It features a 3\/32-inch (0.0938-inch) mill diameter with a 0.2810-inch length of cut, a 1\/8-inch shank diameter, and a 1-1\/2-inch overall length. The 4-flute, 30-degree helix geometry delivers smooth chip evacuation and a quality surface finish in tight-tolerance applications. The bright\/uncoated finish suits general-purpose use where coating is not required. Machinists and CNC operators running miniature detail work, slots, and contoured profiles will find this tool well-suited to the task.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use on CNC machining centers and manual mills requiring small-diameter tooling. Its miniature series classification makes it appropriate for fine detail cuts, small-pocket milling, and profiling operations common in mold making, die work, prototype machining, and precision part production. The micrograin carbide substrate supports rigidity and edge retention in demanding cuts. Right-hand cutting and right-hand flute direction are standard for conventional spindle setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/32-inch mill diameter with 0.2810-inch length of cut for miniature-scale operations\u003c\/li\u003e\n\u003cli\u003e4-flute spiral flute design for improved surface finish and chip flow\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances cutting force and chip evacuation\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for edge retention and rigidity\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for general-purpose and dry machining applications\u003c\/li\u003e\n\u003cli\u003eSingle-end, right-hand cut configuration compatible with standard CNC spindle setups\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 manual mills accepting a 1\/8-inch straight shank toolholder or collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 1\/8-inch shank fully and evenly in a collet or end mill holder to the recommended gauge-line depth before tightening. Verify runout with a dial indicator after installation to protect edge life and dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/32 inch (0.0938 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.2810 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 1-1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch\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 Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\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 End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0010 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0003 inch\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\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: 12378465\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729127571762,"sku":"12378465","price":32.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7b6c51bf51591b2952bd201fa4b521ec.jpg?v=1788700491","url":"https:\/\/voomisupply.com\/products\/accupro-12378465-ball-end-mill-3-32-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
