At 0.0130 inches in diameter with a 0.0390-inch length of cut, this tool is built for fine detail work, micro-slot milling, and intricate contouring in hardened and difficult-to-machine materials. The micrograin carbide substrate provides the rigidity and edge retention necessary at this scale. A 30-degree helix angle promotes efficient chip evacuation in shallow, high-precision cuts. The bright uncoated finish makes it suitable for applications where coating buildup or heat transfer concerns would otherwise apply. Machinists and toolroom operators running CNC machining centers or manual mills will find this tool appropriate for miniature work.\u003c\/p\u003e\u003cp\u003eThis end mill is used in applications that require extreme precision at micro-scale dimensions. Typical environments include aerospace component machining, medical device manufacturing, mold and die work, and electronics fixture fabrication. The single-end configuration and 1\/8-inch shank diameter make it compatible with standard collet systems found on high-speed spindles and micro-machining setups. The 1.5-inch overall length keeps the tool compact and minimizes deflection during light, precise passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0130-inch ball nose cutting diameter for micro-scale milling and contouring\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for edge retention and rigidity at small diameters\u003c\/li\u003e\n\u003cli\u003e4-flute design balances chip load and surface finish in fine detail passes\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand spiral helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suits dry cutting and heat-sensitive applications\u003c\/li\u003e\n\u003cli\u003e1\/8-inch shank diameter fits standard miniature collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a miniature single-end ball end mill with a 1\/8-inch shank, compatible with standard collet systems on CNC machining centers and high-speed spindles configured for small-diameter tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the machine spindle fully stopped and the control in a safe state. Secure the 1\/8-inch shank firmly in a matching collet or tool holder, verifying runout before cutting. At this diameter, even minor runout will significantly affect tool life and surface finish. Follow machine manufacturer guidelines and applicable shop safety practices when handling micro-diameter carbide tooling, as the cutting edge is extremely fragile.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0130 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.0390 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: 4\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\u003eEnd Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\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\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: 12276906\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51750920782130,"sku":"12276906","price":50.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45d89d63b7e2066ebb917168359f3525.jpg?v=1788920617","url":"https:\/\/voomisupply.com\/products\/accupro-12276906-ball-end-mill-0-0130-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
