Built from micrograin solid carbide, it delivers the rigidity and edge retention required for high-speed finishing and semi-finishing passes. The 0.0300 inch cutting diameter pairs with a 30-degree helix angle and four-flute geometry to balance chip evacuation with surface finish quality. An AlTiN coating adds thermal resistance and hardness at the cutting edge, extending tool life in dry or near-dry machining conditions. Machinists and CNC operators working in aerospace, medical, mold-and-die, and precision instrument applications rely on this class of tooling for small-feature work.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for CNC machining centers and high-speed spindle setups handling small-part and micro-milling operations. The 0.0450 inch length of cut keeps the tool stiff relative to its diameter, reducing deflection during climb or conventional milling passes. The 1\/8 inch shank diameter fits standard collet chucks and micro-tool holders common on VMCs and compact machining centers. Single-end construction is standard for this miniature series. Right-hand cutting and right-hand flute direction conform to conventional CNC spindle rotation without modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0300 inch ball cutting diameter with 0.0450 inch length of cut for small-feature profiling\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for rigidity and edge retention in abrasive materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides elevated thermal resistance and hardness for dry or near-dry machining\u003c\/li\u003e\n  \u003cli\u003e4-flute, 30-degree right-hand spiral geometry balances chip clearance with surface finish\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch shank diameter fits standard collet and micro-tool holders\u003c\/li\u003e\n  \u003cli\u003eSingle-end, miniature series design with 1-1\/2 inch overall length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and high-speed spindle systems accepting a 1\/8 inch shank diameter collet or tool holder.

Seat the shank fully and evenly in the collet or holder to the specified grip length before torquing the retention nut to the tool holder manufacturer specification. At 0.0300 inch diameter, runout at the collet face must be minimized — use a high-precision collet or shrink-fit holder where possible to prevent premature tool breakage. Follow shop-specific feeds, speeds, and depth-of-cut guidelines appropriate for the workpiece material and machine capability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0300 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.0450 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 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: 30 degrees\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\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\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: 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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 12465793\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732817609010,"sku":"12465793","price":37.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/13fd26a9aa532a31045c0d1d5879feba.jpg?v=1788747146","url":"https:\/\/voomisupply.com\/products\/accupro-12465793-ball-end-mill-0-03-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
