling or storage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0420 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.1260 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eVariable Helix\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\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: 12463645\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51737842549042,"sku":"12463645","price":32.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3adb0633ee2caa057dabd4b8de07ee3.jpg?v=1788794195","url":"https:\/\/voomisupply.com\/products\/accupro-12463645-ball-end-mill-0-0420-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
