With a 0.25-inch mill diameter and a 0.375-inch length of cut, this tool is built for contouring, profiling, and 3D surface work where a ball-nose geometry is required. The 2-inch overall length and 0.25-inch shank diameter fit standard ER and straight-shank toolholders. A 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. The micrograin carbide substrate provides edge retention and rigidity suited to demanding CNC milling applications.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual knee mills where tight tolerances and fine surface finishes are required. The stub length classification makes it well suited for short-reach applications where rigidity is critical, such as pocket milling, die and mold work, and contouring operations. Right-hand cutting and right-hand flute direction are standard for conventional and climb milling on most machining setups. The uncoated finish is appropriate for non-ferrous metals, plastics, and certain ferrous materials where coating is not required or where re-sharpening is anticipated.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBall-nose geometry for 3D contouring, profiling, and radius floor work\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for edge retention in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle for efficient chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eStub length body improves rigidity and minimizes deflection in short-reach setups\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.000 to -0.002 inches for predictable fit and finish\u003c\/li\u003e\n\u003cli\u003eSingle-end design; uncoated finish suitable for non-ferrous metals and plastics\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for 0.25-inch straight-shank toolholders and ER collet chucks used in CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state before changing tooling. Seat the shank fully into the collet or toolholder and torque the retention nut to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a production cut, as excess runout accelerates wear on small-diameter carbide end mills.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\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\u003eVariable Index\u003c\/strong\u003e: No\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: 12184127\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730956386610,"sku":"12184127","price":39.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/367b82b89dd9dde2213d25f9c7990a86.jpg?v=1788725270","url":"https:\/\/voomisupply.com\/products\/accupro-12184127-ball-end-mill-0-25-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
