With a 0.0170-inch cutting diameter and a 0.0510-inch length of cut, this tool is built for small-feature work where dimensional accuracy is critical. The micrograin carbide construction delivers hardness and wear resistance at the cutting edge. Four spiral flutes in a right-hand cutting, right-hand flute direction provide efficient chip evacuation during finish and semi-finish passes. A 30-degree helix angle balances cutting forces across the flute length. Licensed machinists and CNC programmers handling micro-machining, die-and-mold work, or intricate part geometries rely on tools in this class.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for precision CNC milling operations where small radii, fine detail, or confined pocket work is required. The miniature series designation identifies it for micro-scale applications common in medical device, aerospace component, and instrumentation part machining. The 0.0510-inch length of cut limits engagement depth, which is standard practice at this diameter to reduce deflection and maintain accuracy. The bright\/uncoated finish makes it suitable for a range of materials where coating is not required or where regrinding after use is anticipated.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0170-inch ball nose diameter for micro-scale feature milling\u003c\/li\u003e\n\u003cli\u003e4-flute spiral configuration with right-hand cut and right-hand flute direction\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle for balanced cutting forces at small diameters\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish with no chipbreaker — suitable for regrind programs\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 1\/8-inch shank for standard miniature toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style miniature ball end mill for use in CNC machining centers and precision milling machines accepting a 1\/8-inch round shank toolholder or collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the machine powered down and spindle fully stopped. Secure the 1\/8-inch shank in a collet or end mill holder rated for the shank diameter tolerance range specified for this tool. At 0.0170-inch diameter, runout control at the toolholder is critical — verify TIR with a dial indicator before commencing a cut. Follow your shop's standard lockout\/tagout procedure before any tool change.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0170 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.0510 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\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\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\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 Weight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.75 x 0.75 x 0.75 inches\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: 12276910\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732463780146,"sku":"12276910","price":38.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ffbcf7842a9cedf27cc2610a89904e4b_3871983d-e1c3-4acd-afcd-1b3066cf9cf2.jpg?v=1788743058","url":"https:\/\/voomisupply.com\/products\/accupro-12276910-ball-end-mill-0-017-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
