Built from micrograin solid carbide and coated with TiCN for extended tool life and heat resistance, it carries a 0.25-inch diameter and a 40-degree helix angle optimized for chip evacuation and smooth cutting action. With 2 flutes and a right-hand cutting direction, this end mill is suited for medium-to-high-speed CNC machining operations across a range of ferrous and non-ferrous workpiece materials. Machinists and tooling technicians working in job shops, production machining, and mold-and-die applications will find it a dependable choice for finish and semi-finish passes.\u003c\/p\u003e\u003cp\u003eThis end mill is used in vertical and horizontal CNC machining centers for operations requiring a ball-nose profile, including 3D contouring, core and cavity work, and radius milling. Its stub-length classification and 0.375-inch length of cut make it appropriate for applications with shorter reach requirements where rigidity is a priority. The 0.25-inch shank diameter suits standard collet chucks and end mill holders common in most CNC setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.25-inch mill diameter with matching 0.25-inch shank for balanced tool geometry\u003c\/li\u003e\n\u003cli\u003e0.375-inch length of cut in a stub-length profile for improved rigidity\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces friction and extends tool life in abrasive materials\u003c\/li\u003e\n\u003cli\u003e40-degree right-hand spiral flutes promote efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eSingle-end design; 2.0-inch overall length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard addition to tooling inventories for CNC machining centers using ER collets or end mill holders with a 0.25-inch bore.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Secure the shank in a clean, properly sized collet or end mill holder and torque to the holder manufacturer's specification. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Confirm runout with a dial indicator before beginning a cut to protect both the tool and the workpiece.\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\u003eShank 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: 2.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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: TiCN\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\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: 12184128\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738452492594,"sku":"12184128","price":40.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f8624dd8ffb3412cefba10b43d5f04d.jpg?v=1788799682","url":"https:\/\/voomisupply.com\/products\/accupro-12184128-ball-end-mill-0-25in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
